Transfer Current Adjustment
2301*
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 paper
Adjusts the current applied to the transfer roller when feeding from the by-pass
2301 2
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 (
Cleaning
Adjusts the current applied to the transfer roller for roller cleaning. Increase the
2301 4
current if toner remains on the roller after cleaning. (Remaining toner may
cause dirty background on the rear side.) (
Forced Developer Churning
2802
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
2802 1
been used for a long period of time, prints may have a dirty background. In this
case, use this SP mode to mix the developer. The message "Completed" is
displayed when the program ends normally.
Tailing Correction
2906*
Shift value
Shifts the image writing position in intervals specified by SP 2906 2. When
making many copies of an original that contains vertical lines (such as in
2906 1
tables), the paper may not separate correctly. This can cause tailing images
(ghosts of the vertical lines continuing past the bottom of the table). This SP
can be used to prevent this.
Interval
2906 2
Changes the interval for the image shift specified by SP 2906 1.
Forced Toner Supply
2908
Forces the toner bottle to supply toner to the toner supply unit. Press "1" to
start. The machine continues to supply toner until the toner concentration in
2908 1
the development unit reaches the standard level, or for up to 2 minutes
(whichever comes first).
