1903* Feed Clutch Re-energize
Adjusts the paper feed amount allowed by the clutch after correcting the skew at
registration. When paper jams occur after restarting paper feed after registration,
increase the value to help the registration roller feed the paper.
1903 1 By-pass Feed
1903 2 Tray 1 Feed
1903 3 Other Trays
1905* Tray Paper Full Detection
Determines whether or not to detect if the built-in copy tray is full.
1906* Tray Paper Full Timer
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 SP1905 is set to 1.
1908* 1st Bottom Plate Pressure Adjustment
1908 1 Normal Size
If a middle size threshold is not stored with SP1908-9, this SP adjusts the upper
paper lift motor reverse time for paper sizes larger than the small size threshold
set with SP1908-8.
If a middle size threshold is stored with SP1908-9, then this SP adjusts the motor
reverse time for sizes larger than the middle size.
Do not input a value greater than 1200.
Use this SP when a paper feed problem occurs from the 1st paper tray.
See "Paper Lift Mechanism" for details on SP1908.
[0 ~ 2000 / 200 / 1 ms/step]
1908 2 Small Size
Adjusts the upper paper lift motor reverse time for paper of the same size as or
smaller than the small size threshold set with SP1908-8.
Do not input a value greater than 1200.
Use this SP when a paper feed problem occurs from the 1st paper tray.
See "Paper Lift Mechanism" for details on SP1908.
[0 ~ 2000 / 600 / 1 ms/step]
1908 3 Middle Size
Adjusts the upper paper lift motor reverse time for paper sizes larger than the
small size threshold set with SP1908-8, up to and including the middle size
threshold set with SP1908-9. If a middle size threshold is not stored with SP1908-
9, this SP is not used.
Do not input a value greater than 1200.
Use this SP when a paper feed problem occurs from the 1st paper tray.
See "Paper Lift Mechanism" for details on SP1908.
