1. Process section
A. High voltage output adjustment
(1) Developing bias output check and setup
1) Remove the rear cabinet to allow checking of the high voltage
monitor output pin.
2) Execute the simulation of the target high voltage.
(See the table below.)
3) Select the mode to be set with 10-key, and press START key.
4) Enter the set value with 10-key and press START key. The set value
is outputted for 30 sec.
5) Apply a high voltage tester between the measurement pin and the
frame.
Note: Take care not to short the measuring pin and the frame.
6) The unit stops after 30 sec of output.
