    Exclamation IR-2020 Faint line of output across page

    Hello all. Having an odd issue with our Canon IR-2020 - as shown in the screenshot, it prints perfectly fine except for a missing strip near the top of the page where toner is barely being applied. This affects both black and white and color prints.

    Things that have been tried prior to my taking over the issue:



    • Swapping all drums
    • Changing black toner
    • cleaning the laser glass
    • performing maintenance from the system options


    We have limited supplies on hand for this printer and would like to narrow down the issue before sourcing more parts. Did I mention this printer lives at a remote station in Antarctica?
    Any help is greatly appreciated, thanks!

    SWAPPED with NEW or USED?

    what about transfer roller/ITB?

    What is life on fuser?

    have you cleaned the PCR's? **HINT to follow**

    is there anything blocking laser beam? fuzz .. zoom?

    COLD could be a major factor ..

    we need more info Brother..

    could you post the first 5 pages from config report?

    Do you have the service manual?

    If what Phil posted checks out then next step is dump the old toner in Dev unit (mono componet, no developer used in this model)
    Then scrub mag roller with scotchbrite pad. Put NEW toner in developer unit. Check doctor blade, etc when you have developer unit apart to dump old toner.

    OK the hint.....


    look in the PCU at the Primary Charge Roller

    if you see a line or spots on the PCR:

    pull the PCR... take some Nu Finish car polish

    apply thin coat to PCR... clean the roller w/ soft cloth...

    buff it so it shines.. if marks are still on roller

    reapply and buff...

    when the roller looks good reinstall and test

    it should remove the marks and the print should be bolder

    Appreciate the replies all. This is a problem I inherited when I got down here and has vexed several of our techs previously. Balmy -14C outside today.

    What is life on fuser? Unsure, probably old. No record of swapping it in our maintenance log.

    have you cleaned the PCR's? **HINT to follow** We have not.

    is there anything blocking laser beam? fuzz .. zoom? Good question - will look.

    COLD could be a major factor .. The printer has been in a temperature controlled office ~ 75 degrees for the last few years. It IS extremely dry here however.

    could you post the first 5 pages from config report? Looked for a way to export / print this on the 2020 - haven't found yet. Will try again later today.

    Do you have the service manual? We do now!

    Environment switch (SW17)


    hello good night the canon printer is located in the antarctica ?? It is a place that is a very cold climate, you have to check the Environment Settings (ENV-SET) Temperature, humidity, environmental heater,
    condensation, acquisition of records.
    in the printer "activate the Environment switch (SW17)"

    Think I saw some mention of color in this thread, I was talking about the old B&W model. If this is a color model disregard my earlier post
