Adjustments and 
Maintenance 
 
This section details important adjustments, settings and periodic 
maintenance requirements that will ensure optimum performance.  
 
 
4.0    Media Sensor Adjustment 
 
The Media Sensor in the printer has two functions:  
 
(1)  To sense the presence of ticket stock; and,   
 
(2)  To detect the Top of Form (TOF) Mark (a black stripe, rectangle, or 
square, as shown in the illustration below).  
 
The Media Sensor must be adjusted 
so that it can “see” the TOF Marks on 
the ticket.    
 
When adjusting the sensor make sure 
that it is positioned within a Quiet 
Zone (and not over preprinted text or 
graphics, since that can cause false 
TOF sensing).  
 
Section 6 details other specific 
requirements for ticket stocks. 
 
Always align the
Media Sensor
over a Quiet Zone
Preprinting

TOF Mark
(Black Stripe)
 
 Note:   If the ticket stock you are using does not contain TOF Marks, ‘TOF 
Sense’ must be set to ‘Continuous.’ (When using this setting, the 
length of the ticket is set via software commands.) See Section 4.3. 
In this case, the Media Sensor can be adjusted to any location over 
the ticket stock. 
 
Depending upon the printer model and options, the adjustment of the 
Media Sensor differs slightly, as detailed in the following subsections.
