4.5 Error Indications

 Paper end, paper near-end
The end of the roll of paper is detected at two stages, paper near-end and paper
end.
When paper near-end is detected, the PAPER LED flashes. Prepare a new paper
roll.
When paper end is detected, the PAPER LED lights and the buzzer sounds. Load a
new paper roll. Memory switch settings can be used to disable the buzzer.
 Cover Open
If the cover is opened, the COVER LED lights.
The buzzer may also sound depending on the memory switch setting.
Do not open the cover during printing. If the cover is accidentally opened, the
COVER LED flashes. Check the paper, pull it straight out of the printer by a couple
of centimeters, and then close the cover. Printing restarts. A command must be sent
to restart printing depending on the memory switch setting.
 Cutter error
If the auto cutter cannot move because of a paper jam or something else, the
CUTTER LED flashes and the buzzer sounds. Remove the cause of the trouble and
press the FEED button. If the auto cutter still does not move and the paper cover
cannot be opened, refer to "Clearing a Cutter Error."
 Print head hot
When you print dense characters, dark images, or for an extended time in a hot
environment, the print head temperature increases. If the print head exceeds a
specified temperature, the printer stops printing and waits for the print head to
cool. When this happens, the PAPER LED, CUTTER LED, and COVER LED flash.
Printing resumes automatically when the print head cools.
