[Current Paper Size] Transfer Current - Paper Size Correction
2-309
Paper Type -> N: Normal, TH: Thick, OHP
Corrects the transfer current for paper size.
When small paper is used for printing, the transfer current flows to the drum at the
non image areas where the transfer belt touches the OPC drum. This may cause an
abnormal image due to insufficient current at the image areas.
NOTE: Increase only when an abnormal image (insufficient image transfer) occurs on
a small paper size. However, increasing the current too much may cause
image offset.
