mpc4500 adding tonr

[spaceman99]

Each time u open any door I get adding toner. Sounds like its from the blk toner. replaced pump, dv assy, drum, irf pcb. Cleaned pipe and toner hoppers. Still getting it. No spillage in mch. mch works fine after it thinks its loaded.

Sounds like its from the blk toner.

Narrow it down to which unit is at fault. You can't troubleshoot a problem unless you KNOW for a fact which unit is causing it.

Then check the RJ45 connector on the back frame and the unit. They have been known for getting damaged when installing the units.

Thank you for your reply.
It is the black toner that is trying to load.

Maybe a dumb question, but did you try another toner?

I have a similar problem - machine is loading toner after every closing the door etc., but in addition ... in SYSTEM STATUS you can see toner bottles are full although they are empty actually. All colours.

Have you tried upgrading/reloading firmware?
