Ricoh c435 - White lines in Yellow

[matts5150]

Have 12k meter c435 that has 2 white lines in the yellow always in the same spot, all other colors are fine. Only oem toner used, have checked drums and transfer belt, everything is clean.
First time it happened at around 5k, it cleared up on it own after letting it set overnight. Now it's been this way for weeks, cleaned pdcu and glass under it, transfer belt is clean.
Any ideas?
Thanks

Clumps in the development unit blocking the doctor blade gap or toner build up on the back of the doctor blade. Use a doctor blade cleaner, check the Pro 1135 service manual for a part number to order doctor blade cleaners and instruction for use.

OEM does not mean the same as Genuine Ricoh or Canon or any other brand. It only means that it is made to the same specification as Genuine but not the same quality control.

Agree with both statements Slimslob made

It was clumps i the dev unit, is the developer replaceable in these or do you just have to replace the whole drum?

Thanks again!

You have to replace the drum unit on this model. Developer is not replacable.
