Checking & Adjustment Of Hvp3 (Transfer Corona) - KIP 9000 Service Manual

4. 3. 3 Checking & Adjustment of HVP3
(Transfer Corona)
The standard values of current supplied from the HVP3 are specified for each media type as
follows.
Plain paper 1.4mA +/-0.02mA
Tracing paper 1.4mA +/-0.02mA
Film 1.4mA +/-0.02mA
NOTE
A DC Current Meter must be connected directly to the HVP3 to measure the HVP3 output
current. (Multimeter is not able to measure the intensity.)
CAUTION
It is very dangerous to check the Transfer Current as the DC Current Meter muse be
connected directly to the HVP3.
For the safety, put a thick insulation pad such as urethane form under the DC Current Meter,
and also use a high voltage lead wire.
Check and adjust the HVP3 in the following way.
1. Remove the Drum from the machine for the safety.
The Drum will be damaged if not removed!
2. Disconnect the connector that exists on the cable between HVP3 and Socket for the Transfer /
Separation Corona. Connect "+" of the DC Current Meter to the cable from HVP3, and connect
"-" to the cable from the Socket.
Put a Urethane Pad under the DC Current Meter for your safety!
