I have an HP 2840 and I have constantly been getting a scanner error 52 code. Per the text and research they say power it on and off, which did not work. Other experts say to replace the scanner assembly, which I did go and buy one, but I cannot find online anyplace that shows you how to fix them.

This printer has the rotating carousel assembly and therefore it is susceptible to becoming misaligned very easy and this could be the source of your scanner errors. More than likely of an inserting the wrong cartridge into the carousel...it can be fixed but judging by the age of this printer and the amount of labor to repair I would just junk this because of the time and labor involved ..plus there are definitely more productive and efficient models for a very low cost that will do you some justice.. that's just my opinion.

Scanner Error 52 is a hardware error. If turning the power off , waiting 30 seconds and turning it back on does not solve the issue the the scanner assembly might need to be replaced. Another thing to try is make sure the printer is plugged into the wall not into a surge protector. Aside from that you may need to have the scanner assembly replaced.

Based on the service manual the Error: Scanner Error 5 doesn't exist. However 52 Scanner Error exists. If the scanner doesn't function anymore the recommended solution is to replace the scanner assembly.

I noticed that this was posted in Oct 2010. If you are still waiting for an answer,
the printer has a scanner error. Power off for about 30 seconds. Power on, if
error persists, the scanner assembly will have to be replaced.
I hope that you got it fixed by now!

Recommended action

1. Verify that the connection cable is not loose or damaged. Replace the cable if necessary, and try the scan again.

52 scanner error means yoy got got an error with the scan assy, it could be many problems. If it not helps with turn off /turn on, try reset the printer. Turn off power press and hold * and #, turn on power, wait 20 sec and release the buttons. If printer not goes to ready, disconnect power cord when printer initialize and turn off power switch. reconnect power cord and turn on power switch. If you get the printer to ready state, upgrade firmware.

when poering on this HP 2840 it says" Scanner Error 5"
what does it mean? How to get a solution?
