HP LJ 5N Error 50

greetings all...

I need some information about the power supply in a HP 5N. currenty the system gives me an error 50, indicating that the fuser is not heating up. I hvae traced to broblem back teh the power supply, which dosnot give any power to the fuser.

I have found may dicussinos about HP II and III's having this condition, and I am inclined to aggree taht teh Triac in the fures cericit is gone. But all these discussions refer to a different board, and the componentnumbers dont match up, any one have a schematic for the Sony APS-50A power supple, or experience with this condition?? <img src="confused.gif" border="0">

YOu may have to contact sony or HP for that info. or wait to hear from Don J. he knows his stuff with printers

have you checked the support page for your printer <a href="http://h20000.www2.hp.com/bizsupport/TechSupport/Home.jsp?locale=en_US&prodTypeId=18972&prodSeriesI d=25479&prodSeriesName=hp+LaserJet+5%2Fm%2Fn+serie s" target="_blank">here</a>?

You are right, error 50 may mean a bad fuser or bad power supply. If you are not 100% sure that one or the other is bad, and as both components are rather expensive, I think it would be prudent to take your printer to a local authorized HP service center. (I'm sure there is one in Edmonton)

If you're sure the power supply is bad and needs to be replaced, then then you'll have to purchase a new one. Power supplies aren't user-serviceable.
