1st transfer roller cam motor control circuit

The 1st transfer roller cam motor is a DC motor driven by the control signal output from the ASIC on the

LGC board and rotates the 1st transfer roller cam to contact/release each 1st transfer roller for Y, M and

C color to/from the transfer belt.

The motor driver outputs the drive signal (TBLTM1A-0A, TBLTM1B-1A) to the motor based on the con-

trol signal (TBLTM1A-0C, TBLTM1B-1C) output from the ASIC. The motor operates the rotation, stop or

brake according to the status of these drive signals.
