Specifications

2. Connect the Data Ribbon Cable from J2 on the Cutter Board to J5 on the
Main Logic Board.
3. Attach the AC Power Cord and turn the printer ON. (If the Cutter Motor
starts, wait for it to stop.)
NOTE: A critical position adjustment is made in steps 4 and 5. The Cutter Motor
must be rotated until the two flat surfaces on the Cutter Motor shaft are
aligned with the set screws in the Lower Drive Arm, while the Lower Drive
Arm is in a vertical position (Sensor Flag down).
4. Refer to Figure 5.23. Attach a test clip at one end of a jumper cable to the
lead on the left end of Capacitor C6 (+5 VDC SOURCE) on the Cutter
Board.
5. Briefly touch the test clip at the other end of the jumper cable to Test Point
TP1 on the Cutter Board to “jog” the Cutter Motor to the desired position.
6. Position the Lower Drive Arm so the Sensor Flag is centered between the
front and back portions of the Cutter Optical Sensor, then tighten the two
set screws.
7. The set screws must be extremely tight to insure proper operation of the
Cutter Mechanism. Tighten the set screws with a 5/64" Allen Key. (As a
reference, when the set screws are tight, the Allen Key should deflect
approximately 0.6" (1.5 cm) past the point of tightness. The tightness
specification is 20 in. lbs. (2.3 N-m).
8. Activate the Cutter Motor, and make certain the Sensor Flag travels through
the slot in the Cutter Optical Sensor without touching it.
9. Turn the printer Power Switch OFF.
Upper Drive Arm Alignment
The Upper Drive Arm is part of the Cutter Mechanical Assembly and has been
properly aligned at the factory. If for some reason the factory position is altered,
the following procedure may be used to realign the Upper Drive Arm. The
printer must be programmed to operate in the Cutter Mode prior to performing
the following procedure.
1. Remove the printer’s Left Side Panel, if attached.
2. Loosen the Allen head cap screw that clamps the Upper Drive Arm to the
Rotary Cutter Blade shaft. (The Drive Arm may be snug on the shaft.)
3. Apply power to the printer. The Lower Drive Arm of the Drive Link
Assembly should rotate once and stop when the Sensor Flag activates the
Optical Sensor.
4. Refer to Figure 5.24. Only after the preceeding step, hold the Upper Drive
Arm in position and adjust the Rotary Cutter Blade so that the gap between
its cutting edge on the left end and the cutting edge of the Rear Cutter Blade
is approximately a .100" (2.5mm) as gauged by eye.
NOTE: If the gap between the cutting edges is too large, the cutter may not cut
properly across the entire media width. If the gap is too small, the media may
catch on the Rotary Cutter Blade edge and cause a jam.
5. Position the Upper Drive Arm out from the cutter frame so its flat surface is
flush with the end of the Rotary Cutter Blade shaft.
