This chapter lists a number of precautions that you should observe while using
the printer. It also provides information on cleaning the receipt printer
mechanism.
Operating Precautions
• The service life of the receipt printer’s thermal print head cannot be
guaranteed if any paper other than the recommended paper is used. There
will be a noticeable decline in the service life of the thermal element of
print head whenever you use paper that contains Na+, K++, or CI-.
• Never print when there is water or any other moisture (such as
condensation) on the surface of the receipt printer’s print head.

• The thermal print head of the receipt printer and the printer’s motor
become very hot during operation. Never touch these components while
the printer is in operation or immediately following a print operation.
• Never touch any moving parts of the printer, such as gears or knobs.
• To avoid personal injury, always exercise caution when moving your
hands near the edges of printer components, especially metal
components.
