Print quality on iR ADVC 5030.

[Ingranaggio_rotto]

I'm here again !

I have a defect of print in a iR ADV C5030.
Specifically, in the prints with low-density colored backgrounds,
there is a lack of uniformity in color, with small white spots.
In each color !
This is visible in pg-type under value "100".
I changed drums, developing unit, iTB, roller transfer internal (by each color),
secondary roller transfer external and inner secondary roller transfert.

The defect is even present.

Suggestions ?

is it more noticeable on heavy or bonded paper? The new ITB belt is thinner and you have to adjust that in service mode. I know you say you have changed the ITB, is that the whole assembly?

Maybe you already did these :

1. Remove - clean - Insert the laser unit
2. Upgrade to the latest version
3. Do all the Image Quality Adjustment Procedures

It has been years since I've worked on Canon equipment, so I'm not sure about this.
But have you tried loading paper from an unopened ream into that machine? It could be the paper currently in the machine has a humidity problem.
That's just something that is more likely to show up on prints that have low density backgrounds from what I've seen.
Sorry if that was a waste of time.
