Strange problem with Ricoh mp7500

[Mark Bbb]

How about clogged ozone filters, or a failing cooling fan?

Bad airflow equates to excessive heat and static.

That would explain why it performs better with the door open.

Ozone filters tend to be a VERY overlooked maintenance item.

+1 !!!

Tried without filters and with out back cover still problem

You write in your first thread: "I must reset it with 107 off and on"
Which SC code appears than?

I think :
OR paper is stucked for a while under the drum, OR the movement of the drum or development roller is interrupted.
Do you hear a certain noise when it happens?

There is no special sound. The machine stops as if it wants to do a self check. Then the next sheet gets stuck. If I remove it, it keeps getting stuck until I reset it

Check 7-403 for internal errors. Could be cleaning web motor, or corona cleaner motor.

There is no error code, but i dont think that can be a problem, i have 10 machines with unplugged charge corona cleaner and they work well.

A printer sometimes stops at regular intervals for ID check, is this the case?
Or is there another reason why it stops? Perhaps to load toner?
I think that is the cause of the problem.
Perhaps a grounding problem?
