• 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.

PTR Rotation Speed

The PTR [1] has the function to deliver the paper from the paper transfer timing roller.

Since the paper transport speed is controlled by the PTR, if the PTR rotation speed is slower than the

target the image will shrink, if faster than the target the image will stretch.

A problem such as side-to-side image magnification misalignment and mottling on black half-tone parts

may occur in the printed image because of the speed difference relative to the image transfer belt. To

solve this problem, it is necessary to adjust the PTR rotation speed.

Since the paper is simultaneously gripped by the PTR and the paper transfer timing roller, uneven density

and banding problems may occur, if the speed differs between these rollers. To prevent this problem,

you can adjust the PTR rotation speed.
