Effect obtained by adjusting the upper limit position
  1. Moving the upper limit position downwards (When there is a double feed or non feed caused by a double feed)
    The paper is separated when feeding the paper.
  2. Moving the upper limit position upwards (When a non-feed occurs)
    The resistance to paper feed can be decreased.
Adjustment Procedure

  • The tray weighs 25 kg empty. To prevent damage to the tray and personal injury, never attempt to lift the tray alone. The tray must be lifted by two or more persons.

  1. Pull the tray [A] out of the LCT until it stops.
  2. Remove the screws from the right rail [B].
  3. Remove the screws from the left rail [C].

  4. Lift and remove the tray [A].

    • You do not need to remove the screw for the stopper pin bracket at the back of the left rail.

  5. Open the front door [A], and then remove the inner cover [B].
  6. Pull out the paper feed unit [A], and then remove the screw [B].
  7. Remove the paper feed unit [A].
  8. Remove the TCRU/ORU screw and adjust the upper limit sensor bracket [A].
Installing the Upper Limit Sensor Bracket
  • When a double feed or non-feed caused by a double feed occurs.
    A scale is marked on the stay [A]. 1 division [B] is 1.0 mm.
    Install the upper limit sensor bracket [D] to increase the clearance [C] between the stay and the upper limit sensor bracket.
    If the upper limit sensor bracket is moved 0.5 mm away from the position where the upper limit sensor was installed, the upper limit position moves 0.8 mm downwards.


  • When a non-feed occurs
    A scale is marked on the stay [A]. 1 division [B] is 1.0 mm.
    Install the upper limit sensor bracket [D] to decrease the clearance [C] between the stay and the upper limit sensor bracket.
    If the upper limit sensor bracket is moved 0.5 mm closer to the position where the upper limit sensor was installed, the upper limit position moves 0.8 mm upwards.
After the Adjustment

After adjusting the upper limit sensor bracket, a paper feed error can occur depending on the type of paper.

  • When the upper limit sensor has been moved downwards: A non-feed can occur.
  • When the upper limit sensor has been move upwards: A double feed can occur.

If a paper feed error occurs, install the upper limit sensor bracket [B] so that the bracket is positioned as shown below, with relation to the long graduation mark in the center of the scale, and the blue mark [A].
