Customer upgraded his machines but want to keep one of his old BH-C-280 for B&W mono copying and printing only.
I know that one can adapt the operation panel display for copying in K only and also there are K only drivers but he wants to be sure that nobody ever can make color copies and prints with this machine.
Question: Is it possible to limit this C-280 to B&W only? Any mysterious soft switches making this possible unknown to me?

If it was me I would put a password on it and default that to greyscale only print and copy. Job done…
Still machine will eat color toners and drums slowly. Calibrations are unavoidable.
Other than that you can go password/user authentication way or just like you said plus I would prohibit USB print.

You can put the printer as preferred black and hide the option in DIPSW.Originally Posted by Hansoon
Nothing like day after day
Replace CMY toners with K (change caps), after ~200 A3 prints, you've got B/W machine
Did you tried this personally?Replace CMY toners with K (change caps), after ~200 A3 prints, you've got B/W machine

Had to laugh first, cause sounds funny, but are you serious.........?Replace CMY toners with K (change caps), after ~200 A3 prints, you've got B/W machine
Cannot imagine that the calibration pattern being only in in K on the TB will be accepted by the logic of the machine. Furthermore operating costs are not only coming from toner use but also the drum and developer being used.

Paper and electricity.

That was just for fun and confuse
No, it will not work (at least in this machine | there are other ways for this machine), but not for the reason you think of:
> only in in K on the TB will be accepted by the logic of the machine
IDC sensors are color blind, they just measure density of the pattern, and doesn't matter what colour the pattern was printed.
So the important thing is location of the pattern (there must be toner patch in correct location on TB) and its density.
You can change the order of color developing units to prank somebody, but remember to block toner pipe (to not contaminate with other color) and make only few copies.
All K toner will not work for this machine, because of difference in develping units build, and conposition of the toners.
Black toner has additional developer mixed, for developing unit life extension, so there is a difference in developing unit (and waste toner box) for developer recycling.
Color developing units was designed for much shorter life, so they doesn't need recycling pipe and additional developer mixed with toner.
Without developing unit modification, the additional developer would kill them in short period of time.

The easiest (and not funny at all) way is:
- set [Image Stabilization Priority] -> [Black]
- set DipSW to hide Color option for copy
- use B/W driver from Bizhub 224 if you don't need user authentication
or
- use normal driver, set B/W for default
- block color prints for authenticated users

So the "density" of a K patch will be the same as for a Y patch???

This was not my intention ofcourse. I do this occasionally for testing purposes

Yep, I got that

Where to find which DipSw. And yes I'm stupid and on top of that lazy too.....
- use B/W driver from Bizhub 224 if you don't need user authentication
The driver is the easiest solution and has been done here for years.
or
- use normal driver, set B/W for default
On all our machines we install at least two drivers. One for color, one for mono and often too for duplex and letterhead also
- block color prints for authenticated users
I HATE the configuration for that authentication stuff. Did I tell, that I'm not only stupid but lazy too??
Thanks for your input.
