SOURCE: I have error code 51 and 21 on the printer. I

21 is "Page too complex"
51 is "Beam detect error" or "laser error"

My question to you is, does this only happen when you are printing a page that is very graphics intensive, or does it happen with simple jobs too? It could be that you just don't have enough memory in the printer to handle some of these pages. Then again, you may have to replace the laser scanner. I advise you to call a tech out to take a look at it rather than trying to fix this on your own.

If it isn't happening too often I'd probably just **** it up and live with it if it were me. If it is getting in the way of business though you really ought to call a tech. A lot of times these things can be fixed for a lot less $ than you'd think.

SOURCE: HP Laser Jet 4 Plus error code 52

A 52 error is a Scanner failure. Do you hear a "whirring" sound when you get the error?

That's the sound of the scanner motor running amuck.

You're probably going to have to replace the Laser/Scanner assembly or the DC Controller which controls the Laser/scanner motor.

51 error code


That's a "beam detect" error. You probably have to get the laser/scanner replaced. Part Number C2037-69008.

5120 code error


Any of these error codes (51.20 51.21 51.22 51.23) points to a failure with one of the laser scanner assemblies on the HP Color LaserJet 4610 an 4650 series. To solve these error codes, replace the corresponding laser scanner. Sometimes when the laser scanner fails you will also hear loud noises (often higher-pitched noises like screeching sounds); the noises can be another sign that the laser scanner needs replacing.

The printer is showing error 51 and not printing


Control Panel message
51 PRINTER ERROR

Description

Beam error
Action
Laser scanner cable connectors are faulty or laser scanner assembly is defective Most likly it is the laser/scanner assembly. The motor is probably not spinning at the right speed. You would need to find an old hp 4 no longer working and switch the laser/scanner. It is the "black box" located under the top cover. You would need to remove the right side cover, the top cover, the left side cover and the output assembly. Remove all the cables from the scanner retaining clips. Remove the three cables plugged into the scanner and remove the four screws attaching the scanner to the frame. When replacing the scanner make sure the shutter control arm on the left front side of the scanner is attached correctly so that the shutter closes when the toner cartiridge is removed. You could first try to remove the 3 connnectors and reset them.
