C. Transfer charger output check
1) Transfer charger current adjustment
1 Remove the developing unit, the transfer/separation charger unit,
and the main charger unit from the copier.
2 Remove the process unit from the copier.
When removing (attaching) the process unit from (to) the copier,
do not hold the toner transport pipe.
3 Remove the photoconductor drum from the process unit, and at-
tach the electrode sheet by using rubber ring and tape.
4 Attach the photoconductor drum with the electrode sheet attached
to it to the process unit.

5 Attach the process unit to the copier. (Attach so that the electrode
sheet lead wire extends from the developing unit side.)
6 Clean the transfer charger wire, and attach the transfer/separation
charger unit to the copier.
(Do not install the main charger unit.)
7 Connect the electrode sheet and the digital multi meter (or an
ammeter). Manually turn on the door switch.

8 Transfer charger output current check and adjustment
a. Turn on the main switch and execute simulation 8-02. (MTHV
is turned on for 30 sec.)
b. Adjust VR102 (MTHV output adjustment control) so that the
output current of MTHV is –41 ±4.0 µA.
