    Question Magenta Color reg. IRc2020 - fixed, but dazzeled...

    Had a magenta Color registration problem last Monday. I finally fixed it w/o parts, but it still has me dazzeled.

    Copy had white lines in magenta, so i did the usual, drum was brand new and ok, cleaned the laser and lines where gone.
    But after that magenta was off about 2 mm. Lines build up from magenta and cyan looked real bad.

    Did a color corection, no difference, took a closer look, and the magenta seemed to be off 1,5mm on the back and 3 mm on the front ! So i removed, cleaned and reseat the laser again, no difference. Did a Clear reg and color correction, still the same, reseated laser again, no diff. Did another clear reg and color correction, nothing.

    Did a clear reg, shut down, did another clear reg, then color correction (yes i'm subborn ) and it was just perfect.

    anyone a clue what has happened ?

    Hard to say...especially if color misreg was different at front and back of machine. I personally would clean the patch reader and reseat the itb. Chevrons are laid on the belt front and rear and patch reader reads them to correct laser for correct registration. Dcon clear would have been my next step.

    Sometimes it works when you shake the new drum-unit otherwise you can try with a piece of paper to clean the area between drum and skimming blade

    Thats was has me dazzled. I can understand mis.reg. and even cleaning the patch readers, spec. in a 20xx But never saw a difference in front and back of the print. My first thought was i misaligned the laser... But the printer was checked and fine 2 days before (changed Cyan an magenta drum then and did col.corr. and full gradation...)
