2.5.1 Manual Image Density Level Factor
DarkerLighter
Manual ID level1234567
Change of grid voltage (volts)?0?0?0?0?0+50+50
The grid voltage does not change for manual image density levels 1 through
5. However, the exposure lamp voltage and the development bias voltage
does vary depending on the manual image density level. (See page 2-19 and
2-31.)
The grid voltage at the manual image density level 6 is the same as the one
at level 7, however, the exposure lamp voltage and the development bias
voltage are different. (See page 2-19 and 2-31.)
2.5.2 Auto Image Density Level Factor (SP34)
Auto image density levelData (SP34)Change of grid voltage (volts)
Normal0?0
Darker1-50
Lighter2?0
The grid voltage and the exposure lamp voltage are constant regardless of
the output from the auto image density sensor. Only the development bias
voltage varies depending on the output from the auto image density sensor.
When the auto image density level data is set to lighter, the change of the
grid voltage is 0 volt. However, the development bias voltage is changed -40
volts.
