Ir1025 waste toner full/replace drum unit

[RHodg57]

i have been working on these for years and have not seen such a stubborn intermittent problem.

It gives the waste toner full message. New drum did not help. Replacing the sensor didn't work.

I changed the d.c. controller and it still gives that message. Had it inshop for a week and it worked

just fine. Anyone had this problem?

Try reforming and reseating one of the bias contacts that the drum uses.

The cover panel that surrounds the toner container has to be removed in order to access this area.
Once the panel is removed, the bias contacts can be seen. The bias contact for this issue has a black wire and white connectors (check red arrows below).
The bias contacts can also be checked with a continuity test. In this case, a poor drum bias contact was believed to have caused this issue. Check that the inner bias contact is not flattened.
