Normal paper
2301 1
Adjusts the current applied to the transfer roller when feeding from a paper
tray. Use a high setting if the user normally feeds relatively thick paper (within
spec) from a paper tray
Thick/Special
2301 2 Adjusts the current applied to the transfer roller when feeding from the
by-pass tray. Use a high setting (a) if the user normally feeds relatively thick
paper from the by-pass tray, or (b) if waste toner is re-attracted from the drum
(which can occur when using transparencies).
Duplex
2301 3
Adjusts the current applied to the transfer roller when carrying out a duplex
job. Use this SP if there is poor image transfer on the rear side of duplex
copies.
