Function
Selects whether the FCI smoothing function
to remove jagged edges is enabled or
disabled.
FCI smoothing is only used with the Sharp
Text setting in text mode with binary picture
processing.
This is for the designer's test purposes.
Do not change the value.
Shifts the image across the page at the
interval specified by SP 2-906-2.
When making many copies of an original
that contains vertical lines (such as a table),
separation may not work correctly, then a
tailing image will occur (ghosts of the
vertical lines will continue past the bottom of
the table). This SP prevents this problem.
Changes the interval for the image shift
specified by SP2-906-1.
Forces the toner bottle to supply toner to the
toner supply unit.
Press "1" to start.
During this process, the machine supplies
toner until the toner concentration in the
development unit reaches a standard level.
However, if the toner concentration does not
reach a standard level, the machine
supplies toner for 2 minutes maximum.
Selects the polygon motor idling time.
If the user sets an original, touches a key, or
opens the platen cover/DF, the polygon
motor starts idling to make a faster first
copy. However, with the default (15 s), the
motor stops if the user does nothing for 15
s, and stops 15 s after the end of a job.
If set at "0", the polygon motor never turns
off during stand-by. However, when the
machine goes into energy saver mode, the
polygon motor turns off regardless of this
timer.
Selects the toner supply mode.
Normally, only use setting 0. Change to 3
temporarily if the TD sensor is defective. Do
not use settings 1 and 2; these are for
designer's use only.
