Laserjet 5N "Fuser Erro: Cycle Power" Message

Jan 27, 2013 3:45AM PST

I'm hoping someone can give me some insight here.

I have two HP Laserjet 5N's, one to use and one for parts. These are AWESOME printers and rarely break.

About a week ago I got the error message: "50 Fuser Error: Cycle Power". I swapped the Fuser from the other printer, and still got the error message. Then I swapped the big power supply on the bottom from the other printer: Same error message.

A few questions:

1) Is there a difference between a High-Voltage Power Supply and a Low-Voltage Power Supply?
2) If so, does my HP 5N have one of each?
3) If so, can someone send me a procedure and repair instructions on how to locate and replace the Low-Voltage Power Supply on an HP Laserjet 5N. The one I replaced is apparently known as the High-Voltage Power Supply. (Diagrams or schematics or pictures or even a video would be helpful.)
4) Also, is there someplace online I can download a FREE version of the HP repair manual for this unit? If so, could someone send me the link?

Thanks Very Much,

But I just let HP fix those things. We get so many years that if the repair comes back at more than the printer we get the new printer.

There is a web site called fix your own laser printer that may have more for those that want to dive inside a printer.

Actually, I did find that website and have now fixed the printer for free, and learned a few things in the process.

I prefer to fix things myself, which I did here at no cost. When these printers are working right, they run for a year w/o a checkup for the cost of about a $30.00 toner cartridge that will run 8000-10,000 copies. My kind of printer.

Thanks, Though,

I hear you.

We don't let our printers go for long without a maintenance cycle. That is we pull the carts out, paper trays and get the canned air over the usual places then put it back. Paper dust is a lot more damaging than most will write about.

Good you found that other site.
