PAPER LIFT MECHANISM
For A4-SEF paper or wider, a projection [H] on the side fence engages the
secondary pressure spring [J] through a lever [I]. Then, the secondary pressure
spring [J] applies paper feed pressure in addition to the main pressure spring [K], to
ensure that extra pressure is applied to wider paper.
When the paper tray is pulled out, the pins [A, C] disengage from the couplings [B,
D], and the bottom plate drops. To make it easier to push the tray in, the lift motor
rotates backwards 1.7 seconds to return the bottom plate pressure lever coupling
[D] to the original position.
The lift motor on timing can be adjusted with SP mode, to change the pressure
from the main pressure spring.
• SP1-908-1 (1st tray), 1-908-2 (2nd tray)
• Default: 0
• Increase the pressure: +1, +2
• Decrease the pressure: –1, –2
If the pressure is too strong, the sheet of paper may not be fed smoothly, and if it is
too weak, more than one sheet of paper may be fed at a time.
The pressure depends on the paper size.
