VENTILATION INLET CLEANING
Maintain the ventilation inlets (rear and left side) clean. You may use a vacuum to clean
as illustrated in the diagram.
THERMAL HEAD CLEANING
When lines appear on the printed images, clean the thermal head.
Preparations
Alcohol (ethyl alcohol, etc.)
Soft and clean cloth
Press the latch bar, pull out the printing unit forward, and
release the bar to open the door.
Remove the paper strip bin.
Remove the ink ribbon out of the printer.
Wipe the head cleaning part (as shown right) carefully with
cloth dampened with a small amount of alcohol.
• Do not damage the thermal head.
• When the poor print quality is not corrected even if the head has been
cleaned, replacement of the thermal head may be required. Contact your
dealer.
NOTE
Thermal head and the motor will be hot right after printing. Wait until they have
cooled down before cleaning the thermal head.
CAUTION
The thermal head may be damaged if you touch it while static electricity builds
up on your body.
NOTE
• When you clean the thermal head, make sure not to apply excessive force
to the peeling roller on the bottom of the thermal head. When the excessive
force is applied to the roller, the roller may be deformed, resulting in
deterioration of the printing quality.
