Hi, I was hoping you could tell me what to do when I have a fuser failure and the code u2 pops up on my Xerox Phaser 4500. The machine has not been in use for probably a year or so, what would you recommend I do? Thanks, Jeremy

For the 4500, the fuser part number is 604K28532, iteminc.com has them in stock for $205, or refurbished using brand new rollers for for $185. here is a video that shows you how to replace it. Very easy with no tools required.
From the Xerox Phaser 4500 Service Manual (here), the main problems could be one of:
Warm-up failure - Fuser warm-up not complete within 110 seconds after
starting.
Cool-down error - Cool-down process not complete within 200 seconds.
Low trouble temperature - The fuser temperature drops to the low trouble
temperature (approximately current control temperature, minus
approximately 25°C).
High trouble temperature - The fuser temperature rises to the high trouble
temperature (approximately current control temperature, plus
approximately 35°C).
STS circuit open
STS failure - The heat rod remains on for at least 10 seconds after warm-
up has completed
It could be that your fuser needs to be replaced, but as you can see that code relates to a couple of problems, so even replacing the Fuser might not fix the problem.
If it doesn't even do the warm up checks it is likely to be the fuser because the other components such as STS failure and cooldown won't have had a chance to run..
Error 928 refers to the fuser motor failing.
Problem could be with fuser motor, motor drive board or engine board.
One other possible cause would be if you are sending too thick a card stock through
the machine, this can cause drag on the fuser which the machine interprets as
a motor failure.
Hope this helps.
Fuser Failure, means that the fuser should be replaced.
