3. High voltage adjustment
(1) Main charger (Grid bias)
Note:
●
Use a digital multi meter with internal resistance of
10M
Ω
or more measurement.
●
After adjusting the grid LOW output, adjust the HIGH
output. Do not reverse the sequence.
Procedures
1. Set the digital multi meter range to DC700V.
2. Set the positive side of the test rod to the connector CN11-3
(GRID) of high voltage section of the power PWB and set
the negative side to the frame ground (radiating plate).
3. Execute SIM 8-3. (The main charger output is supplied for
30 sec in the grid voltage LOW output mode.)
4. Adjust the control volume (VR-141) so that the output volt-
age is –400
±
20V.
5. Execute SIM 8-2. (The main charger output is supplied for
30 sec in the grid voltage HIGH output mode.)
6. Adjust the control volume (VR-142) so that the output volt-
age is 580
±
10V.
(2) DV bias adjustment
Note:
●
A digital multi meter with internal resistance of 1G
Ω
must be use for correct adjustment.
Procedures
1. Set the digital multi meter range to DC500V.
2. Set the positive side of the test rod to the connector CN-10-
1 (DV BIAS) and set the negative side to the connector
CN10-2 (FG).
3. Execute SIM 8-1. (The developing bias is outputted for 30
sec.)
4. Adjust the control volume (VR-121) so that the output volt-
age is –400
±
5V.
