iRC2880i bad copies

[iRC]

I'm having some issues with one 2880. The image is good when printing, but all copies are quite dark. Before I'm fitting a new scanner unit I must ask: Is there anything else left to do? I'm remembering that there is some adjustment at the service mode...

Thanks for the suggestions!

Great! That's what I was looking for. I'll try that on monday.

Teckat: The auto gradation adjustment is done several times; no luck.

Thanks Guys!

I recently had the same problem...did all that you did
as well. Only to find out the customer ran out of toner and was dumb enough to
put the waste toner back in the BLK toner ctg. What a friggin mess to deal with. Ended up replacing the Black drum unit.

Have you tried running a copy in each color ?

I've totally forgot to answer to this thread. Sorry about that!

My problem was cleared with the CCD -adjustment (lucky me). But it's nice to know that there's someone even dumber than me . I've never ever heard that someone has emptied a color copier's waste toner back to the cartridge. Oh no.
