Function/[Setting]
Checks the fusing nip band
[1 = Start / 0 = Stop]
Displays the fusing lamp power control frequency
which is detected by the zero cross signal generator.
Under "54" equals 50 Hz. Otherwise, 60 Hz.
Adjusts the paper feed amount allowed by the clutch
(see the table below) after correcting the skew at
registration.

Paper Feed Station
By-pass Feed
1st Paper Tray
Other Paper Trays
When paper jams occur after restarting paper feed
after registration, increase the value to help the
registration roller feed the paper.
[0 ~ 10 / 0 / 1 mm/step]
Determines whether or not to detect if the built-in copy
tray is full.
[0 = No / 1 = Yes]
Adjusts the time that the paper overflow sensor must
remain on before a message appears on the LCD. The
sensor may be switched on and off again if the paper
is curled, giving a false tray full detection. This SP
prevents this problem.
This SP mode is used when SP1-905 is set to 1.
[100 ~ 5000 / 500 / 10 ms/step]
If a middle size threshold is not stored with SP1-908-9,
this SP adjusts the upper paper lift motor reverse time
for paper sizes larger than the small size threshold set
with SP1-908-8.
If a middle size threshold is stored with SP1-908-9,
then this SP adjusts the motor reverse time for sizes
larger than the middle size.
Do not input a value greater than 1,200.
Use this SP when a paper feed problem occurs from
the 1st paper tray.
See "Paper Lift Mechanism" for details on SP1-908.
