This one has me puzzled. Customer prints prayer cards for funerals which has photo of the deceased. The photos have some faint streaks in direction of the paper feed. They have been doing this for years with this copier and was working fine until recently.
The Fiery & copiers internal test pages are good. Halftone test pages are good. Streaks only happen on photos. Tried several different photos from Fiery & just copier with USB jump drive and both show the streaks.
Replaced ALL drums, transfer belt, 2nd trans roller, fuser unit. Of course cleaned print heads with wand. Did gradation adj, etc. New transfer belt helped some but faint streaks still on half the page.
Only other thing I can think of is removing the print head laser unit and cleaning but why would the halftone test pages & other test pages be fine if dirty print head?
Any ideas appreciated.
Thanks in advance
