    You can quick-check the PCUs by getting them out, shaking bit and turning all drums by hand a little bit back + forth a couple of times - this will put some "fresh dirt" on the cleaning blades and eliminate the noise (not for long, of course).

    with all process speeds? Does the MPC6003 use a discrete drive for dev or a clutch? Sometimes you must toggle several stuff simultaneously to get the parts really moving.
    I thing I also heard subtle noise from the dev units before so that's the next thing I'd check.

    My apologies friend, but I have been following this thread since your original post...perhaps it is just my advanced age, but I haven't heard a damned thing!

    It's the ITB unit-It's always the ITB,either the idle roller seized/about to seize in it's bearings , or the transfer rollers getting stiff in the plastic bushes.Have many devices do this,luckly had a account with 4 devices next to each other so swopped ITB unit over-sound transferred as well.

    thanks for your input!
