Pale horizontal line with small dots above it

[supportvsv]

Hey there,

I have a problem with the WorkCentre 7835, it prints on every single page a pale horizontal line with 5 or 6 small dots above the line. Here is an example picture:

I have already tried to clean the IBT belt but the problem persist. If R1 and R3 are switched, the dots become magenta and the line more visible. Here is a picture:

Can someone tell me where my problem is and how can I resolve it, please?

Thank you!

Hi,

If the issue moves to another color replace the affected drum (R1-R4).

First of all, thank you for the fast response.

So, if the dots are black before switching the drums and they become magenta after switching them, is R1 the affected drum?

If not, can you please tell me how can I troubleshoot this issue and find out the affected drum?

The affected drum is the one that was initially in position R1 when it was getting black dots, so that drum you must replace.

Thank you so much for the support!

Have a nice day.
