There is one opto device mounted on an aluminum or black plastic bracket beneath the paper guide. On a Lemur with auto cut the cut position should be a 1/16”-1/8” away from the ticket perforation. On a Lemur without auto cut the ticket perforation should line up with the top edge of the cabinet when you tear upwards.
The following steps should be done.
- The opto assembly may be moved forward or backwards to achieve the desired cut or tear location.
- Sliding the opto forward (in the ticket feed direction) will increase the ticket travel before it is cut or torn. Sliding the opto backwards will decrease the ticket travel before it is cut or torn.
- Slide the opto assembly a little bit in the desired direction. Press the TEST button on the printer to print out some self-test tickets.
- If the cut or tear position is not in the desired location then repeat steps 2-3.
CAUTION: Care needs to be taken not to adjust the sensor too far back as it will bend the sensor away from the ticket thus causing it not to detect the black timing mark properly.
