935 Service Print Error

935 - Mirror Motor unable to reach operating speed.

This error code indicates a problem with the mirror motor in the laser unit, the cable to the engine board cable or engine board itself.
Check the continuity of the mirror motor cable connected to J3 on the engine board.
If incorrect, replace the cable.
The voltage at J3-7 measures approximately +24 V dc.
If incorrect, replace the engine board.
If correct, replace the FRUs in the following order: engine board -> printhead assembly

Or you could try if a power cycle resolves the error (at least temporarily)

RICOH SPC430DN error sc202

sc202 is a polygon mirror motor. The most likely problem is that the motor has gone bad, and it will need to be replaced. Occasionally this error is caused by a loose or disconnected cable, but it is usually a bad mirror motor. You should contact your local service technician for replacement of the polygon mirror motor.

Sharp AR-M280U

L6-10 will be a polygon mirror motor error, (a multi-sided mirror that rotates in a similar way as a hard drive spins. writes laser data to the drum) .When this code comes up it usually indicates that the motor is locked. You will need a new polygon motor , most techs would change the entire laser unit.
Sorry but It will have to be serviced professionally.
