    Canon IR-2220i Print Quality Issues

    I've got a Canon IR-220i - about 450k - all is good except that when I changed the Drum Unit - FB5-5020, the image quality was off-set - meaning, that the image at the Top was nice and Dark, and as you got lower on the page it became lighter and lighter. Put the Old Drum in and the Copy Quality is even throughout the Copy.

    Replaced the Drum Unit twice - same results. The Transfer Roller was changed (new), along with the Fuser Film(also, new). Tray Feed is all new. Made sure that the Glass & Mirrors were clean. Tried cranking the Image Density, nothing happening.

    Doesn't make a difference in quality whether running off the Glass, or thru the Doc Feed.

    Any suggestions? Greatly appreciated.

    Good suggestion. The Laser was cleaned, too - again, the Old Drum works fine, its when I put in the new Drum that I have an issue.

    CANON OEM DRUM ????

    Check if the image on the New Drum is Good/
    if good/Replaced the Transport Bed Varistor FF3-1173-000.

    The image from the Drum is not good. I have changed the Drum Unit twice - using OEM Drum Units.

    Tech2002,You said "I've got a Canon IR-220i - about 450k - all is good except that when I changed the Drum Unit - FB5-5020". The only number I have for the drum is Canon drum unit GPR-6 ,6648A004AA. Is that what you are using?

    That's very strange. You would think that it is a drum issue because the old one works fine. Have you tried either of the two new drums in another machine to see if they exhibit the same problem? Have you tried a working drum from another unit to see if it works? Let us know.

    Don't have another machine to use either way with the Drums. I am ordering still a third Drum Unit, coming in from another location - thinking that it might be a bad batch that I've run into with the current supplier.

    From the Old to the New Drum - it is night and day - The older having the better image quality.

    Go figure - I have never seen anything like it. Not unless it was a bad Drum in any machine I've worked on.

    Are these genuine Canon drums, or aftermarket?
