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 powered on and in offline mode, and
that the validator power light and scanning beam are on. If the
beam is off, press the
RESET button for less than 2 seconds to
turn on the beam.
NOTE: In SL5/T5R Energy Star models, the Power Save mode
powers the validator off. Press the FEED key to restore
power and turn on the beam within 21 seconds.
2. If the printer has the cutter option, put the cutter in the open
(down) position.
3. Remove the calibration bar code card from its protective sleeve
and slide the top edge between the printhead and platen and
under the scanning beam. (Figure 23.)
NOTE: Do not unlock the deck lock lever.
