You have a problem with laser unit.
From service manual:
when a laser diode (other then LDo) fired with the polygon mirror motor rotating at normal speed, an synchronous detection signal was not output within 250 ms.

solutions:
-harness connector of the laser synchronization detector board is loose,broken,defective
-laser synchronization detection board defectiv or installed improperly
-LD unit defective
-IPU defective
-BCU defective
