Brush Motor
Drive Circuit
The cleaning brush motor is a DC brushless motor. Controlled by the
CPU on the mechanical controller, it is used to drive the cleaning brush.
Upon power-on, door-open/close, or cleaning of the density detection
pattern after image quality stability control, or after the paper is sepa-
rated following every 100 prints, the CPU sets the cleaning brush motor
drive signal (
TDCON) to “L” to drive the cleaning brush.
