Sharp mfp and quality problem

[Jack79]

Hello

I would like to kindly ask you to look at the picture and explain what may cause this problem. It is A4 printer (Sharp 381) and it prints marks on the page (long edge).
It looks like dirt inside the machine but I am not sure what should I clean first.

Till now I change (from other machine) fuser, black dev/drum, primary transfer belt.

at first glance I would say primary belt but you said you replaced it. stop machine mid print and check drums,belts, fuser etc.

That sure looks like a primary transfer belt to me.

I put tc1 belt back to the first machine and it has the same problem so probably primary transfer belt cause this problem.
Second machine showed c4-00 error when I wanted print a page and paper jams before fuser. I inserted primary belt (from first machine) and c4-00 has gone.

Is it any sim which I can perform to clean primary transfer belt? I do not have service manual for this machine.

No sim for cleaning the primary transfer belt. You will need to rebuild or replace...

Good luck and Happy New Year
