aper or

Adjusts the paper attraction roller current for color printing.
If paper misfeeds occur at the transfer unit in color mode, check and/or adjust the paper
attraction roller current.
NOTE:
The magenta development section is close to the paper attraction roller.
Decreasing the current may not cause paper misfeed.
If the current is increased too much, the following image problems may occur depending
on the humidity.
High humidity:
Insufficient image transfer in magenta due to current flow to the magenta OPC drum
Low humidity:
Offset image in magenta halftone areas due to paper charged positive too much
When adjusting the current with this SP mode, the value should be lower than transfer
current.
