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
  1. Open the top right cover [A].
  2. Remove the top left cover [A].
  3. 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.
    When the upper limit sensor bracket [C] is moved 0.5 mm in the direction of the red arrow 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.
    When the upper limit sensor bracket [D] is moved 0.5 mm in the direction of the red arrow from 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: Non-feed can occur.
  • When the upper limit sensor has been move upwards: Double feed can occur.

If a paper feed error occurs, install the upper limit sensor bracket [B] so that the top of the bracket is flush with the long graduation mark [A] as shown below.
