For maintenance operations, note the following:
Notes:
(1) Do not disassemble/reassemble or adjust the machine, if it functions properly. Particularly,
do not loosen screws on any component, unless necessary.
(2) After completing an inspection and before turning on the power, be sure to check that there is
no abnormality.
(3) Never try to print without paper installed in the printer.
(4) Check that the printing paper and platen roller are properly set.
(5) During maintenance, be careful not to leave parts or screws unattached or loose inside the
printer.
(6) When handling the thermal head, do not use gloves or other aids which can easily cause
static electricity.
(7) When disassembling or reassembling, check cables and boards for any damage. Do not run
cables into a narrow space or set cables in improper positions.
