HP Laser Jet III Printing Problem

Hello,

When I try to print a document, it gives me a 51 Error message. When I look at the troubleshooting in the manual, it says to press continue. However, when I get that message it then immediately goes to warming up. Then it prints a document that is just black lines, usually thick black lines. I pressed a button on the printer to print the fonts and nothing happens. Any suggestions?

Thank you

The error 51 is a loss of beam detect error.
The service manual recommends the following:
1. check the fiber optic cable for cuts or kinks.
2. replace the laser/scanner to dc controller cable.
3. replace the laser/scanner assembly.

Does it do this will all documents you print? Did this happen all of a sudden or after an upgrade?

Hello,

It does it sometimes. Then when I usually pull the toner cartridge out and put it back in, it seems to help.

This happened all of a sudden. I hadn't done any upgrades.

I agree with kenny...the LaserJet III is old. He's right about the DC controller board. It can be fixed, but who knows what else is going to go bad and at what rate. HP makes many deskjet printers that can rival the quality of the Laserjet III and they sell for under 200...get one of those and save yourself some money
