My printer is Hp Laserjet P2055d fail to work error 52 occur and display scanner error whwat can I do?

The laser scanner speed is incorrect. X description: 1 = Scanner startup error 2 = Scanner rotation error

Probably Resolution : 1. Press GO.
The page containing the error will automatically be reprinted.
2. Turn the printer off and then on.
3. Re-seat cables to the laser/ scanner and engine controller.
4. Replace the laser/scanner.

I might as well tell you before hand, I'm Not sure if yours can be repaired but on older models I have repaired them by opening the laser/scanner assembly and removing the little circuit board with the motor and chrome spinning shaft. If you can remove the chrome piece from the motor you do so and then place a very tiny drop of synthetic oil down the shaft, install the chrome piece and spin a few time by hand and put everything back together. You can download the service manual by doing a google search. Look for instructions for removing the laser/scanner.

Why do I get 3 groans during calibration accompanied by a 51.2m error ?

51.2 is a laser error.

there should be another number after the 2,

0 = black laser

1 = cyan laser

2 = magenta laser

3 = yellow laser.

The groan is most likely the polygon motor has lost its lubrication and may just need to be cleaned and re-lubricated.

You can also try reseating the connectors from the lasers to the DC controller PCB...

2. Replace the magenta print-cartridge drive motor.
3. Replace the driver PCA. 186

My hp laserjet 4600dn is showing an error message 51.2k

I finally got the courage to keep going, and got the laser/scanner out. I swapped it with the Magenta laser, and sure enough, the same error came up with M instead of K. So, I got ready to order a reman'ed laser/scanner, and was just about to click "checkout," when I figured I'd tinker with the bad scanner. I took it apart (I know, no user serviceable parts), and spun the laser by hand. There was the screeching noise! So, I removed the motor board by removing the 4 screws and the cable, then took some light oil, and a toothpick. I dropped the slightest bit of oil on the spindle on the top, and on the inside where it spun on the spindle, and spun the laser around by hand a few times... Then I inverted the assembly, and spun it around some more. Then I reassemble the laser/scanner module, cable, and then cover. I put the l/s back in, and with everything off, turned the printer on, forcing it to go through a cold reset. And sure enough, I've got my printer back!

HP 4600 printer with error message 51.2M and loud noise when calibrating. Any solution?

Replace your magenta cartridge first. If the problem persist I strongly recommend a service tech. Error 51.2M is an magenta scanner(laser) error or DC controller.
