Cleaning the Print Head
TO BE PERFORMED BY RLT ONLY USING ESD PRECAUTIONS
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.
If streaking on the printed ticket is evident, the thermal print head may need to be
cleaned (Figure 9-1). This can be with a cotton swab moistened with 91%
isopropyl alcohol.
