MAINTENANCE
Periodic Maintenance
Perform the following maintenance periodically.
The printer power should be turned off when performing maintenance.
Period: Every six months, or every 1 million printed lines
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 (paper dust) that may be adhering to
it.
Detectors and the Surrounding Areas:
• Remove any dirt, dust or paper cuttings that may be adhering to the detectors (mainly the reflective type
photosensor).
Note 1: Immediately after printing, the thermal head is extremely hot. Do not clean the thermal head.
Note 2: When cleaning the thermal head, there is the potential of damaging the head through exposure to static
electricity. Be especially careful when performing maintenance in this area.
Note 3: After cleaning the thermal head, allow the alcohol to completely dry before turning on the power.
Handling Recording Paper Jams
If recording paper should become jammed, open the platen unit and remove the jammed paper.
Never pull on the jammed paper unnecessarily while the printer unit is closed because this can damage the drive system
parts.
If the auto-cutter becomes locked because of jammed paper in the printer, absolutely never forcefully open the printer cover.
This can damage the cutter unit. If the cutter locks, release the lock as described before opening the printer cover.
Remove jammed paper according to the following procedures.
Releasing the Cutter Lock
Use the following procedures to release the auto-cutter lock if trouble occurs, such as when paper becomes jammed.
1. Turn the printer power off.
2. Remove the front cover.
3. Rotate the emergency knob in the direction of the arrows on seals on the top of the auto-cutter unit housing
and marks on the housing case to return the cutter blades to their home positions.
The emergency knob should be rotated using a tweezers, screwdriver or ball-point pen to prevent accidents.
4. Return the front cover to its original position.
