In the past, this old scanner has occasionally complained about its
Twain interface after some scanning but would work again after a warm
computer restart. The lid-detect function always worked, though I
couldn't use it.

Now, suddently, using any image program, including the one supplied
with it (iPhoto Plus 4, I get the flag "Flatbed scanner not ready",
and then, in the case of iPhoto Plus 4, I get "Twain error T009; error
opening twain data source T015; unable to find twain source mgr,
twain.dll -- copy twain.dll from source disk to Windows folder T039".
No dialog window now displays when I open the scanner cover. The
illumination lamp is on.

All the Twain and Twunk files are in place. I did copy over the
twain.dll file from the CD supplied with the scanner. No change. I
then uninstalled iPhoto Plus 4 and manually removed all the twain and
twunk folders and files, and then reinstalled iPhoto Plus 4, which
apparently installs whatever software runs the scanner. I have never
found, on my hard drive, whatever the latter is. No change. Since a
Mustek tech-support page says says the peripheral configuration mode
should be set to EPP, I tried that. No change. The scanner has
previously always been used with this mode set to the D850GB
motherboard's default, "Bi-directional".

Mustek also claims that, given such non-detection of its scanner from
an image program, if Windows in Safe Mode does detect the scanner, the
problem is a software conflict. In may case, the problem persisted in
Safe Mode. Actually, I didn't install any new programs between the
time the scanner worked and when it didn't.

I also tried running the copy of iPhoto Plus 4 that I had in the
contents of my previous HD, which I have existing on my present one.
Same symptoms. (That copy of iPhoto was never installed, just copied,
onto my present HD. The same resulted from a backup HD I shoved into
a module for it on my computer, but only set it as a slave. Same
symptoms.

I stronly doubt that the optical lid detector (LED-phototransistor
sensor) has gone bad. Maybe other hardware in the scanner is bad, but
I suspect some silly software problem. Of course, I loosened and
reseated the parallel cable, to no avail. The line-lug-mounted power
supply for the scanner seems to be at its normal temperature.

What could I further check? What files constitute the scanner-driving
software anyhow? How would I get Mustek -- US or Taiwan -- to solve
this problem on this scanner I bought in 1998? ;-) Hmm. It's still
a good scanner. . .once I replace the double-sided sticky tape holding
its glass down -- with metal clips held by screws, so that the copy
would stay evenly spaced from the scanning piece, even with a heavy
book laid on top of it to keep it flat.

It is sort of hard to follow the two prior messages and understand who
has the problem, but perhaps I can help? I have the same scanner and
have installed it on Win 98 and XP. Which OS are you dealing with?

If all the software loads without a problem, there should have been a
test to see if the scanner was detected. I assume you reached that
point and it was NOT detected? Do you know that the parallel port your
scanner is attached to works? You might want to attach your printer
without the scanner to prove in the port.

If you are using the pass through method (where the scanner is the
first device on the port), I would remove the printer after you
establish the port works, and get your scanner working by itself. In my
case, I had so many problems with the pass through method that I
installed a second parallel port in my computer. That solved a lot of
problems. But first just get the scanner to work with a single port and
no printer attached. Make sure your data cable is attached to the
correct connector on the rear of the scanner and to the working parallel
port on your computer. (Recently I took my scanner to a friends house
to establish if her scanner was bad, and upon re-attaching my scanner
hooked the data cable to the wrong connector on the scanner. I
encountered the same type of problem as you have. Duh!!)

Also check that your PS is getting power when you try to run the
scanner. You could test the output with a DVM. The lamp on the scanner
is controlled by the software if I recall correctly, so I don't believe
it will come on unless the scanner is detected via the parallel port.
Detection is also dependent upon the power reaching the scanner so that
it can respond to the software. C:\WINDOWS\TWAIN_32\A4S2_600\WATCH.exe
is the file that should turn on the scanner lamp.

