HP P2055DN - 52 SCANNER ERROR

[jtkaylor]

I have a P2055DN that I had to open up to remove an off-brand toner cartridge that came apart in the machine.

After I put the machine back together, when I powered it up, I got the error message 52 SCANNER ERROR.

I wasn't having this error before the problem with the toner.

I got a used scanner that was supposedly working fine, but after replacing, I have the same problem as before.

My next step is to purchase a new scanner, but before I do, I want to check to see if there is something I might be neglecting to do, if there is something else that might be the trouble that presents itself as a scanner error 52, or if there is some way to check to see if the scanner that I have is in fact good (or if my original, which I can sacrifice if neccessary, is good).

See the attached for connections to check.

Hi David - thanks for the help!

I disconnected and reconnected all of the numbered connections, and it still displays 52 SCANNER ERROR.

I guess my next move would be to get another scanner, but I've already spent $40 on a scanner that shows the same error for a printer that I could buy a refurbished one for $99, so spending much more on this seems a little silly.

Thanks for your help!

One more suggestion.  The error relates to the scanner motor which sits inside the scanner located in the rear. It sits on a small circut board and has a like chrome wheel. There is a wire from the circut board that attaches the small circut board in the diagram as number 2. Open up your old laser scanner as the just a few screws and clips and lift off the top. You will see the motor in the rear. Gently spin it with you fingers. Does it move smoothly. If not see if there is a clip which holds the shaft in place and if you can remove the shaft and clean off the part that goes back into the motor. You will then want to put a very very tiny drop of synthetic oil down the shaft. If you can see the drop you put in too much. Place the round piece back into the hole, spin a few times and put back the clip if it had one, put the cover back on and put in the printer as you can leave the top cover off for testing. Turn on and see if you get the error. I think there is a interlock for a shutter mech so you may just get blank pages with the top cover off but no matter if you get pages thru without the error you should be good to go.

Thank you again, David - I opened up the scanner housing and the motor seems to spin freely.

When I spin it between my thumb and forefinger, it spins several revolutions, so it doesn't appear to require lubrication, but I am not certain how freely it should spin.

I wonder if I somehow damaged something else when I took the unit apart that manifests itself as a scanner error, or if the used replacement scanner coincidentally had the same flaw as the original.

Thanks for your help!
