15.3.1
Toner collecting mechanism
• Waste toner scraped off by the cleaning blade of the transfer belt and that scraped off by
the cleaning blade of the photo conductor are conveyed by each of the toner collecting
screws into the drum cartridge.
A. Transfer belt
• Waste toner scraped off by the cleaning blade is collected by the toner collecting screws
1/2 for transfer belt.

15.3.2
Waste toner near full detection system
• Waste toner near full and waste toner full conditions are detected through the control
performed using the Waste toner near full sensor, toner agitating screw, and the internal
counter.
A. Waste toner near full condition detection control
• Rotation of the toner agitating screw causes the actuator to move up and down via the
float plate, so that the Waste toner near full sensor detects “H” and “L” signals alternately.
• When the amount of waste toner in the waste toner box exceeds a predetermined level,
the toner agitating screw no longer rotates. This results in the Waste toner near full sen-
sor detecting either the “H” or “L” signal only.
• The machine determines that the waste toner box is in the waste toner near full condi-
tion.
B. Waste toner full detection control
• The machine determines that there is a waste toner full condition when 200 images are
reached after a waste toner near full condition has been detected.
• The counter is automatically cleared to reset the waste toner full condition when the
imaging cartridge is replaced with a new one.
