OPERATING PRECAUTIONS
Follow the precautions below to deliver and maintain the full performance of the printer.
■ Using the Printer
♦ Be careful not to drop or bump the printer on a hard surface.
♦ DO NOT install the printer in direct sunlight or such areas.
Be careful about the ambient temperature and humidity.
Suitable environment for the use of the printer is as follows:
• Range of the temperature: 5 to 45°C
• Range of the humidity: 10 to 90%RH
Refer to the technical reference for the allowable humidity range at each temperature.
♦ DO NOT install the printer near devices that generate strong electromagnetic fields such as a copy
machine.
♦ DO NOT install the printer in a location that is subject corrosive gas or siloxane and so on.
♦ DO NOT connect the AC cable or the AC adapter to the same outlet with devices that generate
noise.
♦ DO NOT open the paper cover during printing or cutting.
♦ DO NOT connect or disconnect the interface cable during printing or transmission. DO NOT touch
the connectors of the interface cable during printing.
♦ Turn the power off when not in use.
In addition, if the printer is not used for a long time, unplug the AC plug from the outlet, and set
thermal paper to protect the platen roller.
♦ Clean the printer case using soft, lint-free cloth. DO NOT use alcohol or other solvent.
♦ Before using, always clean the terminals using a dry, soft, lint-free cloth. If the terminals are dirty, it
may not be possible to obtain proper contact.
♦ DO NOT touch the thermal head directly. Doing so may result in poor quality due to the dirt or
damage by the static electricity.
♦ DO NOT use the thermal head with getting wet. Doing so may cause the printer damaged.
♦ When cleaning the thermal head, wipe the thermal head with a cotton swab or other soft material.
♦ The AC adapter may become warm when in use. This is normal and is not a malfunction.
♦ High-print-rate printing or using the printer under low temperature condition might cause irregular
printouts or generate loud sound. This is not a failure in the printer, but an inherent paper
phenomenon.
♦ When handling the printer, be aware of static electricity. If the static electricity is discharged, this
could cause a USB communication failure. When this problem occurs, disconnect the USB
connector that is connected to the host device and wait a few seconds before connecting it again.
♦ DO NOT print without the thermal paper.
♦ DO NOT drop or insert any foreign objects such as a clip, a pin, or a screw in the internal parts or
slot of the printer.
♦ DO NOT drop any liquid or spray a solvent to the printer.
♦ NEVER push the switch on the operation panel using sharp object such as pen tip.
