6.10.5 TRANSFER CURRENT CIRCUIT
[A]: Transfer power pack
[B]: Transfer roller
[C]: Nip between drum and transfer belt
[D]: Drive rollers
The transfer power pack does the following:
• Monitors the currents I1 and I2
• Adjusts its output (It) to keep the current I3 constant, regardless of changes in
temperature or humidity which can affect the surface resistance of the paper.
A varistor [E] keeps the voltage at the cleaning roller constant [F].
