Ok, this will cover number 2 and 3 above. a lot of 3rd party vendors ship the wrong fuser out. remove the fuser, check the white label, and make sure the part number reads RM1-1082 xxx. any other number, and you have the wrong fuser. also, place your original fuser back in. if you have the same error that your replacement fuser is giving you (and both have part number RM1-1082 on them), then replace the power supply assembly (RM1-1070-040CN), and if that doesn't work, then do a DC controller (RM1-1108-130CN). best of luck.

For the HP 4350 laserjet DTN what is the error code 50.5 fusion error tell me. Is it an easy fix?

You need to replace the fuser lamp (or ceramic fuser) and the thermistor.
If you can get the replacement parts, it's an easy fix.

Hp 4m shows service error 50


The service 50 error indicates a bad fuser assembly. You can get one on Ebay for less than $50. To replace the fuser just open the door on the back of the printer, inside you will see the fuser, unscrew the 2 screws and pull the old one out. Insert the new fuser and screw it down, power on the printer and you should be good to go.

I hope this helps, If so please rate our solution.
