3.3.5 V
G
Correction
According to the drum rotation time after performing SP mode #66 when a
new drum is installed, V
G
correction is applied to the grid bias voltage as
shown in the above table.
3.3.6 SP Mode Data Setting
When the darker setting for ADS (data "1") is selected in SP mode #34 (ADS
density), the negative grid bias voltage is increased by –50 V.
When the lighter setting is selected, the negative development bias voltage is
increased.
