SOURCE: Install hp4600 dc controller

This is not exactly an easy task. But here are the step by steps
The following procedures explain the removal and replacement of internal components DC controller shield 1 Remove the following assemblies: ● Print cartridges and ETB.(ETB Is the black belt) ● Rear cover. ● Top cover. ● Rear top cover. ● Left cover. 2 Remove nine screws (callout 1). A tenth screw might be located on the rear of the printer at the bottom of the DC controller shield (callout 2). If that tenth screw is present, remove it. 3 Remove the DC controller shield. c0a7a70.jpg
Behind this shield is the DC controller board; It has quite a few wires connected to it, as it's the main controller for the printer.
1089df3.jpg Be sure to reconnect every wire or the printer will not work.
The correct Part Number for the LJ4600 (only) for the Dc controller is RG5-6391.
Good luck :)

Error code 52.0


A laser/scanner error has occurred

Recommended action:
1. From the DIAGNOSTICS menu, run the
laser/scanner motor component test.
Verify that you can hear the motor
rotate.
2. If you cannot hear the motor rotate,
verify that connector J1702 and J1505
are fully seated on the DC controller
PCA (ECU).
3. Verify that the connector J12 on the
laser/scanner assembly is securely
attached.
4. If the error persists, replace the laser/
scanner assembly

51.20 error message on HP laserjet 4250n printer


It is an error with the laser scanner unit
1 Press ( SELECT button) to continue.
2 Turn the printer off and then on.
3 Reseat the connectors between the
laser/scanner and dc controller
PCA (J83 and J84).
4 Replace the laser/scanner assembly.
See Laser/scanner assembly.
5 Replace the dc controller PCA. See
Dc controller PCA.

If nothing from above works and the printer is no longer in warranty, it is possible if the printer is being used in a very dirty or dusty enviornment that the lens and optics of the laser/scanner are so full of debris that the beam detect error occurs. You can remove the top cover and the big black box in the center is the laser scanner assembly. Remove the screws securing the top cover of the laser scanner and remove and clean up all the optics to include the main mirror in the front. I usually use a damp q tip and for the mirror I slide up from toner cartrdige shutter area and observe from the top as it cleans the mirror. Removing the complete assembly on this model is not easy since there are a couple of cables going to the dc controller which are difficult to remove so removing the top of the assembly is easier.
Here is the service manual:

Error code 59.c0 in HPLaserjet 5550


This means a printer motor error has occured. From the service manual: C developing disengaging motor rotation error.

To fix:

Developing disengaging motor
error
1 Reconnect the connectors J16 for the developing disengaging motor and J1100 for the DC controller PCB.
2 Replace the developing disengaging drive assembly.
3 Replace the DC controller PCB. Calibrate the printer after replacing the DC controller.

So, at the very least you'll need the developing disengaging drive assembly and, if that doesn't fix it, then you'll need the DC controller board. My bet is the DC controller has failed.

Sorry for the bad news, but please rate this solution as fixya even if it wasn't what you wanted to hear. Thanks.
