Xerox and FujiXerox are not actually the same company, and they sell to different markets.
So the CM215fw isn't sold in north america, which is why it isn't listed on Xerox.com.
You may want to reach out to FujiXerox.
The information you are seeking would near certainly require you to enter into Service mode or diagnostic mode, which is not publicly disclosed information, so even if I had that information to share (I don't) I couldn't.
i have a docuprint cm215fw laser printer
the black was originally dense and solid
now it is faded and greyish, without the noticable sheen that the colour still has.
have cleaned everything
new cartridge
colour works fine
from the research that i have done, it seems that the black toner is not being pumped (augered) to the printer
I have read that a 'toner motor test with the cartridges still in (for black) generally solves this issue.
my question, how do you perform this test on a CM215fw.
there does seem to be an option for it in the normal menu system or the 'CE' service menu (hold up and down buttons on start)
please help or its a new printer
thankyou for your time : )
