Tr Current Adj (
"Image Transfer Current").
2301 1
Normal paper
[–2 = –4
A / –1 = –2 A / 0 = 0 A / 1 = 2 A /
2 = +4
A]
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
2301 2
Thick/Special
[–2 = –4
A / –1 = –2 A / 0 = 0 A / 1 = 2 A /
2 = +4
A]
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
A / –1 = –2 / 0 = 0 A / 1 = 2 A / 2
= +4
A]
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.
2301 4
Cleaning
[–10 to 1 / –1 / 1
A/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.)
2802
Forced Develpr Churn
2802 1
Initializes the developer and checks the TD sensor output (Vt). The machine
mixes the developer for 2 minutes while reading and displaying the Vt value.
The machine does not initialize the TD sensor output. If the machine has not
been used for a long period, prints may have a dirty background. In a case
