Copies come out with a duplicate lighter image half way down the page

Hello Paul,
There are no "cleaning sheets" for this unit. Typically when this unit starts leaving marks on printed copies then it is time to do some maintenance on it. By maintenance I mean replacing the imaging drum, the toner and or the developer, all of which can be ordered from this link; Sharp Monochrome Copier Copier Duplicator FREE delivery If you don't feel comfortable then you need to call service!

need to replace transfer roller

I had replaced the fuser - no improvement. I removed the fuser, imaging unit & transfer roller. CAREFULLY using a vacuum cleaner I cleaned all units and the internals of the printer, rotating the roller on the imaging unit to clean all parts. (Warning Place Imaging unit on paper as toner escapes) After a few test prints the page cleared and duplicate ghosting cleared.

The duplication problem can be either the drum or the fuser. Most likely your drum needs to be replaced. If you can measure the distance between the first print and its duplicate I might be able to help more.

thanks adi

two things cause this problem the toner cartridge or the fuser 85% of the time its the fuser. check the rollers of the fuser for toner build up.
if you want to isolate it sent a print job that is 2 0r 3 pages when the first one comes out of the output bin open the front door this will stop the other 2 pages. 1 half way thruogh the fuser and the other halfway past the toner inspect the pages this will tell you exactly whats causing it

Do printed pages come out better than copies?
If they are the same, you may try another toner cartridge (especially if it is a remanufactured or compatible toner), otherwise, you need your optics cleaned (mirrors and lens under the contact glass)

replace drum blade

This can be caused by one of two things.

1. faulty wiper blade on your toner so that the previous image in not being wiped off the drum.
2. worn fuser sleve.

To work out which it is you will need to do a half stop test: print off a normal document then when it is about half way through the printer ( unfortunatly you may have to repeat this to get the timing right) open the front cover. remove the toner cartridge. if you can see the ghosting on the page the it is the toner. if its not there then its a new fuser. to save on money and if your confident enouh you may be able to just chane the fuser sleve depending on the state of the fuser on a whole.

hope this helps

I ran the hp toolbox "cleaning" mode too and it did not help the problem at all. I still have a dark smear concentrated in the middle of the page, and ghost images repeated lighter all the way down the page.
