P5 = Black imaging unit AIDC
P6 = Cyan imaging unit AIDC
P4 = Doesn't appear to exist???

Make sure the AIDC sensor windows aren't dirty. Also check for proper IU connectivity and make sure those connections are not dirty also. This could also require replacement of the affected imaging units and/or the transfer belt assembly.

The only info I got regarding that problem, could be it, could be something else, but definitely worth looking:

DESCRIPTION: Blank copies and prints.
CAUSE: A failed PWB-MC board.
SOLUTION: Replace PWB-MC (p/n 4036-7811-01).

I would remove the waste toner box,If it is very Heavy the icp may have blown on the main board and the dev from these units has been dumped in the waste box,
