Sharp AR M155 Bad image quality

[Zoollanderhu]

Hi Everyone!
I've got a Sharp AR-M155, it has very poor image quality when the prints come out.
the whole page is quite dirty and the image is ghostly..... when I set the contrast lower it is better but still far from good ..so very bad.
I looked the drum's surface , nothing major problem and aslo the wiper blade, no problem, cause when I drive with my hands in reverse and in good way it clears the toner down.
Any idea what could occur?
What should I look for?
Laser unit? DV?
I just saw the fixing unit/fuser but it hasn't got and scratch....
I cleaned the both corona wire on the right opening door ( transfer corona; and the Drum's corona top of the drum.

thank you for your ideas and advices!

I've got already the service manual..but as a canon technician I'd prefer those people's advices who usually repair sharps.

Clean the optics and check the toner you use.

Few things can cause a ghostly image, bad fusing, bad cleaning, lsu...

Have you tried to stopped the machine while the copy was in progress and see if the problem occurs before or after the fuser ?

Hi
I think that you must confirm how many copy has the consumables, because if there are many copys, may be to the issue. New developer and drum/blad , fix the issue.
good look
