(3) Toner replenishing control
• The toner replenishing time (the amount of toner supplied) during the toner replenishing control is determined based on the TC ratio
detected by the TCR sensor (noncontact magnetic type) disposed at the developing section of the imaging unit for each color of toner
and the amount of toner to be consumed (estimated) for the image to be printed.
• If replenishing is interrupted by a paper misfeed, the front door opened or closed, or any similar event, the required replenishing time is
carried forward to the next replenishing control sequence.
• For details of the TCR sensor, see Toner density control.
