• The spent toner is conveyed by Spent Toner Feed Rollers 1 and 2 to the Recycling Duct
and eventually back to the Developer Mixing Chamber.
• To prevent paper dust from being compacted on the edge of the Cleaning Blade, the PC
Drum is turned backward as soon as a copy cycle is completed if the drum has been
driven for more than a given period of time.
✽
Given period of time: 35-cpm copier = 170 s; 25/20-cpm copier = 240 s
