Epson sc 740: how to select black ink in dos

Archived from groups: comp.periphs.printers (More info?)

I can't answer that specifically, but Epson printers need to have the
head filled with something (usually ink) to keep them from drying out,
unless they have been fully flushed of all ink.

If you were to clean the head fully and flush it, you could run a
totally empty cartridge in the color and then print with the black.

You may not have been printing with the color inks, all inkjets use up
some ink each time they are turned on (all the inks).

If you wish to use the color heads later, you don't want to leave them
without a cartridge unless they are cleared of all ink.

If, say the black print heads failed on the 740, could one fill a color
cartridge with black, and, after a time where the remainder of the color
ink flowed out, have a decent black and white printer (mostly for drafts.)?

I suppose what you could do if you wanted to use the printer for
printing something from a word processor, is fill a color cartridge with
black ink in all three chambers (Cyan, Magenta and Yellow). Then, when
you finish your document in the word processor, change the text color to
one of those three colors (a fully saturated Cyan, Magenta or Yellow
(which would be hard to read on the screen!)) and randomly use one color
on each document. That way, all the heads would get exercised, and be
kept from clogging.

However, as I recall, the black head on the 740 had about twice or 3
times the number of nozzles that the color heads had each, so the
printing process would probably be slower when printing from the color
heads, as I imagine more passes are required to form and fill out the
lettering.

Ah, makes sense. I guess that relegates my sometimes-maybe plan of
action into if-I-get-really-bored-and-want-to-muck-around status.
Thanks. You saved me some future grief.

PiErre,

You can get the Epson Stylus Color 740 to print using only black in two ways.

The first way is to use a DOS printer driver that supports the Epson "ESC/P 2" printer language. If you can download and install a DOS printer driver for any of these printers it should work: LQ-150, LQ-570+, LQ-1070+, Stylus 300, Stylus 400, Stylus 800, Stylus 800+, or Stylus 1000+.

The second way is to somehow write to the printer the five characters:

Esc @ Esc r 0

in a row, without the spaces. That last character is the digit 0, not the letter O.

You might create a five-byte file with those characters (let's call the file "black740.bin") and then copy the file to the printer, assuming your printer is on LPT1, with a command like "copy /b black740.bin lpt1" or you could write a very short program that will print those characters. For reference, those five character, in decimal are:

27 64 27 114 48

and in hex they are:

1B 40 1B 72 30

Immediately after writing the five bytes to the printer, either by running a small program or copying a file, print your output. It will print using only the black ink.
