Suggested Solutions
1. Check the Beam Detecht signal. If there is
a BD signal, replace the Main board. If or
not, check the LD contol signal.
2. Check the LD Power is normal.
3. If it is normal, check the light receving part.
Check the LSU motor noise. If there is any
dirving noise, check the motor signal.

Replace the memory.
Check the ITB waste toner is eliminated
properly. If the ITB waste toner overflows,
the motor error will be occurred because of
increasing the torque. Replace the developing
unit.

Take out and Shake the developing unit
horizontally. And reinstall it. If the problem
persists, Replace the developing unit.
