Precautions on Handling the Printer

Observing the following operational precautions protects the unit against damage.
CAUTION:
Do not turn off the printer while the autocutter is working. Doing so leaves the cutter
blade exposed, which prevents the roll paper cover from opening.
Do not pull out paper when the roll paper cover is closed.
Except for a paper jam, do not turn the autocutter knob when the cutter cover is
open. Turning it accidentally may expose the cutter blade, which prevents the roll
paper cover from opening.
The heating element of the printer mechanism's thermal head and the driver IC are
easily damaged. Never allow these components to come into contact with metal or
other hard objects.
Never touch the printer mechanism's (thermal head's) heating elements with your
hands. Doing so can contaminate the heating elements and affect proper
operation.
Do not open the roll paper cover during printing. The printer mechanism may fail.