C:\Program Files\iPhoto Plus 4\PROGRAMS\IPE.EXE is the file that start
Iphoto4 software. You could go to the individual files and double click
on them to start the sequence.

Write back after you see if your port is good, the software is present,
the data cable is attached properly, and maybe I can help more.

Win98SE

I don't recall its having included that test. I do know that
immediately thereafter, on trying to "Acquire" the scanner, I got the
stated error messages.

>Do you know that the parallel port your

It was working with the scanner the last time I used it -- I think the
day before. I did not try to use it with any other peripheral between
times, or even remove either end of its cable to the scanner.

>You might want to attach your printer
>without the scanner to prove in the port.

My printer uses USB. I found out some time ago that my printer (HP
5650) won't work right with a parallel bus chained through my scanner.
I don't think it will work right, in the mode I'm using it, with a
dedicated parallel bus. It's hard to believe that my parallel bus
suddenly quit working, when I didn't touch its connections at all.

I don't have a pass-through hookup. The scanner is on my only
parallel computer I/O and my printer uses USB only.

My old HP 932c printer USUALLY worked OK with that hookup, but I had
to be told that the reason I couldn't get my new much-faster printer
to work right, in that configuration, was due to that kluge. Luckily,
I had an extra USB port (but a 7-ft cable just barely makes to the
location of my printer.

Yes, I haven't changed either connection since it worked. My computer
has only one parallel I/O connection.

Yeah, well, I didn't touch MINE. It went south by itself. ;-)

No, no, no! The lamp stays on on this model, whenever its plug is
engaged with a hot power strip. Since this lamp stays lit, power is
at least getting to part of the scanner.

>Detection is also dependent upon the power reaching the scanner so that
>it can respond to the software. C:\WINDOWS\TWAIN_32\A4S2_600\WATCH.exe

It can't be for that purpose, because the lamp, as stated above, is
ALWAYS on. Watch.exe is installed at that location [vers. 1.0.0.1,
180K].

>C:\Program Files\iPhoto Plus 4\PROGRAMS\IPE.EXE is the file that start

I have done that with Ipe.exe and it brings up iPhoto 4 fine. I just
did that, then clicked 'Start', in that program's main window, and
then 'Scan'. The source window came up properly as it still has done
starting from the Desktop item. Then, instead of clicking 'Acquire'
in that window, I double-clicked Watch.exe in Windows Explorer.
Absolutely nothing happened; I didn't even get any error flags.

> Write back after you see if your port is good, the software is present,
>the data cable is attached properly, and maybe I can help more.

If YOUR scanner doesn't keep its illumination lamp on at all times
that scanner is plugged into an AC source, you have a different model
than mine, because I was informed by Mustek USA once (when I
complained about the lamp's needless usage [I had to replace it
once.]) that that is how the scanner I have is supposed to work.

If this is a hardware problem on the scanner's circuit board, I
suppose I'm out of luck, unless I run across a junked such board
somewhere. Fat chance. I certainly don't think trouble-shooting at
the board's component level is reasonable. But I think it's a
software problem. (Naturally, I'm a retired hardware type.) I just
wish I understood exactly which software files are involved in
detecting the scanner IN MY EXACT UNIT.

Ray,

That is the same OS that I use most of the time and am using now.

It might be that the test occurs after it detects your scanner as being
present? It has been a while since I installed the software, but there
is a test during the installation. I thought it asked you if you wanted
to do such a test? It really is a moot point, since detection would
come first anyway.

I don't mean to be sarcastic, but often people assume that what worked
yesterday still works today. In trouble shooting you must take nothing
for granted and establish one building block at a time until you reach
only one possibility left. Until it is established that it works on a
printer, it is still a possible cause of your problem.

So much for the pass through option. It is good to know that the
cables have not been moved however. That doesn't mean they are good,
just not connected improperly.

As suggested above, I would establish the parallel port functioned
properly on some other device. The CMOS settings should of course be
EPP or ECP (bi-directional) and not standard parallel port.

