Motor speed is inconsistent.
Possible Problem
Solution
A. Loose wires
Locate power supply (Fig 1c). Check for loose or
broken capacitor/ resistor connections in cable
assembly (Fig 5a). If broken, replace assembly.
B. Optical Detector
Refer to 7.2.4. B
C. Timing wheel
Locate timing wheel (Fig 4a.). Make sure the timing
wheel has not changed location. This would cause

happened, change the optical board and realign the
timing wheel.
D. CPU Board
