Determines whether or not to detect if the built-in copy
tray is full.

]
Tray Paper Full Timer
906*
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.

Normal Size
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.
