I have a client with a OKI C9650 that produces blurry images over only half the page.
Please see attachment image fault.pdf showing the top half of the document looking ok but as you look down the page, it starts to get blurry. Looking at the black block at the bottom of image fault.pdf, it is out of alignment with the rest.
On image faultb.pdf, there is very faint black text on the bottom right.
It seems to only happen on black. . .
I have replaced all the drums and toners, fuser and transfer belt!
I cannot find any firmware to update either.
All I can think of is replacing the black printhead which can be expensive!
Please let me know what ya'll think. .
Many thanks
