Phaser 850 using colour on black and white print runs

[JH]

Hi all,

I have recently purchased a Phaser 850. We print booklets. I print the
covers off which use colour and have no problems at all. I am pleased
with the ink usage here.

However when I come to print the 8 inside pages of the booklet (duplex,
then folded into A5), I am using colour ink when I don't want to be.
The inside pages have been generated from publisher and printed to PDF
in black and white format. They are mainly text buy contain some
grayscale images. I then print these 8 pages (duplex) using the
following settings:

Print Quality: Fast Color
Color correction: Black and White (I've also tried "None").

These are set on the driver and on the printer itself. Even with these
on I am still getting 1% coverage from each colour ink, which goes
through colour quite quickly when printing 8000 pages! I don't want to
be using any colour ink at all for the inside pages, but just can't find
a way to stop the printer doing so.

Another interesting stats from the "Usage Profile" is line 131 which
logs all my supposedly "Black & White" printoffs as "Color".

Can anyone help me to use black only for the inside pages?

Thanks
JH

There's your problem.

Publisher (and Word, and Powerpoint, etc.) is an RGB program. Your
printer is CMYK. Your RGB black has a formula of 0,0,0. When
translated to CMY for the printer, your printer or printer driver is
translating that to 100,100,100.

This is very, very common.

If you're making PDFs, you need to set the Distiller options for a
strictly black and white PDF, no matter what--if that's possible.

Publisher is rather problematic for things like this. Is there a
setting in your printer driver for "pure K" or "pure black" or something
like that?
