If it helps someone....
I was fixing a problem with the carroussel solenoid, and, because to test it , you have to assemble the machine again,i decided to try to put the machine working without covers. The error code 52 showed up almost imediately.Reason? I pressed the "cover closed" switch but forgot to press the locking laser mechanism (a lever at his right side). Beeing working with copy machines all my life, i remembered that even a dirty mirror can cause the same problem ( its called LD,Laser beam detect). The lever interrupts the beam.
Im specialist in Ricoh but i do all the other machines too.
So, even a tech man can make mistakes, rsrsrs...
NOTE!!! Dont you dare to look inside the machine directly, This small lasers can do eye damage.

Unfortunately there's not a lot you can troubleshoot with a 52 error. As it implies it's usually the scanner bad. It sits up top- under the top cover. It connects to the Formatter Board on the left side. and there's 2 connector s at the scanner itself.

Hp 2840


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 5 on HP Color Laserjet 2840


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.

Hp color laserjet 2840 error 52.


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!
