Operation data
(Machine

Used to check the data on the result of
the image forming section correction
(process correction) (the corrected main
charger grid voltage in each print mode,
developing bias voltage, the laser power,
etc.)
(This simulation allows to check whether
the correction is executed properly or not.)

Operation test/check

Operation

Used to check the operation of the toner
motor and its control circuit. 
(Note) 
Do not execute this simulation with toner
in the toner hopper. If executed, excessive
toner may enter the developing section,
causing an overtoner trouble.  Be sure to
remove the toner motor from the toner
hopper before executing this simulation.