The lamp might come on by default, but it should come on when the
WATCH.exe is executed. When you load the installation software, this
command is installed in your startup list. My guess is the icon for the
scanner is in the bottom right hand corner indicating the scanner scan
software is started. In my computer I stopped the scanner software from
starting and created a batch file to start it only when I want it started.

Seeing the light on would indicate a couple things however: First,
power is getting to the scanner. It might not be the 15 volts that it
is supposed to be, but it PROBABLY is.

Secondly, it does indicate that some of the parallel port works if you
can control it as mentioned below. It might not be working 100%, but
some of it must be working.

If your light is on for the scanner, check to see if the scanner icon
is in the bottom right hand corner of your screen. Right click on it
and choose EXIT, YES. Did the light go out? Go to the WATCH.EXE file
and double click on the file. Did it come on again?

If so, you can control the light through the software.

If the icon for the scanner is not in the bottom right corner, the
WATCH program did not start. If is there, then start IPE.exe and go to
FILE, ACQUIRE, SELECT SOURCE and your scanner should be listed there.
Is it?

You are right, the light comes on by default. I used the batch file to
control the scanner and only plug in the power when I am about to use
it. The control of the light with WATCH.exe is valid however. Run the
test above and you should be able to turn it on and off.

Anything is possible, but I would not arrive at that conclusion yet.

True, but I just think the probability of a flipped software bit

I have no device that can use a parallel bus, other than my present
and past printers. I'd very much like not to disturb my present
printer USB connection and its USB driver, in order to run it on the
parallel-I/O bus; because my memory for tedious stuff is presently not
all that good and I get fed up with fussing with computer problems all
the time.

According to my BIOS Setup instructions, there is the choice of:

1. Output Only
2. Bi-directional (default)
3. EPP
4. ECP.

I think that matches what I've seen when accessing this setup. I have
always had my machine in its default mode, and my scanner has always
before worked fine in that mode. (Well, sometimes TWAIN screwed up
and I had to warm-start my computer.) I tried EPP, after the current
problem occurred, but that did not correct the problem, so I set my
BIOS back to the default.

I'm not sure what you mean by "default" here, but the bottom line on
the lamp is that whenever there is AC power into the power supply at
the scanner's plug, and the scanner power cable is connected to the
scanner, that lamp is ON, perior. It's always been that way, and
Mustek said it's supposed to be that way.

That's just for the lamp, right? The lamp is at its normal
brightness. I might be able to find a test point for the power bus
for the electronic circuitry, but I don't know what voltage that's
supposed to be and would hope a problem showing up there would be less
likely than a software problem.

Well, I can't turn it off. See above.

There is the file: C:\WINDOWS\TWAIN_32\A4S2_600\mtwm.ini that says:

LampStatus=1
GreenTime=15
ActiveTime=7352272

Is that a correct setup? If I set 'LamStatus' to '0' and save that,
the lamp still stays on. I have no idea what the other three settings
relate to.

The problem is probably due to the tsunami. Sick joke, here in CA.US.

You are probably right, but until you establish for sure that the

What I mean is even if NO software was loaded the lamp would come on.
Once the software is loaded for the control of the lamp, it should turn
off and on the lamp if you follow the procedure I described using WATCH.EXE.

The flags simply are stating that it did NOT see the scanner at the end
of the cable attached to the parallel port. This could be due to
several reasons, but one of them (power) is not likely since you see the
lamp lit. That would indicate power is reaching the scanner.

Other reasons could be corrupted software, bad parallel port or cable
from the port, or defective logic in the scanner.

The power to the scanner is used for both the logic and the lamp.
There is a regulator in the scanner (5 volt I think) that takes the 15
volts and converts it for the logic. The 15 volt input also is used for
the lamp through an oscillator that provides a higher voltage for the
lamp. Even it goes through a regulator, but I think it is a 12 volt one?

The lamp is at its normal
> brightness.


