    7135 vs 420 drum and developer units

    Anyone know if you can swap the Drum Assembly, complete, and the DV assembly from a 420 to a 7135? They look the same, but are sensors within the same?


    Thanks!

    the 7145 is similar to the 420, not the 7135.
    you can cheat like i do and search consumables on precisionroller.
    if the part#s are the same i can cross but from what i see if the pics are accurate they are physically different.
    here is a sample Konica Minolta bizhub 420 Drums
    Konica Minolta 7135 Drums

    they take different developer too. the 7135 uses 301k and the 420 uses 511k
    We know a thing or two because we've seen a thing or two.
    The medication helps though...

      Another good trick is to download the full Parts Pricing List from Konica, then look up your part number. It's a quick way to get a list of machines that use the same parts, as well as finding updated part numbers ("NLA - Use ____ instead").

        Drums on the 7135 vs 7145 are different, the ends of the drums in which the shaft goes thru are different, over the years I have used and cross used the toners/developers for those machines, from the 7020's to the 7145's, no issues. When using the 7020 dv in a 7145, the c/q is rich and very good solids for over 100k.

            No, those are not. Very different.

                FYI: I swapped DV unit and Drum Unit Assembly from 7022 to 7135 and it worked perfect. Only mod was swapped Toner Sensor on bottom of DV unit!
