9.1.1 Cut or Tear Opto
There is one optical sensor (opto) mounted on an adjustable aluminum bracket. The opto controls
the cut or tear position. Removal or adjustment of the opto should be done without removing the
bracket from the paper guide. The opto position is factory set and adjustment should not be
necessary.

Note: Before making any opto adjustments make sure your ticket stock was manufactured to proper
ticket specifications.
To adjust the cut or tear position, physically adjust the opto mounting bracket forward or backwards
to achieve the desired cut or tear location. 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 edge of the cabinet or top plate.
Minor adjustments (no greater than 3/16”) to the cut or tear position may also be done via the control
panel (if applicable) by changing the INC/DEC CUT1/2 settings. (See Appendix A). For a 200dpi
printer the INC value should not exceed 38. For a 300dpi printer the INC value should not exceed
55. Going beyond these values will cause reliability issues.
If you are not able to get the desired cut position, make sure your ticket stock was manufactured to
proper specifications.
Once a year the opto eye should be blown off with air. This interval will vary depending upon the
environment and the quality of the ticket stock.