I would assume that your input voltage is good, since if it were low
the lamp would probably not light. This does not mean everything is
working on the scanner, but that the input is probably good.

If I were to guess, (and I don't care much for guessing) that is what I
would guess. For what it is worth, you could open up the scanner and
see if you can reach the two regulators. A simple DVM should allow you
to measure their output as they are both three terminal through-hole
components if my memory serves me. I agree however, that you are more
likely to find software or the port to be the problem.

This is probably due to the fact it cannot see the scanner. It should
have gone out if everything was working.

Since you do not want to test the parallel port (and I understand why),
removing ALL the software and reloading it is about all you can do.
Remember to delete the directories created by the current installation
so that no file such as the initialization files remain.

This is a little surprising in that I would have thought there would
have been no scanner listed there. Who knows, it might be placed there
even if it was not detected?

When I was working as a technician years ago, we used to say we were
about to call in an Indian to dance with feathers and beads when we
could not figure out the solution. Needless to say we did not do that,
but it is a little frustrating to have tried many things and still not
have succeeded. Rest assured, that the answer is there. You just need
to ask the correct question after having eliminated other potential
problems. It is NOT magic!! Look at it as a challenge.

Well, in its present condition, the lamp stays on no matter what.
When the scanner was working right, the light was always ON as long as
power was applied to the scanner. However, I never tried, at that
time, to see what would happen if I double-clicked Watch.exe.

I located two components on the main board that appeared to be power
regulators. I don't know their pinouts, but the only pins that
measured significant voltages other than 15 v showed 3 and 12 v,
respectively.

This file, in my case, now reads the same as before, except for a

Well, I have no idea how to get there from here. But I guess that
would indicate the problem is not hardware in the scanner. I don't
find any file by that name (with or without its extension) on the CD
for my scanner. Is it somehow generated during installation?

Where, in my case? As I mentioned, in my case, my BIOS is set to
"Bidirectional", not EPP.

I'm not really into challenges anymore. I suppose Mustek, either US
or Taiwan, would really laugh if I asked them how to make one of their
scanners bought in 1998 work. ;-) I couldn't find any answers to my
problem on the Web anywhere.

Incidentally, after Murphy got loose once and a bottle fell off a
shelf above this scanner and broke its glass, I had the glass replaced
at a glass shop, but the double-sided tape that held it didn't work
very well thereafter, particularly when I would place a heavy book
over the copy in order to keep it flat (the carriage even would hang
up); so I improved that flaky method of securing the glass with four
screwed-down metal clips. That totally did the job. I wonder if they
still use sticky tape for this purpose in Taiwan.

Attached is the install log (found in Twain_32\A4s2_600) of my last
installation. I see 2 failures, FWIW.

The reason it stays on presently, is the scanner is not recognized and
therefore the software (watch.exe) is unable to control the lamp. Since
the lamp will come one even if the scanner is not connected to the
computer, it will always be on. Remember, to make the lamp go OFF once
the icon exists in the lower right corner of your screen, you must do
the "Right click on it and choose EXIT, YES" routine. It is NOT working
that way now because the software is unable to see the scanner. The
software is loaded by virtue of the icon being present, and there not
having been an error message saying that a file could not be found
during the loading of that program.

One of the outside pins (the left one if I recall correctly, but don't
hold me to this) should be the input voltage. In this case, 15v. The
center pin is Ground. The right terminal is the output voltage, 12v.
You might not be placing your common lead of your DVM to true ground
when you measured the center terminal. Sometimes these circuits do not
use the same ground as your computer uses.

The other regulator should work the same way, but the output should be
+5v. (I think) The marking on the regulators should read something
like 9805 and 9812 indicating the +5 and +12 volt output.

If the software were NOT loaded properly, there should have been an
error message saying that a file was not found or could not load.
Nothing is 100%, but that would be the case most of the time.

