Registration Adjustment

  • Disconnect the stacker from the upstream unit and do this adjustment on the left side of the upstream unit connected to the main unit. To avoid damaging the cart set switch, be sure to remove the Roll-away cart from inside the stacker when you disconnect the upstream unit.
  • If a Booklet (or Stapler) finisher is connected downstream, paper cannot be output to the proof tray of the stacker. With a downstream finisher connected, do the adjustment after disconnecting the I/F cable of the finisher and then turning the main machine on.

  1. Load some A3 or 11”x17” paper in the 2nd tray of the main unit, and then output several sheets of single-side printing to the proof tray stacker.
  2. Watch the edge of each sheet as it exits the unit. If the edge is within the first notch (2 mm) on the scale, there is no problem. If the edge goes beyond the first notch, adjustment is required.
    [A]: This is the rear scale for 11"×17" (DLT)
    [B]: This is the front scale for A3
  3. Disconnect the stacker from the upstream unit.
  4. Remove bracket [A] of the upstream unit and rotate it to [B] (x1). Changing the position of this bracket aligns the oval cut-out horizontally and frees the joint bracket so that it can slide from side to side.
  5. Loosen the screws of the bracket and slide it to the left or right to adjust the position.
  6. Dock the stacker to the upstream unit again, print some more sheets, and then check registration and skew again to make sure that the edges of the sheet do not go beyond the first notch of the scale.
  7. If there is no problem, connect the units and set the shoes.

Manual Skew Correction

  1. Disconnect the stacker from the upstream unit.
  2. Remove the front right cover [A] (x3).
  3. Remove the skew adjustment spacers (x1).

  4. The adjustment bracket is [A] on the left side of the upstream unit [B]. Loosen the screws of the connection bracket, slide the bracket to the left or right to adjust the position, insert the spacer behind the bracket, and then tighten the screws.

    • A spacer is 2 mm thick. If the adjustment requires more than 2 mm, use another spacer.

  5. Dock the stacker to the upstream unit, and then do some more test prints, and if the amount of skew is still beyond the first notch, do the procedure again and insert another spacer if required.
  6. If no further adjustment is required, re-attach the right front cover of the stacker, and then connect the stacker to the upstream unit.
