I purchased a Canon MP730 today (04July15) and have been playing with the
software provided with this machine to fax documents directly from my PC.
This is a really cool way to fax something, but I can't help but wonder if
some upgrade is available for this software. Something that would allow me
to specify resolution for example? For example, if I fax a page from a
magazine with photos and text, the arriving fax is a bit hard to read, and I
think it is because the fax resolution is too low.

A couple of possibilities here.

If about the text, magazine text fonts are usually on the small size, and
larger fonts are always better for fax. You can help readability by
selecting Fine resolution. Fine is higher resolution than fax Normal
resolution, but still not very high, it is just that Normal is lower. And
the default is Normal resolution unless you select Fine. Normal is for the
purpose to be smaller and faster to transmit over the phone line, for a
cheaper long distance call. Normal sends only every other line of pixels, so
Fine takes twice as long to send, all else the same.

Not all fax machines can receive Fine resolution. Old inexpensive machines
may only receive Normal regardless what you try, but fax machines sold in the
last few years surely can do Fine. And the plain paper machines today print
better quality than the old ones too. But that is not true of all fax
machines, which you normally have no clue about, so if you are composing
something in a word processor to be faxed, be aware it may be received at
Normal resolution, and use at least 12 pt type for absolutely everything.

If you are determined, you can increase the size of the magazine text (any
scanned image) by manipulating to send partial pages. For example you scan
no more than half fax page width and half fax page length at double
resolution, 400 dpi line art mode, and then scale that image back to 200 dpi,
which will double the printed size of that smaller portion, back to be full
fax page size, but enlarged to double size. It doesnt have to be double
size, any proportional increase, but the final scaled page must not be larger
than the regular page size the fax can receive and print.

If it is about the photos, and if the photos have any importance whatsoever,
you should instead scan and email the files, instead of using fax. Fax is
200 dpi line art by design, designed for text. But fax is the absolute pits
for photo images, and email is usually readily available. Fax is simply not
designed nor suitable for photo images.

Fax is really old now, and not up to todays standards, but is still used.

The may depend on the receiving fax and how
it handles grayscale.

What are you faxing to?

FAX machines have fixed resolution. I believe that they are limited to something like
(example from an older Brother FAX machine)

Standard FAX 200 dpi

"Fine" FAX 400 dpi

"Photo" FAX 200 dpi with 8 step grayscale!

The standard (200 dpi) setting will look a bit 'rough,' and the 400 dpi 'Fine' setting may
help. See if your Scanner/FAX software has a setting for 'Fine.'

If that's not clean enough, you'll have to send an image file ... JPEG, PNG, or TIFF ...
and instruct your recipient on how to use a viewing program such as IrfanView, SlowView
.... or even Internet Explorer (only works for JPEG files).

For some time I have had an internet fax account with www.maxemail.com, and
I'm testing my MP730 by faxing documents to that account. I know from past
experience with this internet fax account that it can deliver quite detailed
results.

1. Click below for source image as scanned by MP730 and imported directly
into Acrobat 6.0.
http://www.petersale.com/images/scans/t300dpi_gs_source...

2. Click below for fax that was scanned and faxed directly from MP730 fax
machine
http://www.petersale.com/images/scans/hi_rez_fax.tif

3. Click below for PC fax from Acrobat source material in item 1 above.
http://www.petersale.com/images/scans/mp730_fax2.tif

3. Click below for PC fax of source JPG image in Photoshop that was as good
or better than PDF image in item 1 above.
http://www.petersale.com/images/scans/mp730_fax1.tif

In any case, when I fax a document directly from my PC I would like to be
able to specify the same sort of parameters (Standard, Fine, Grayscale,
etc.) that I am able to specify when I fax a document directly from the
MP730 machine. Might there me some sort of Driver or Utility upgrade that
will allow me to do that?

BTW, what brand and weight of bond (not photographic) paper provides the
best results with text and photos (real estate brochures) from my new MP730?

