0V
25°C or lower +1V
If the temperature around the drum is 25°C or less when the main switch is
turned on, low temperature correction is applied to the exposure lamp voltage
as shown in the above table.
Under this condition V
R
data correction is also applied to both the grid bias
and development bias voltage.
4.7.5 Total Exposure Lamp Voltage
The total exposure lamp voltage for each mode is determined by the CPU as
follows:
(1) ADS Mode
Vexp(SP48) + Reproduction Ratio Corr V
L
Corr Low
Temp. Correction
(2) Manual ID Mode
Vexp(SP48) + Manual ID Corr Reproduction Ratio Corr

Corr Low Temp. Correction
(3) ID Sensor Pattern Detection
The same as the ADS mode or the manual ID mode depending on which
mode is being set for making the ID sensor pattern.
(4) V
