15.3 Operation
15.3.1
Waste toner box drive mechanism
• The waste toner box is driven by the transport motor.
• The driving force of the transport motor is transmitted to the registration roller via the reg-
istration roller clutch.
The drive coupling gear mounted coaxially with the registration roller drives the waste
toner box.
A. Execution timing
• The waste toner box rotates in synchronism with the registration roller. For the control of
the registration roller, see "Registration section".
15.3.2
Toner collection path
• With only the developing unit/K, part of the circulating developer is discharged into the
waste toner box through the toner collecting port located at the front side of the toner
supply screw/upper (auto refining developing system).
• For details of the auto refining developing system, see "Developing section".
