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.

1. Position the loop guide and cutter in positioners 1 and 2.

2. Tighten the screw next to the positioner 1.

3. While pulling the next loop guide in the direction of the arrow, tighten the screw next to the positioner 2 so that it does not flow therebetween the cutter (see Fig. 8-3)

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.

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.

Note 2: The loop guide is not used, so store it so that it will not get lost.

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-recoverable 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.

2) Remove the jammed sheet from where it is easiest to remove. (Paper inlet, discharge outlet, of the lower recovery space)

(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.

Note: When fastening the screws in procedure 3), be careful not to pinch the wires shown in

the figure below.

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 paper outlet causing the paper detectors (sensors) to mis-operate, so do not make them too large.

1) The casing for the recording paper discharge outlet should have an outlet portion established such as *3 so that coins and clips do not fall into the casing. (See Figure 10-1)

2) Storage space for the recovery of recording paper should consider the length of the recording paper and degree of curling to all plenty of space. It is recommended to ensure approximately 100 mm or more space for storage depth. (See Figure 10-2)

11. MAINTENANCE

Perform the following maintenance periodically.

Maintenance Periods: Every six months or after a million lines of printing. Location of Maintenance: Each detector and the vicinity Content of Maintenance: Clean away and paper dust or dirt and dust adhering to the detectors in the

presenter.

Note 1: Always verify that the power supply has been turned OFF when performing maintenance on

the presenter.

Note 2: Remove the two screws on both sides of the presenter, as shown in Figure 11, and rotate the

rear guide upward to remove any dust and dirt on the paper detector in the presenter. After performing maintenance, return the rear guide to its original status and tighten the screws. When doing so, do not allow the screws to catch on the wires in the Figure 11.

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. Allow the printer to sit in its new environment for at least 30 minutes before use in the event there has been a sudden change.

4) Do not use the printer in an environment where condensation has formed. If condensation should form, absolutely never turn ON the power until the condensation has dried.

5) The setup angle for the presenter should be a maximum of ±5°, as shown in Figure 12.

6) Paper transport and life cannot be guaranteed when using recording paper other than what is recommended.

7) Be careful not to allow foreign matter to adhere to the recording paper.

8) Be careful not to apply an excess amount of force on the cable connectors.

9) When closing the presenter from an open state, verify that the presenter is securely locked before operating.

12.2 Precautions Relating to Safety

1) After operation is completed, the surface of the motor can be very hot, so be careful never to touch it directly with your bare hands.

2) When the presenter is operating, never touch the rotating members, such as the gears.

3) Handle the presenter engine (the metallic portions) carefully because they can cause serious injury.

4) To perform maintenance on the presenter, always verify that the power supply has been turned OFF.
