    I don't think so from what I remember, but I'm sure it would have helped. We started putting all machines on silent mode since the '02 series because of fuser issues.

    i have had same issue and asked KDC tech for help.
    take a look for the enclosed file and follow up the complete cleaning procedure at first.
    (i am not able to read japanese, so i got translated version)
    i would asked for data, but in cleaning in the right way solved the problem.
    To prevent further problems, i prefer to check/ clean all points each 300.000 pages.

    7002i / 8002i development unit problem

    Hi! We have 7002i and 8002i in one location and 7002i in another location and all of the machines have the same problem.
    The new development unit (or new MK) works pretty well until 30-50k copies, then toner dust starts to collect on development unit (and make toner spills on paper)
    we checked the toner dust "suction" system and filter unit on the rear side (even tried to remove filters), everything works and ther is no clogged toner in it
    we also vacuumed development unit, but this operation helps for another 10-15k copies. Toner is OEM.
    Any suggestions will be highly appreciated.
Working...