Hi Wayne,
My original question was whether or not I could upgrade the PC Fax driver
that got installed along with other software when I installed my Canon MP730
on my PC? I was hoping that an "upgraded" driver would let me manually
specify Standard, Fine, Grayscale, etc. fax resolutions. Well, I faxed your
thoughtful reply to my post to myself (www.maxemail.com) by "printing" your
post to the Canon MP730 fax "printer". The very nice result can be viewed
below:
http://www.petersale.com/images/scans/word_fax.tif

Actually, you need to save the sauce and then view it with "Windows Picture
and Fax Viewer" to enjoy the full quality of this fax. In short, it seems
the MP730 fax PC driver usually does a splendid job of automatically
setting the appropriate resolution settings, at least for this Outlook
Express document, and also for jpgs "printed" from Adobe Photoshop. My
problem was that a b&w resolution was chosen by the fax driver when I
attempted to "print" to the MP730 Fax driver from within Adobe Acrobat.
Click below to see what I'm talking about.

What I wanted was more like the following

but with fewer "dots."

Yes, printing a text source file directly to the fax software is always
better quality than printing it and then scanning it to fax.

All three of your images are 200 dpi line art, which is what fax is. Fax
simply does not know about grayscale. However the one image appears "more
grayscale" because the software created halftones, scanning first in
grayscale and then (because fax requires line art) converted to halftone
patterns of black or white line art dots that similate grayscale, in the same
way newspaper and magazine photos print grayscale using only black ink in
halftone patterns. More black dots is darker gray, few black dots is lighter
gray. You can see this halftone pattern better if the TIF is viewed on the
video screen larger than 100% size.

However the low quality is because the screen for fax is only 200 dpi, where
magazine screens are usually 2400 dpi, so there will be huge differences in
the detail and quality. Fax is simply very low resolution, designed for
speed on the telephone line and cant compete in most other ways. Fine
resolution is "full" 200 dpi resolution, and Normal sends only every other
line, effectively 200x100 dpi. A few fax machines do offer proprietary 300
dpi modes, often called Super Fine, but this is only useful to other similar
fax machines when you know they can do it, and is not usable in the general
case. That telephone time is also 9 times longer than Normal.

If you scan the image in grayscale mode, the fax software has no choice but
to convert it to line art. Often this is done with halftones, but sometimes
simply by threshold, which is the difference in your two cases.

Possibly more than you want to know, but you can convert grayscale images to
lineart halftones manually in Photoshop yourself (so that you have full
control of results), and then simply print that halftoned line art image to
the fax software. Photoshop menu Image - Mode - Bitmap (bitmap means line
art to Photoshop). Then if for fax, Output Resolution is always 200 dpi, by
definition of fax. Then Method is Halftone. Next dialog Frequency, 33 to 45
lpi will likely give your best results for fax. More Frequency lpi gives
more detail, but fewer shades of gray. Less lpi gives less detail, but more
shades of gray. It is a big tradeoff, and which is best depends on the
individual image, if detail or graytones are most important.

Specifically, Resolution/Frequency 200 dpi / 40 lpi = 5 pixels per halftone
cell, or 5x5 halftones, or 26 shades of gray, which is nearly acceptable
sometimes. 33 lpi is likely better for fax in many photo cases, but 45 lpi
may be better for graphics. But if you have photos, fax results are doomed
anyway, and it is much better to instead just use email, why beat yourself
up? It seems a lost cause.

Fax doesnt have to use halftones for this. The other bitmap Methods there
like Dither or Threshold can be excellent too, sometimes better for fax, esp
Dither. All are ways to simulate gray tones with line art density patterns
of black dots. Examining results at more than 100% size will help understand
it. Some fax software does this grayscale to halftone conversion
automatically, with one fixed set of values for all cases.

The resolution of fax is very low, too low for photos. Magazines probably
use 2400 dpi Resolution with 133 or 150 lpi which is 2400/150 = 16 pixels, or
16x16 cells for 256 shades of gray. Detail AND graytones. But 200 dpi isnt
much today, however it works for text.
