Canon Ir5000 Never Warms Up

[OtherTech]

Fuser never lights but no error code. Don't think relay is getting voltage to turn on. (ac is present at relay.) Weird thing is no error message. Main thermistor has been replaced. Not sure what it could be?

I would keep it simple, and check the rear of the Fixing Bed and made sure there is no paper lodged in on connector in the rear or that one of the connectors is not broken. That would stop the error reporting process and/or powering of your lamps. You will usually get an infinite "Waiting to Print" or "Reservation Copies Can Be.." message on the panel. Good luck. Let me know what you find.

I came across the same problem after 1 of my tech service the iR5000,what happen was after the tech service the transfer/seperation corona unit, when he is locking the unit lock,he accidently screw the wire of the corona unit cleaning which causing a short. Try check the corona unit.

Yes, the CONNECTOR on the rear plate was cracked. Sorry I took so long to reply. Thanks for the help

If the rear plate is ok, you can check under release knob from the front side have a one micro switch near the fixing unit. Good luck
