Problem
The polygon mirror does not normally rotate.
When entering the input check, the polygon mirror is ON.
The polygon mirror driver outputs the signal which indicates the stability of the polygon mirror rotation.

Laser Synchronous Sensor Synchr
onous
When the polygon mirror is synchronous and
either of R/G/B laser or all lasers is/are emitting
Asynch
ronous
When the polygon mirror is asynchronous
When the polygon mirror is synchronous and
either of R/G/B laser or all lasers is/are not
emitting
When entering the input check, the polygon mirror and R/G/B lasers are ON.
When either of R/G/B laser is not emitting, it depends on the timing of measurement and the laser light intensity whether
synchronous or asynchronous appears.
When checking for any problems in the laser output, check with the output check.
