Cleaning the printer
Use a soft brush to clean paper dust from inside the
printer and chassis area. The paper dust should also
be removed from the sensor optics.
Cleaning the printer head
If streaking on the printed ticket is evident, the ther-
mal print head may need to be cleaned. This can be
done by inserting a thermal printer cleaning card.
1. Remove remaining tickets from the ticket path and
check for any debris.
2. Press the green label to relatch the platen/cover
assembly, if it has been opened.
3. Make sure that there is power to the printer.
4. Unpack a 2.5" x 6" Thermal Cleaning Card and in-
sert it into the feed path. The cleaning card will
automatically be drawn into the feed path.
5. Repeat the process if necessary.
6. Properly dispose of used cleaning card.
