2301* Transfer Current Adjustment (
2301 1 Normal paper
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 paper
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
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
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 Developer Churning
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 like this, use this SP to mix
the developer. The message "Completed" is displayed when the program ends
normally.
2906* Tailing Correction
2906 1 Shift value
Shifts the image position at the intervals specified by SP2-906-002. When the
copier is continuously printing vertical lines (such as in tables), the paper may not
separate correctly. This SP can prevent this.
2906 2 Interval
Changes the interval of the image position shift specified by SP2-906-001.
