    Cyan as a grid on 9060 Pro

    Hi Fellas,

    I have a strange case on a 9060 PRO.

    All drums and developers are almost new (just 5% usage).

    The problem is that cyan comes out as some kind of grid.

    It is not visible on the PG-5 though.

    But when customer prints on thick paper it is visible.

    I have already switched drums between cyan and yellow - and it is the same.

    I have also switched to ON the heater on the back of machine.

    What can it be ?

    Hi!



    You probably already tried gradation and calibration ......
    Any differences If you stir cyan developer?

    Yes I tried gradation & calibration a couple of times.

    The funny thing is that when I print calibration sheet on thick paper - the cyan degrades very quickly and in a grid filling.

    The other colors look fine.

    PFFFFF

    I am starting to have bad feelings about this series ....

    Did you try many of the Canon remedy settings:


    - Increase the developing assembly stop frequency: Level 1 > Copier > Option> FNC-SW > INTROT-1 > from “200” to “50.”
    - Change the TD ratio limiter table: Level 2 > Copier > Adjust > DENS > LLMT-PT > from “0” to “1” (Affected color only).
    - Increase toner discharge amount at time of low duty job: Level 2 > Copier > Option > IMG-DEV > DEVL-VTH > from “1” to “2.”


    Also inspect cyan tranfer roller.

    Hi Z,

    I went back to that customer and did all your suggestions.

    Nada...

    Even if transfer roller was in great shape - I still replaced it.

    Developer is almost new - 5 % on counter and also visually it looks perfect.

    Any other ideas except replacing dev unit ?

    Thnx...

    Was the cyan print quality with the old developer the same? Was the procedure for installing a new developer correct? Are the developer values in normality?

    Try with:

    copier>function>install>td-ac for all or only cyan.

    Had the nearly same Thing Time ago; try to change the Laser Units (I would suggest Yellow against Cyan) and see if the Error goes along with the Cyan Unit
