(3) Developing bias voltage check
B. Mechanism section
Note: Use a digital multi-meter with an internal resistance of 10M or
more.
(1) Image position adjustment
1) Set the digital multi-meter range above 500 Vdc.
2) Put the test rod of the digital multi-meter on the developing bias
voltage output check pin.
3) Turn on the power, execute SIM25-1.
Note:In advance to this adjustment, the sub scanning magnification ratio
adjustment must be performed.
a. OC image lead edge position adjustment (SIM 50-1)
1) Set a scale on the OC table as shown below.
2) Make a copy.
3) Check the copy output. If necessary, perform the following
adjustment procedures.
4) Execute SIM 50-01.
Select a desired mode with the arrow keys, enter the adjustment
value with 10-key, and press [OK] key.
When [START] key is pressed, a sheet is printed.

1) Set the digital multi-meter range above 600 Vdc.
2) Put the test rod of the digital multi-meter on the grid bias voltage
output check pin.
3) Turn on the power. 
(The voltage is outputted in the grid bias High output mode during
warming up, and in the grid bias Low output mode when warming up
is completed.)
