10.8 ADS SENSOR AUTOMATIC ADJUSTMENT (SP4-201)
When: 1. If the ADS sensor output voltage is not within
the adjustment standard after cleaning the
optics.
2. After replacing the following parts:
ADS board, Exposure lamp, RAM board on
the main control board.
3. If memory all clear (SP5-801) has been
performed.
Purpose: To make sure that the ADS sensor functions
correctly.
Adjustment standard:
ADS Voltage = 2.7
±
0.1V
How: SP4-201 adjusts the ADS gain value in memory
to get the correct sensor output.
NOTE:
Close the platen cover to prevent external light from reaching the
ADS sensor when performing this adjustment.
The adjusted ADS gain value and the sensor output can be
monitored with SP4-202. Refer to the SP mode table for details.