The text I posted is NOT a new file, but part of the one you posted.
mtwm.ini I would think much of that segment is not in your file of the
same name due to the scanner not being detected. I simply pasted it to
show you more was needed in that file besides the segment you cited.

If your setting in CMOS is bidirectional, that should be FINE.
Different computers have different settings and verbiage. It is just
important that it is able to communicate both ways, and either EPP, ECP
or Bidirectional will do that.

Hell, they would laugh at you right after you bought the scanner. All
they wanted to do with me is sell me a scanner. Two of the shipments
arrived broken and I had one hell of a time getting it straightened out.
There is NO WAY they will help you with this scanner.

I sort of enjoy challenges, since I am retired and have time for them.
Even when I was a tech, I always viewed a problem as a puzzle. It was
like a game, in that the problem was hiding and my job was to find it.
True, there is frustration along the way, but it is also rewarding when
you succeed. You also become a LITTLE smarter in the process.

If I were you, I would first go back to your measurements of the
voltage regulators making sure of their values with respect to the
scanner ground. A good place to pick up ground would be on one of the
electrolytic's negative lead. If they measured properly, I would assume
your scanner was OK. Next since it doesn't sound like you will test the
parallel port, I would COMPLETELY remove the software and load it again
making sure the scanner is powered up while doing so. Be sure to delete
the directories created by the current load of the software, because
removal of software sometimes keeps files such as INI files. That might
screw up your next installation.

Finally, I saw your pasting of the install log in another message, but
the install log is probably of little value and hard to decipher. Try
the re-installation of the software as mentioned above.

Well, an email request to Mostek USA (automatically, I guess) got me
instructions on exactly how to pull all the twains and twunks and
reinstall new ones. Apparently I didn't have to uninstall the image
program bundled with the scanner, as I did before. The only
significant difference I could see between what these instructions
said and what I did before to remove this stuff (I still don't
understand whether their term 'scanner driver' refers to all these
twains and twunks or something else.) was that I didn't disable my
virus auto-protect program. Their instructions included getting a
different "driver" from their Website, which I did -- '123ep22.exe',
which came out in 1999. The one on my CD, that I used before, is
'd12epe22.exe'. Which one do you use? So I installed this newer
"driver". I note that it leaves out the 'Twain' folder, only
installing the 'Twain32' folder into the Windows folder. Isn't the
'Twain' folder just for 16=bit-word machines anyhow?

So, OK, now I don't get a flag saying it can't detect the scanner, but
I still get one that says it can't find 'twain.dll' in the Windows
folder, although this file IS in the Windows folder. So I guess I'll
uninstall that driver collection and reinstall the d12epe22 one per
their instructions and see if that works.

We can certainly forget all this discussion about when the scanner
lamp should be ON though. At present, when it DOESN'T say it can't
find the scanner, that light still does NOT go on and off with the
tray icon; it's ALWAYS ON. If it does in your case, it must be that
units having some ranges of serial
do that, while others don't.

I don't think there's any problem there. I measured with respect to
the INPUT power-cable ground. I measured the +12 and +3 on different
pins relative to the same physical start of pin count. The other
non-15-v pins on the two regulators had very low voltages. There are
no markings on the regulators.

Whatever. Software types have no constraints. It's all

They (SoCal, USA) did once when my lamp burnt out and I wanted to know
why it had to stay on all the time. Also, once when I downloaded and
installed something that indicated it was for this model but wasn't.
Maybe it was this very 1999 driver that isn't working for me.

Well, I got spoilt by playing design engineer. That was interesting;
trying to figure out why somebody ELSE designed something some
cockamany way never was fun for me. And software is pretty much
however you can hack it out, and it was far too serial for my mind,
even then -- and less memory-recording capability at present makes it
worse. I needed to get in from the side of designs and tweak them a
little (my stack was never that deep, for arbitrary stuff).
Collecting the results of fixing all that arbitrary stuff isn't my
idea of "smart"ness.

