When printing black colors the image is not good. Developing unit is a new, fusing unit, transfer belt unit also, original toners.
Any suggestions?

run the halftone and gradation test patterns and determine if its an engine problem or physical issue.
what makes it classified as a Fiery issue?
what does the fiery demo page look like.
atdc levels? etc...
there are also a bunch of fiery color settings like black overprint composite black and the like.
have you changed the output settings on the fiery?

so many questions, can the copier produce a solid black halftone test pattern at 255?
just trying to see if its a fiery issue or a copier issue or even the paper for that matter.

I tried halftone on 255. The problem is the same, so not the Fiery is the problem. Tried different drum units - same.

image transfer roller?
I doubt, because its only on black.

As in any machine, half tone 255 and interrupt printing to see if the drum generates well, as you said that it appears the same when testing another drum, I would bet on the developer unit, counter?
