4) ATR SUBASSEMBLY CLEANING
Due to the constant pumping of developer through the ATR Subassembly, cleaning of the sub-
assembly housing is periodically necessary. Perform this cleaning as follows:
a) Wipe both walls of the slit molded into the underside of the ATR housing with Premix.
This is necessary to clean off the accumulated toner deposit.
See the Service Handbook for additional details about assembly cleaning.
