Adjusting and
Maintaining the Printer
This section details important adjustments, settings and periodic
maintenance requirements that will ensure optimum printer performance.
4.0 TOF Sensor Adjustment
The TOF Sensor in the printer has two functions: (1) sensing the
presence of ticket stock and (2) when using reflective stock, sensing the
Top of Form (TOF) Mark on each ticket. If the ticket stock does not
contain TOF Marks, DPL programming must be used to set the ticket
size.
To advance tickets correctly,
the sensor must be positioned
under the TOF Mark and
within in a Quiet Zone (an area
free of preprinted text or
logos); see Section 6 for stock
requirements.
þ Note: Preprinted text and logos can cause false TOF readings.
Depending upon the printer model, the adjustment of the TOF Sensor
differs slightly.
