Canon ir C5030 Shading Black Text

I changed the Fixing Unit with a new one. Now the error is gone away.

Hello everybody,
The error is back. So slow really annoying. Meanwhile I have changed:
-the black drum
-ITB
-Fixing Unit

The error is not now on the entire page, but now affects only single letters which are printed in black.

Does one have yet another idea what can cause the problem?

Thanks for replies

You have changed everything but the black dev unit!?
What is the life showing?

[maximilian500]

The Developer have 45 percent life.

It's smel's like not enough black developer powder in the unit.Check values or replace black developer.

[maximilian500]

Thanks for the reply, I will replace the black developer unit with an new one and see then.

I have replaced the development unit Black and the error now disappears.

Hi there.
If you still have the old developer unit i'd suggest that you mesure or try to adjust the trimbar - the metal that adjusts the amount of developer that goes on the magnetic roll- just adjust it a little closer to dev.roll and try to see any difference. Sometimes the excess or lack of developer can cause this kind of shadow

Hello,
thank you for the tip. I will test this in another machine with the old Developer.
