Cleaning as indicated below will help maintain stable printer operation and extend the printer's life.
Wearing gloves at cleaning is recommended to prevent injury.
Make sure to turn off the power before cleaning.

THERMAL HEAD CLEANING

Take the ink cassette out of the printer.
Preparations
Alcohol (isopropyl alcohol)

Other : Cleaner pen (option)*
* Please ask the dealer about options.
When lines appear on the printed images, clean the thermal head.
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.
Thermal head is hot right after printing. Wait until the head cools before
cleaning the thermal head.
The thermal head may be damaged if you touch it while static electricity builds
up on your body.
Do not use 10x15 (4x6") or 15x20 (6x8") size paper (having width of 152 mm) after
using 9x13 (3x5") or 13x18 (5x7") size paper (having width of 127 mm) for a long
time or printing such paper in large quantities.
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 parts supporting the roller may
be removed. In addition, the part of the cloth used for cleaning may remain between
the roller and the supporting parts, resulting in deterioration in the printing quality.
