more while the laser remains ON.
- Check if the BD PCB, laser driver PCB and DC
controller are connected properly.
- Replace the BD PCB.
- Replace the laser scanner unit.
- Replace the DC controller PCB.
E110 The rotation of the laser scanner motor is faulty.
0000 The constant speed rotation signal (LM-RDY)
does not arrive for 20 sec or more after the
laser scanner motor (M4) drive signal has been
generated.
