Question about Office Equipment & Supplies
This is from a canon service manual -
Main Cause The BD PCB is faulty. The laser unit is faulty. The laser driver PCB is
faulty. The wiring is faulty (short circuit, open circuit). The DC controller
PCB is faulty.
0001 In 100 msec after the laser drive signal has been generated, the BD
signal is not detected 50 times or more within 40 msecs.
0002 While the laser is on, the BD signal cycle is found to be outside a
specific range 10 times or more.
I'd be inclined to check the laser out first, starting with checking the cable connections.
