Canon iR ADV C5250 - Quality problem ONLY Bk Color

**luis1984bol** · 12-30-2019

Hello dear friends:

I have a quality problem with a iR ADVC5250 maquine.Only the black color is very poor as you can see 20191230172742.pdf

I had chanched the Bk developer but after a month the problem was back (white copies and impresions). Then I added the STARTER in the Bk develop assy but after some weeks the problem was back again. It seems that the maquine is consuming the starter.

I had clean the ITB unit, change the Bk drum, clean all laser units, checked the contacts of the High Voltage and checked the ATR Sensor also.

Do u have any idea about this?

Thanks for your help!!!...
