Procedure of
adjustment
There is no particular action required when the laser unit is replaced.
However, if the fixing temperature is 50 ºC or higher when the unit is powered
ON, electropotential control will not be executed.
Therefore, when the laser scanner unit is replaced and the fixing temperature
is 50 ºC or higher, it is necessary to enter the service mode described above
and perform forced execution of electropotential control.
