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 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.
2906* Tailing Correction
2906 1
Shift value [0.0 to 1.0 / 0.0 / 0.1 mm/step]
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 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.
2906 2
Interval [1 to 10 / 1 / 1 page/step]
Changes the interval for the image shift specified by SP 2906 1.
2908 Forced Toner Supply
2908 1
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 the development unit reaches the
standard level, or for up to 2 minutes (whichever comes first).
2915* Polygon Mirror Motor Idling Time
2915 1
[0 = None / 1 = 15 s / 2 = 25 s]
Selects the polygon mirror motor idling time. 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.)
2921* Toner Supply Mode
2921 1
[0 = Sensor 1 / 1 = Sensor 2 (DFU) / 2 = Fixed 1 (DFU) / 3 = Fixed 2]
Selects the toner supply mode. Under normal conditions this should be set to "0". You can
temporarily change this to "3" if the TD sensor is defective. Do not set to "1" or "2", as these
are for design use only ( Toner Density Control).
