    Sharp MX2640 Color

    Have this machine where when you would usually change out the MC - in this case the Yellow, that it would correct the bands printed out on the page. I changed the MC, the Drum, and swapped out the Drum itself to correct the issue - with no luck. The only thing I didn't do was change the Yellow DV or DV Unit. I didn't do this because visually the DV Unit looks okay.

    I spent the better part of a morning trying to work the fix but couldn't.


    Anyone run into this issue? Any suggestions? Greatly appreciated!

    Not sure which types of bands you are talking about but if it's not the drum or charge or the laser glass then my next step would be developer or the DV unit.

    Good luck.

    That was my thought. Out to see if that is the fix today. Thank you for the reply!

    Issue turned out to be a bad MC. I had changed each one of the MC's, one at a time. The banding never stopped. Worked it again this time with a whole Brand New Drum Unit and then the issue finally cleared - It ended up being the Cyan Drum Unit's MC. Go figure.

    Thanks to all responding!
