Calibration
WARNING Class 2 laser light. Do not stare into the laser beam or a
reflected image of the laser beam.
WARNING Using controls, making adjustments, or performing
procedures other than those specified herein may result in
hazardous radiation exposure.
The validator should be calibrated when it is first installed or when
the printer displays Calibration warning. A special calibration bar
code card is included with the validator package.
1. Make sure the printer is on and the scanning beam is on. If the
beam is off, press the RESET button for less than 2 seconds to
turn on the beam.
2. Raise the media cover. Open the pivoting deck by rotating the
deck lock lever fully clockwise. The pivoting deck will swing
upward, exposing the bottom of the printhead assembly.
3. If the printer has the cutter option, put the cutter in the open
(down) position.
4. Remove the calibration bar code card from its protective sleeve
and slide it into the open printhead and under the scanning
beam. (Figure 16.)
5. Make sure the bar code is under the scanning beam and the
CALIBRATION light is on.
6. Press and hold the RESET button on the validator until the
CALIBRATION light begins flashing.
