    Drum get dirty also after new cleaning blade

    Hi, its an ira8105
    Even i installed new drum cleaning blade, drum get dirty after a large print.
    The upper side of cleaning blade gets dirty in the upper side, causing a dirt on the drum always. Maybe its missing some vibrating but wanted to know first because i dont have any replacing part to test.
    So i have to buy, but want to be sure,
    Any help?
    Thanks

      Check the drum cleaning assembly, some gears are known for not driving each other properly, see if you can turn the auger gears by hand.

          The auger in the cleaning assembly on the process unit(drum unit)...the shaft breaks at the front where the gear slides on. Magnetic roller turns but its rotation is not transferred to the auger, to move the toner out to the rear, to waste drive assembly, then to bottle. If the mag roll isn't turning, it could be in the waste drive assembly itself. It turns the little gear at rear of drum unit. Fun to replace the cleaner assembly...lol. Waste drive is easy. I've had both scenarios

              I faced that problem before and everything is perfectly working, small main gear in the back side, gears in front, auger.
              Maybe the blade its not genuine!

                      Try adjusting spring tension on cleaning blade holder. Ive seen that many times on Canons with selenium drums
