GP 9.3 TRANSFER VOLTAGE
CHECK
PURPOSE
The purpose of this check is to ensure that the
Transfer Voltage is within specifications.
NOTE: You must have a High Voltage Probe to
perform this procedure
Note: During normal operation the Transfer
voltage will be one of two voltages (1500 volts
for plain paper, and 2800 for transparencies.
1. Set up the multimeter to read 1500 VDC.
2. (Figure 1): Connect the High Voltage
Probe to the Transfer terminal (black wire,
