Previous
To prevent image quality problems owing to the instability of the leading/trailing edges of the paper when entering the nip of the PTR, the belt-to-paper transfer bias is adjusted for the leading/trailing edges.
Belt-to-paper transfer: Leading edge correction
Belt-to-paper transfer: Trailing edge correction
Belt-to-paper transfer: Length of area to apply correction at leading edge of paper
Belt-to-paper transfer: Length of area to apply correction at trailing edge of paper
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.
