Thank you.
Have any of the thermostats on top of the fuser jumped?
It's 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.
Hit it.
so far they are all intact.
Have you checked continuity with a meter.
We had this issue before and noticed that the connector for the whole fusing/exit assembly has a small paper that obstructs it. It was caused by a paper jam that the customer didn't remove properly.
Aye! Cut the crap
thanks i have checked all the connectors and theres not obstruction. the rollers do not also turn at all. no visible activitity in the fuser section.
I have encountered bad connector blocks. When the fusing unit is installed, one or more pins will push back out of the block instead of making contact.
Also, since the error is a rear thermistor error, check the harness for that thermistor.
