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.

4 Cleaning Adjusts the current applied to the transfer roller for roller
cleaning.
[–10 ~ 0 / –1 / 1
µ
A/step]
Increase the current if toner remains on the roller after
cleaning. (Remaining toner may cause dirty background
on the rear side.)

6.12.2 Image Transfer Current Timing
Forced Developer Churning 802
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.
[0 = No / 1 = Yes]
If the machine has not 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. After finishing, press the
!
key to clear the Vt value from the screen.
Tailing Correction
1 Shift value Shifts the image writing position in intervals specified by
SP2-906-2.
[0.0 ~ 1.0 / 0.0 / 0.1 mm/step]
When making many copies of an original that contains
vertical lines (such as in 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.
906*
2 Interval Changes the interval for the image shift specified by SP2-
906-1.
[1 ~ 10 / 1 / 1 page/step]
Forced Toner Supply 908
Forces the toner bottle to supply toner to the toner supply
unit. Press “1” to start.
[0 = No / 1 = Yes]
The machine continues to supply toner until the toner
concentration in the development unit reaches the
standard level, or for up to 2 minutes (whichever comes
first).
Polygon Mirror Motor Idling Time 915*
Selects the polygon mirror motor idling time.
[0 = None / 1 = 15 s / 2 = 25 s]
To increase the speed of the first copy, the mirror motor
begins idling when the user sets an original, touches a
key, or opens the platen cover or DF. If this setting is left
at the default (15 s), the motor will stop if the user does
nothing for 15s. If the setting is “0”, the motor will not
switch off during standby. (But note that regardless of the
setting, the motor will switch off when the machine enters
energy saver mode.)
