1-3 Precaution for Electrostatically Sensitive Devices (ESDs)
1. Some semiconductor (solid state) devices are easily damaged by static electricity. Such components are
called Electrostatically Sensitive Devices (ESDs); examples include integrated circuits and some field-effect
transistors. The following techniques will reduce the occurrence of component damaged caused by static
electricity.
2. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge
from your body by touching a known earth ground. Alternatively, wear a discharging wrist-strap device.
(Be sure to remove it prior to applying power-this is an Electric shock precaution.)
3. After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to
prevent accumulation of electrostatic charge.
4. Do not use freon-propelled chemical. These can generate electrical charges that damage ESDs.
5. Use only a grounded-tip soldering iron when soldering or unsoldering ESDs.
6. Use only an anti-static solder removal device. Many solder removal devices are not rated as anti-static;
these can accumulate sufficient electrical charge to damage ESDs.
7. Do not remove a replacement ESD from its protective package until you are ready to install it.
Most replacement ESDs are packaged with leads that are electrically shorted together by conductive foam,
aluminum foil or other conductive materials.
8. Immediately before removing the protective material from the leads of a replacement ESD, touch the
protective material to the device will be installed.
9. Minimize body motions when handling unpacked replacement ESDs. Motions such as brushing clothes
together, or lifting a foot from a carpeted floor can generate enough static electricity to damaged an ESD.
1-4 Operational Precautions
1. The heating element of the printer mechanism’s thermal head and the driver IC are easily damaged.
Never allow these components to come into contact with metal or other hard objects.
2. Never touch the printer mechanism’s heating element with your hand. Doing so can damage the heating
element and affect proper operation.
3. The head and motor areas are very hot during and immediately after printing. Do not touch components
in these areas directly with your hand.
4. Do not use any paper other than these specified in this manual otherwise print head reliability and print
quality are affected adversely.
5. Thermal paper starts to color at around 70ºC. Take care to protect unused and printed thermal paper
against the affects of heat, light and characters on the paper to feed.
6. Take the roll paper out of the printer when you will not use the printer for a long time in a high
temperature and humidity environment.
