The drum cleaner consists of the cleaning blade, waste toner sensor (PS14), and waste toner
feeding blade.
The waste toner scarped off the drum is moved to the rear of the cleaner case by the feeding
blade, which is driven by the main motor. The waste toner case is monitored by the waste toner
sensor (PS14).
