2301* Transfer Current Adjustment
2301 1
Normal paper
[–2 = –4 mA / –1 = –2 mA / 0 = 0 mA / 1 = 2 mA / 2
= +4 mA]
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
( Image Transfer Current Timing).
2301 2
Thick/Special paper
[–2 = –4 mA / –1 = –2 mA / 0 = 0 mA / 1 = 2 mA / 2
= +4 mA]
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).

2301 3
Duplex
[–2 = –4 mA / –1 = –2 mA / 0 = 0 mA / 1 = 2 mA / 2
= +4 mA]
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 ( Image Transfer
Current Timing).
2301 4
Cleaning [–10 to 0 / –1 / 1 mA/step]
Adjusts the current applied to the transfer roller for roller cleaning. Increase the current if
toner remains on the roller after cleaning. (Remaining toner may cause dirty background
on the rear side.) ( Image Transfer Current Timing)
