Sir, i have hp laserjet colour printer CP5225, having error 55.0601. Kindly give me online solution


this all i manage to find for hope it helps

55.x Error
Error Message
55.X Error
Turn off then on
Description
The printer has experienced an internal error. The printer may experience one of the following errors:
55.0 DC controller communication error
55.0601 DC controller NVRAM data error
55.0602 DC controller NVRAM access error
55.1 DC controller memory error
Action
Turn off the power by using the power switch, wait at least 30 seconds, and then turn on the power and wait for the printer to initialize.
If a surge protector is used, remove it. Plug the printer directly into the wall socket. Use the power switch to turn on the printer.
If the message persists, contact HP support.

You need to first check the connection between the dc controller and the formatter and if the connection is fine you need to replace the dc controller.

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 :)

52.00 error


Hp says you have a bad scanner unit(laser unit) or DC controller, but first reseat all your connectors on your scanner unit(laser) and DC controller. Your scanner is located under the top cover and the DC controller is located behind the right cover. If the problem still persist replace the scanner first.
