Time-Out When Charging
The printer believes that too much time was required to bring the battery up to a normal
charge voltage. A maximum of 150 minutes is allowed for the charging cycle. This is an
indication that the battery should be replaced.
Low Thermal Head Temperature
The temperature of the thermal head is too low for reliable printing (less than 0°C (32°F)).
You need to use the printer in a warmer environment.
If this condition occurs in relatively warm environment (for example, at room temperature),
the printer should be returned for service.
High Thermal Head Temperature
The temperature of the thermal head is too high. If allowed to become even hotter, the
thermal head would begin imaging the paper in areas not intended to be printed. The printer
will stop while the head cools down and then will resume printing. This condition is normal
when printing documents with a great deal of “black” content.
To avoid or delay the onset of this condition, you can print using a lighter density setting,
reduce the amount of “black space” being printed by removing background shading and
colors (for example, background on Excel graphs or PowerPoint documents) and make sure
that the printer is not enclosed and has adequate ventilation.
Note: This condition may be worse at high altitude (>10,000 feet) due to a lower air density
available to cool the printer.
Data Receive Error
Data is being received but errors are causing the printer to request that it be re-transmitted.
This will slow printing speed and is almost always associated with the quality of an IrDA
connection. Try repositioning the printer or host IrDA until the errors cease.
