11.2.4.1.1. Control of Transport Motor
1. Paper Transport Motor for Finisher is of outer rotor type DC, brushless. Its control circuit is shown
below.
2. Pulse signals from P35 of P.C.B. (PWB-A) IC1 controls the speed. Signal L from IC1-P10 starts the
motor, while signal H stops the Motor.
11.2.4.1.2. Jogging Motor Control
1. Jogging Motor, which jogs papers in stack and carries out offset operation, is a two phase exciting type,
2-phase pulse motor. Its control circuit is shown below.
2. Each pulse signal output from Q1, Q2, Q3, Q4, of IC12 in P.C.B. (PWB-A) excites and rotates the coil
in each phase.
3. Motor is stopped when Q1, Q2, Q3, Q4, of IC12 change to Low signal level, and the power supply to
motor coil is cut off.
11.2.4.1.3. Belt Motor Control
1. The Motor for discharging papers out of stack is a two phase exciting type, 2-phase pulse motor. Its
control circuit is shown below.
2. Each pulse signal output from P20, P21, P22, P23 of IC1 in P.C.B (PWB-A) excites and rotates the coil
in each phase.
3. Motor is stopped when P20, P21, P22, P23 of IC1 change to Low signal level, and the power supply to
motor coil is cut off.
