Mode Number/Name Function/[Setting]
909* 4 Printer – Long Edge
Feed Adjusts the main scan magnification in printer mode
when the machine feeds the paper in the long edge
feed orientation.
[-0.5 ~ 0.5 /
0.0 / 0.1%/step]
Margin Adjustment for By-pass 910*
Adjusts the blank margin at the trailing edge of paper
fed from the by-pass table.
[-9.0 ~ +9.0 / 0.1 mm / 1mm/step]
ID Adjustment for Test Pattern 913*
Adjusts the image density level for black pixels on test
pattern printouts (patterns are made with SP2-902)
This SP affects all test patterns except for the
grayscale test patterns.
[0 ~ 15 / 15 / 1/step]
Polygon Motor Idling Time 915*
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.
[0 = None / 1 = 15 s / 2 = 25 s]
Toner Supply Mode 921*
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.
[ 0 = Sensor 1 / 1 = Sensor 2 / 2 = Fixed 1 / 3 = Fixed
2]
Toner Supply Time 922*
Adjusts the toner supply motor on time for sensor
supply mode.
This SP is effective only when SP2-921 is “0” or “1”.
Increasing this value increases the toner supply motor
on time. So, use a high value if the user tends to make
lots of copies that have a high proportion of black.
[0.1 ~ 5.0 / 0.6 / 0.1 s/step]
Toner Recovery Time 923*
Adjusts the toner supply motor on time during recovery
from toner near-end/end.
This SP is effective only when SP2-921 is “0”, “1”, or
“2”.
Note that toner recovery is done in a 3-second cycle.
So, the input value should be a multiple of 3 (e.g. 3, 6
,9). See “Toner Density Control” for more details.
