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.

I am getting scanner error 5 massage on hp 2840


A tech needs to look at it. It could be as easy as just reseating the 4 wire bundle connector that comes off the scanner and connects to the formatter.
But, in any event a tech has to check it out.
