push down, slide out, pull tapes and fixtures off new unit(s) and replace. These IU's have chips in them to keep track of life. Another option instead of replacing the unit is to buy just the chip and replace it on the old image unit. This depends on the condition of the existing unit(s).

Possibly a dirty main charge wire on the black drum unit. Open the front door and locate a small light blue knob on the black drum unit. If you you pull that knob in and out of the drum unit it will clean the charge wire. If this doesn't you may hve to replace the drum unit.

something is blocking the LASER writing to the cyan drum, requires removing the cyan image unit and opening the protective cover of the LASER to clean the glass that it comes out of NO its not on with the image unit out and door open

in this model the IU units change not clean,because the drum is very sensibile.
