Purpose Adjustment/Setup/Operation data output/
Check (Display)
Function (Purpose) Used to check the data related to the image
forming section correction (process correc-
tion) result (corrected main charger grid
voltage, the developing bias voltage, and
the laser power voltage in each print
mode). (This simulation allows to check
that correction is performed normally or
not.)
