2) Image Density Adjustment Factor (SP34)
Depending on the SP34 setting, the development bias and the exposure
lamp settings are increased or decreased during ADS mode.

1 Light –40 V 0
2 Dark +40 V 0
3 Lightest –40 V +4 steps
4 Darkest +40 V –4 steps
1 step = 0.5 V (120 V machines) or 1.0 V (230 V machines)
3) Manual Image Density Setting Factor
Depending on the manual image density setting on the operation panel, the
exposure lamp voltage is changed as shown in the table below:
