Blurred copies usually stem from a deteriated opc(drum)
to eliminate the optics, run prints directly, a management list is best, turn sub switch off, press/hold 3and6 while turning machine back on, press on screen, list print, management list, if these are blurred then change the drum, don't forget to do counter clear for drum, also in 36 mode. blank copies usually are down to poor transfer.
does the machine code at all?

I have never heard of a developer moving backwards!!!!!!!!!!!!!!!!???
the motor that runs it, the .... there is too much involved to mention. A developper moving backwards will spill so much toner in the machine anyway.
If you get a copy and then it goes blank, that tells me you have a problem with the SEPERATION UNIT, it may be shorting out causing the paper to rise against the drum giving you blank copies.
A blurr copy tells me there is a problem with the Scanner/Optics area. maybe the rails that the scanner run on are too dry or has a problem, the optics(mirrors) may be misaligned.
Not sure what you mean by (hanging) ??

I have no information on this fault. I suggest you contact the manufacturer directly with the question, but really doubt it will be something you can fix yourself.

Hp laserjet m1522f error 5 turn off and on


Hi, Error 5 is a Scanner error. When turning the printer on, have the lid up so you can watch the scanner movement. Does it move smoothly? It should go through a warm up and you should be able to watch the scanner movement. If there is a problem with the scanner, there isn't a lot you could do except. The service manual says the scanner assembly should be replaced. If it was my printer, I would try to take a closer look at the scanner assembly and check to see if the scanner unit is bound up somewhere, or maybe a drop of 3 in 1 oil on the scanner rails. Let us know what happens.
thanks
