Pentax PocketJet 3 User Manual
No Battery Found When Charging
If this indication occurs immediately when attempting to charge the
battery, the printer did not “see” a battery when you tried to initiate
a battery charging cycle. Make sure the battery has been installed
and connected properly and that there are no broken wires at the
battery or connector. See page 31, “Installing the Battery.”
If the battery is connected properly, you may have attempted to charge the
battery and it has become overheated during the charge cycle. An internal
thermal breaker will open when overheated, and after cooling, will close
again. Allow the battery to cool before continuing to charge it. If the
problem occurs again, replace the battery.

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 -10°C). 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.

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 exacerbated by use at high altitude (>10,000
feet) due to a lower air density available to cool the printer.
