excellent, thank you very much .
960K55081 is for the lower speed of the machine (7525/7530/7535).
For your machine you can use both 960K55091 and 960K55092, they are equivalent.
Thank you, Gabi.

What's MD PWB is that Motor drive printed wire board?

Hi,
If the Developer Housing and Drum cartridge are ok, next step is to replace the MD PWB.