Maybe I'll check that AFTER I try the original driver again, loaded
exactly as per Mustek's instructions.

Rarely does the A/V program cause a problem, but if when loading
software does not give you the result you want, it is a wise thing to do.

I have used both of them, and I saw no real difference. I think my
current installation was from the CD.

So I installed this newer

Could be? I am looking at a Win 98 OS and that Dir IS there.

It is hard to say exactly why you got that message, but it sounds like
it is a path problem. It could be that some remnant left behind is
incorrect and it cannot find the file because it is looking in the wrong
location.

I doubt that. But it doesn't matter until we get your scanner working.
Then we will see if this is true.

Most of the time there are, but if you say there are not, then so be
it. You can generally tell what it might be by the voltage rating of
the caps tied to their output. That is, if the caps are rated at 10
volts, then the output of the regulator is probably in the neighborhood
of 5 volts. If the caps are rated 16-25 volts, the regulator is
probably no larger than +12. Most designers place caps with voltage
ratings approx. twice the voltage used on the bus.

Again, I cannot say with certainty that there is an isolated ground,
but I CAN assure you that the +3v is WRONG! If my memory serves me
right, there is a +5 volt regulator used for the logic. The input lead
was +12v if I recall, and the output MUST be +5v. The center terminal
is GROUND. If it is reading +3v, then either your meter is not on the
same ground plain or your ground lead has opened for the regulator.

There are very few semiconductors that operate at less than 5 volts.
In fact, the cut over level is generally recognized as 1.6 volts. That
is a zero is close to ground and certainly never over .6 volts. A one
is never less than 1.6 volts and normally close to the supply voltage.
(This is a GENERAL statement and depends upon many factors including the
type of semiconductor material.)

If you are truly hanging on circuit ground with your meter's common
lead and measuring less than either +12 or +5 on the output of these
regulators, you have a problem. Certainly the center lead on the
regulator is ground, and should read 0 volts.

Nothing lost. I can assure you however that those measurements if
measure correctly are wrong. Make sure you measure them with reference
to circuit ground. Which MIGHT NOT be PS ground.

To be honest with you, it is difficult to decipher exactly what all
that means. I will attempt after you take your voltage readings and
they prove correct. Error messages don't mean much if the hardware does
not work.

Top post because of so "stuff".

Your TWAIN.LOG shows that the TWAIN interface worked correctly.
I woud guess that the software is working and you have a hardware problem
with the scanner.

One other thing, If you have any virus software on your computer, Disable it
and remove all previous attempts to install. Then Install the software again
without the virus scanner running.

Here is a link for a graphic of the type regulator I believe is in the
scanner. http://www.nteinc.com/specs/900to999/pdf/nte960.pdf
I was wrong about the 9805 number, it is a 7805. (Had another brain
fart.) Notice however that the input voltage is on the left of the
device, ground is the center terminal, and the output is the left terminal.

My bad. [red-face emoticon] 7805 and 7812; see above. Not the first
time I've been a bad tech. I could blame my glaucoma, but it was
really lack of ambition to get the right tools.

The 12-v regulator is OK -- +15 v in, +12 v out.

The 5-v regulator reads thus:

The above circuit may be rather scrambled when you get it. Hope not.
The aluminum electrolytics, the regular and the resistor are all quite
hot, as is a nearby AIC 1563CN high-efficiency DC/DC converter.

I'm not sure how many of these components are bad. Maybe just the

Yes, you're right, a 7805 and a 7812. With the board out where I can
get a flashlight on the regulators at just the right angle, and using
a magnifying glass, I can read these old conventional numbers of
positive voltage regulators on them.

Ray,

I am not sure I am reading your drawing correctly, but if you mean you
have .5 volts on the output, THAT IS A PROBLEM.
> The aluminum electrolytics, the regular and the resistor are all quite

It will be very difficult to replace any of the logic circuits attached
to this +5 volt bus, but it is possible that a cap is leaking drawing
down your +5 volts. More likely, the regulator failed, but the only way
to tell is to lift some leads. I would first lift the output from the
regulator and measure it. If it is +5, then the problem is on the bus.
Using an Ohm meter and lifting leads from caps would be the next
easiest, then attack the other components if you choose.

