4.0.1 ST Model Media Sensor Adjustment
The ST Model can be equipped with either a Standard or a Print Side
Media Sensor. Follow the appropriate procedure for the Media Sensor in
your printer:
Adjusting the Standard Media Sensor –
 Turn ‘Off’ the Power Switch. Open the Access Cover.
 Loosen the Thumbscrew and adjust the Media Guides to fit the width
of the ticket stock:
The guides should be positioned so that there is no side-to-side ticket
movement (too loose), but not so close as to cause friction or bowing
of the ticket (too tight). (See Step 5 in Section 3.2.1 for an
illustration).
Once properly positioned, tighten the Thumbscrew to secure the
Media Guides in place.
 Unlock the Printhead Latch and raise the Printhead Assembly.
 Grasp the Slide to move the Media Sensor. Position the sensor so
that it can see the Quiet Zone and the TOF Marks on the ticket stock,
as described in Section 4.0.
