5. Close the cover by rotating it back into position until it securely clicks into
place. Paper will feed automatically, and then print and eject a test ticket.
Cleaning the Print Head
Once the unit is opened, the paper path is accessible for cleaning or clearing
paper. Use a soft brush to clean the paper dust from inside the printer. The
paper dust should also be removed from the sensor optics. If streaking on the
printed ticket is evident, the thermal print head may need to be cleaned. This
can be with a cotton swab moistened with an alcohol solvent (ethanol,
methanol, IPA).
Warning: After printing, the print head can be very hot.
Be careful not to touch it and let it cool down before you
clean it. Do not damage the print head by touching it
with your fingers or any hard object.
Clearing Paper Jams
If paper becomes stuck in the printer’s knife mechanism, it is important to note
the following when clearing jammed paper from the knife area:
1) Turn the printer power off.
2) Open the printer’s top cover.
3) Tear as much paper away from the knife by hand, pulling the paper toward
the center of the paper path.
4) Using a plastic or wooden thin tool (do not use metal tools), gently push
any trapped paper on either the left or right sides toward the knife’s center.
Be aware that the knife’s blades cannot be pried apart; any attempt to do
so will permanently damage them.
5) After removing all of the visible paper from the knife, turn the printer’s
power back on. The knife will eventually cycle and return to its home
position.
