15.3.2 Waste toner agitation control
• In order to avoid detecting an incorrect waste toner amount, the agitating coil is set in the
waste toner box so that waste toner can build up evenly in the box.
• The agitating coil is driven and rotated by the waste toner agitating motor.
• The waste toner agitating motor lock sensor detects the waste toner agitating motor lock.
A. Operation timing
• The waste toner agitating motor operates when the TCR sensor performs an automatic
adjustment, toner is forcefully replenished, and the transfer belt is driven.

15.3.3 Waste Toner Box-in-position detection
• The waste toner box set sensor is provided to detect a waste toner box loaded in posi-
tion. Timing for this detection is when the power switch is turned OFF and ON, or the
front door is opened and closed. If the waste toner box is found to be out of position, the
machine inhibits the initiation of a new print cycle.
