    8. SETTING PAPER AND USING THE ACCESSORIES 8.1 Setting Paper (See Figure 8-1) 1) Cut the leading edge of paper to be set straight across the end. 2) Insert the paper straight along the paper mounted thermal mechanism and between the presenter paper guide and paper holder.

  • Page 21: Using The Accessories (Weight Shaft And Loop Guide)

    8.2 Using the Accessories (Weight Shaft and Loop Guide) Paper thickness: Min. 0.065 to Max. 0.10 mm. (See Figure 8-2) 1) No shaft is used so fasten the 3 hooks in the 3 positions on the rear guide so that they do not get lost. 2) Fasten the loop cutter to the cutter with the 2 accessory screws.
  • Page 22 3) Rotate the paper holder and set after checking that it does not interfere with the loop guide. Note: Floating therebetween the cutter can occur because of deformation in the loop guide caused by sudden environmental changes. (See fig. 8-3) If that should occur, follow the directions above for the mounting of the loop guide and remount it so that it does not float.
  • Page 23 Paper thickness: Min. 0.10 to Max. 0.15 mm. (See Figure 8-4) 1) Fasten the shaft with the left and right hooks positioned on the Paper Holder. 2) Check that the shaft is securely fastened to the Paper Holder hooks to set it. Note 1: The 2 positions of the Paper Holder should be adjusted for the thickness of the record- ing paper, the length thereof and the environment of use.

    9. RECOVERING FROM ERRORS (PAPER JAMS) Remove jammed paper according to the directions shown in Figure 9-1 and 9-2 to recover from non-recov- erable paper jams. When doing so, always verify that the power has been turned OFF. (Procedure 1) 1) Rotate the knob in the clockwise or counterclockwise direction.
  • Page 25 (Procedure 2: When Paper Cannot be Removed with Procedure 1) 1) Remove the screws on both sides of the presenter, shown in the figure below. 2) Rotate the rear guide and remove the jammed paper. 3) After removing the jammed paper, reverse the procedure 2), then fasten the screws in their original positions.

  • Page 26: Precautions Regarding Outer Cover Designs

    10. PRECAUTIONS REGARDING OUTER COVER DESIGNS To prevent jams at the presenter discharge outlet, consider designing the casing so that recording paper does not enter between the presenter unit and the case. 1 Gap of *1 must be a maximum of 1 mm. (See Figure 10-1) 2 The dimensions of *2 must be larger than the presenter discharge outlet (2 mm), but it should be small enough that it does not block the paper discharge outlet.(See Figure 10-1) If it is too large, interfering light (from the sun, etc.) will enter from outside of the apparatus from the recording...

    12. HANDLING THE PRESENTER 12.1 Precautions in Handling 1) Do not store or use the printer in locations that are dusty, oily or exposed to metallic dust. 2) Do not apply an unreasonable amount of force on the body. (This can disfigure the frame and lead to the printer not functioning properly.) 3) Avoid sudden changes even if the ambient temperature and humidity are within standard conditions.
