Appendix R PRINTER UNIT HANDLING
R.1 When purchasing this product

To prevent static electricity damage to thermal head elements and IC sensors, take steps to prevent static
electricity and ensure that your body is grounded before handling the product.

To prevent malfunction and static electricity damage to thermal head elements and IC sensors, ensure that the
frame (casing) is properly grounded before installing the product.
R.2 Notes on use

This printer uses a line thermal head. For longer head life, avoid using in areas that are noticeably dirty and
dusty.

Since a thermal head is used with this printer, do not expose it to condensation.
If condensation is on the product, do not turn on the power until the condensation is gone.
R.3 Prohibitions

Do not touch thermal head elements, driver ICs, and connectors directly with your fingers, a screwdriver,
tweezers, etc.

Protect the thermal head surface from mechanical stress and impacts (including friction from particles).

During operation and right after the end of operation, do not directly touch areas near the thermal head and
motor.

Keep contaminants from adhering to the thermal paper and platen.

Do not apply excessive force to the connectors.
R.4 When not using for a long period

If roll paper is left set for a long period, it may discolor or fade, and may stick to the platen. Also, deformation
of the platen rubber may cause some printing to lighten.
R.5 When using at low temperature

When printing starts (particularly at low temperature), the initial printing may be somewhat light due to the
head being cold.
R.6 When using at high temperature

When printing at high temperature, print bleeding or other print quality problems may occur.
