802 [PA Cur. Size] Paper Attraction Roller Current - Paper Size Correction
Paper Type -> N: Normal, TH: Thick, OHP
Adjusts the correction, depending on the paper size.
When small-width paper is used for printing, the paper attraction roller current flows to the
non-image areas of OPC drum where the transfer belt touches the drum. This may cause
paper misfeed due to insufficient current.
To increase the current by 1.5 times, set the SP mode to "15".
NOTE: Adjust only when a paper misfeed occurs with a small paper size. Increasing the
current too much may cause image offset in magenta halftone areas.