For what it is worth, I repaired one of these scanners by replacing the
+5 regulator. Of course your results may vary!!!

Remember, if you do find it to be an electrolytic, you can replace it
with any voltage larger than the one installed and any capacitance
larger than the one installed. It is only a filter, so the capacitance
is NOT critical. Needless to say, observe the polarity.

There are, but they generally are more expensive than the +5 volt
variety. As circuits are designed to operate on lower voltages, they
are becoming more popular. This in turn causes them to become cheaper.

It really becomes quite involved to explain, but simply stated, the
circuits are designed so that stray noise does NOT trigger them. Since
noise is unavoidable in most cases, the threshold is designed so that
only a signal over .6 volts will switch on a semiconductor. Therefore,
most of the time a signal of less than .6 volts is considered a zero,
and one greater than 1.6 is considered a one. The area in between these
levels were referred in my day as "No man's land." That is, the result
of such a voltage was not certain on a circuit. One could turn on,
while another might not.

Disclaimer: News groups are famous for some person who has little to
contribute to a topic jumping in to contradict what another has said.
The topic of logic circuits is long and complex. It also has many
exceptions, and that is why I even hesitate to start to explain the
cross over level topic. I DO NOT HAVE ALL THE ANSWERS!!! Perhaps this
might negate the need for someone to blast me???

Yes, that's what I mean. And yes, that obviously is a problem.

Well, I overlooked a pair of tiny chip/surface-mount components on the
other side of the board, one on each side of the regulator to ground.
I would conclude they're either diodes or electrolytics. Do they
suppress high-frequency oscillations? They came after my
time-in-grade.

Anyhow, I yanked the two radial-lead caps and the regulator. All of
those appear fine -- as far as I can tell with a 20,000-ohm/v
ohmmeter. The chip jobby on the regulator input reads 3.3 ohm one way
and 20 ohms the other way (on the 20-ohms-at-center scale. The one on
the regulator output reads a dead short both ways on the same scale.
I assume the latter ist kaputt. Now, how the devil would I be able to
find out the specs of that component -- unless -- ha, ha -- Mostek
will tell me? Hey maybe they would send me a whole schematic. . .so I
could tell them how to make one that doesn't burn up, huh? I could
get a replacement mail-order chip thingy from Digi-Key, I guess.
Dunno what their minimum order is though.

BTW, the resistor I marked as 11 ohms reads 51 ohms cold. I said 11
ohms, because that seemed to be its color code -- but the first stripe
was a lighter brown than the second, so I was always supicious.
Apparently it used to be greeen. :-O

However, when I look at eBay or Craig's List, used and even new
scanners are a dime a dozen! I paid $133 (incl. tax and less rebate)
in San Francisco back in 1998. Craig's List has one of this model
(used of course) for $19 and eBay runs from $0.01 minimum bid on this
model, to $40 buy-it-now for a new, boxed-up Visioneer One Touch 5800
USB scanner. Is the latter any good?

By "yanking", I assume you mean the leads connected to the output have
been removed from the +5 volt bus and the short is still there? Or is
the short gone from the bus??

I am not quite sure what you mean by the "Chip jobby." If the
regulator has been removed, and the output lead on it is shorted to any
of the other two leads on the regulator, THAT is your problem. You have
a bad regulator.
If on the other hand the regulator has been removed and the short
still exists on the +5v bus, there is a short on the bus. Suspect caps
first, such as those whose leads you have lifted. If the electrolytics
have been lifted and the short still exists, look for SMD caps or any
semiconductor attached to the bus.

