    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,
    CharmedLife417

    Hi, really appreciate the quick reply. I will check this out in the next 24 hours. However, this error message popped right away, even after the printer was turned off for 24 hours. But I will take a look, and thanks again.

    You may need to reset it as outlined in the manual.

    EDIT: I used to work for a copier/printer repair place, and usually when this happens that the error needs to be reset. If not then the printer is detecting either a heat issue or the sensor is not working.
