Thermal Print Head
The print head should be cleaned periodically to prevent debris from building up on the print element. The
required cleaning interval varies greatly depending on the quality of the ticket stock and the amount of dust
entering the print area. Excessive dirt build up on the print head will result in reduced quality. Continuing to
run the print head in a dirty condition will reduce its life expectancy, as it is unable to diffuse its heat properly.
The thermal print head can be removed for cleaning or replacement, as follows:
1. Make sure power is off and the AC cord is disconnected from the printer.
2. DO NOT UNPLUG CABLE FROM PRINT HEAD.
3. Lift up on the cam lock assembly (located above the head mounting block or plate) to remove pressure
from the thermal head. Photo A
4. Lift up on the head mounting plate/thermal head to remove. Photo B
5. Clean the print head surface (the side that makes contact with the paper) with isopropyl alcohol. Photo C
6. Install the head by reversing the above procedures.
7. Restore pressure to the head by pushing down on the cam lock assembly.
8. The printer in now ready for operation.
9. If the print quality is still poor then the thermal head needs to be replaced.
10. To replace print head remove ribbon connector from print head and then remove print head from
mounting plate by removing two Philip head screws.