If we are talking about the +5 volt regulator, you can just buy one at
Radio Shack for a few pennies. Most of them are rated at something like
1 amp, and it is doubtful that anywhere near that current is being drawn
on that circuit. Take your old component with you and just buy a +5
regulator with the same physical characteristics, if that is the
component you are talking about.

Radio Shack. If you can't find one there, I will mail you one. That
is, IF THE REGULATOR is what we are talking about????

If this device is in series with the input voltage of 12 volts, it
might well be a coil (choke). Then the marking would not be ohms at
all, but milihenries. If you measured +12 with your DVM, the input is
OK. Your problem lies with the output.

Secondly, measuring a resistor while it is in a circuit often gives
false readings because of other attached components. The only effective
way would be to lift one lead and measure it. What is important is how
many ohms to ground the output bus reads.

On the other hand, if the component shorted is a SMD cap on the output
bus, then it can probably be replaced with one from a scrap circuit
board. This is not easily done, but I have done it many times. It is
true it might be for RFI, but it is probably not super critical. If you
can find another with similar makings, you will probably be OK.

Well, I see such being advertised in the Digi-Key catalog.

I mean these parts are sitting on the bench apart from their board.

Yup; from the trace to what was the regulator output, to what was the
regulator ground.

No.

The SMD. However, I was fed up with this nonsense at that point and
forgot there was still all the other stuff on that regulator-output
bus. So it's likely my conclusion that this SMD is shorted is wrong.

>If the
>regulator has been removed, and the output lead on it is shorted to any

>a bad regulator.

No, NO interlead measurement on the regulator, while out of its
circuit, shows a short. I have to assume it's just fine; but since
the trace that went to its output now still reads shorted to what was
its ground trace, if I want to pursue this silly game further, I
should check what's left connected to that regulator's output trace,
which still shows a short to what was its ground trace. If I got
whatever is shorted beyond that point fixed, perhaps I should check
the regulator unloaded or externally reasonably loaded to see that its
really OK, before puttin it back into its circuit on the board.

Yes, that's the case.

Right. . .if I want to further waste my time (which, I agree, is not
worth much at present. But it makes a lot more sense to buy a new
scanner.

Well, no, it's not! See above. Actually, though, I did first buy
adequate replacements for the regulator input and output radial-lead
caps and the regulator itself, the 7805. Radio Shack finally directed
me to one of their stores in this town that I didn't know of which
actually did have this regulator. I first went to two of their stores
and a local independent electronic parts store, all of which were out
of 7805s.

No, a millihenry choke would never drop the 4.5 v I measured across it
when the overloaded 5-volt regulator was in the circuit. I has to be
a resistor -- either linear or nonlinear with current.

NO! The input to the +5-v regulator is the +15 v from the plub
supply.

Well, something that's HANGING ON the output. I KNOW that.

Certainly, but I measured it AFTER I took the regulator and its input
electrolytic OUT of the circuit. Thus one end of this resistor was
handing free when I measured it at 51 ohms. Of course, it could be
half burnt up and thus not the value it was born with.

Right on. Thus I did.

Zilch (+\- what I can't see) on the X1-ohm scale of my mirrored 20,000
ohms/v meter.

Yes, I have a scrapped motherboard I bought for another part, which
board has at least 50 of the little things on it. Of course, I don't
know what size they are, but I agree the size is probably not at all
critical. I find it hard to believe this one's necessary at all.
There're probably others somewhere down the line on this same bus,
where they might make a difference.

Yeah. I could spend hours, maybe days yet, checking out all the parts
hanging on this +5-v bus. Just figuring out where it goes is no easy
thing. The board appears to be a 4-plane one that is not very
translucent. I should run my multimeter over the more than 1000 lead
terminations on this board to see how many are on this bus? Even my
life of upgrading my software and taking out the trash is more
satisfying.

It was certainly interesting to find someone who was so completely
wave-soldered into the exact scanner I was having trouble with, but
this trouble-shooting has gotten way past the limit of reason at this
point, I'm afraid.

Thanks for all your trouble though.
