    [Misc] IR 6000 Three (3) Image anomalies

    Hello Folks! Trying to help a church out here. Giving them this giant.
    Runs great. Fuser good but noisy.
    Has three issues.
    1. Seems to have intermittent blur lines where the image is slightly crammed for a very brief second. There is no consistency to this. Could be 3 inches apart or six inches. Sometimes page is almost clean. Cleaned transport belts and registration roller. Noted one thing odd. Registration rollers (Timing rollers) have flat spots all around them almost as if they are made that way. Been in the business since 1986 and never saw this. The smaller Canons I do don't. Could this be the problem? (Lines go from Front of machine to rear.)

    2. A white or light VOID line going almost directly down the center of the page (Lead edge to trail edge.) Usually on Dual component brands this is just a bit of something blocking the developer brush: easily fixed. Does the Canon mono component roller have the same problem occasionally?

    3. This one I've seen before YEARS ago. A strange ambling row of blobs that are shaded as if there is a point of light off to the side resembling blobs of mercury. This is VERY random.

    See pick for all three anomalies on an old Panasonic test sheet.

    As I said, I'm trying to help out a bunch of good people.

    The registration roller would be a good bet, for the blurring,
    New charge wires should fix the light line , or check the developer roller for a similar pattern

      Yes I'd go for the registration rollers.

      Sort of-yes. It's unique to mono-component developing, and called "mottling". It's a hard build up of toner on the mag roller. Clean the mag roller with your green scrubbie. Also possible to get build up on the doctor blade.

      3. This one I've seen before YEARS ago. A strange ambling row of blobs that are shaded as if there is a point of light off to the side resembling blobs of mercury. This is VERY random.

      It's primary charge arcing. Replace the primary charge assy.
      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.
