8 MAINTENANCE
Perform the following maintenance periodically.
Maintenance Periods: Every six months or after a million lines of printing.
Thermal Head:
• Dampen a cotton swab with alcohol (ethanol, methanol, isopropyl alcohol) and use that to wipe away dirt on
the heating elements of the head.
Platen
• Use a soft, dry cloth to gently wipe the platen to remove any foreign matter that may be adhering to it.
(Rotate the platen to clean the entire surface.)
(Detectors and the Surrounding Areas)
• Remove any dirt, dust or paper cuttings that may be adhering to the detectors (mainly the reflective type
sensor).
Note 1: Immediately after printing, the thermal head is extremely hot. Do not clean the
thermal head then.
Note 2: When cleaning the thermal head, handle it carefully because there is the
danger of damaging it through static electrical discharges.
Note 3 Only turn on the power after the alcohol has completely dried.
