8.0 Maintenance and Adjustments
Your ticket printer is solidly constructed and has been designed for high volume use.
It requires minimal care to provide maximum service.
This section provides an overview of printer maintenance, including parts alignments,
adjustment and replacement.
For discussion purposes, the printer consists of two major modules or assemblies:
• Paper guide and print head assembly
• Logic board assembly
As a safety precaution, all service to the printer should be done with power off
and the AC cord unplugged from the printer.
8.1 Paper Guide and Print Head Assembly
The principal function of this assembly is to guide the ticket stock to the thermal print
head where thermal printing takes place. Additionally, this assembly houses the drive
platen and optical detectors. The total assembly can be removed from the unit if
necessary, however, all replacements and adjustments of the components of this
assembly can be done without removing the total assembly.
The most common adjustments and replacements regarding this assembly follows:
8.1.5 Optical Devices (see figure 8a & 8b)
There are two identical reflective opto devices mounted beneath the print head. The
opto on the top controls automatic selection on a Airline boarding pass or a bag tag.
There is one see-thru opto device located between the platen and ticket exit slot. This
opto controls the initial print position and the manual tear off position.
The opto position is factory set and adjustment should not be necessary.
Caution: Before making any opto adjustments make sure your ticket stock was
manufactured to proper specifications.
The ticket load opto should be positioned such that the printer automatically activates
the stepper motor at the proper time when tickets are loaded into the printer. When
loading tickets, the stepper motor should turn on when the ticket stops in front of the
thermal head. At this point, the ticket will be grabbed out of your hand and fed into the
printer. If the motor does not activate, make sure the ticket stock is loaded into the
printer properly. The printer should advance the ticket to the edge of the cabinate.
