To prevent image quality problems caused by the unstable condition of the paper when it enters the nip of the PTR, the belt-to-paper transfer bias is adjusted for the leading/trailing edges.
The following are the three bias correction settings that adjust the bias level and duration.
Belt-to-paper transfer: Constant voltage
Belt-to-paper transfer: Leading edge correction
Belt-to-paper transfer: Trailing edge correction
Current vs. Voltage
Bias is applied using 'constant current' for drum-to-belt and belt-to-paper transfer, as this method is resilient to changes in operational environment and thickness of the media.
On the other hand, 'constant voltage' is used for AC bias and as this method does not require adjustments according to paper width.
