c- Error LED
Indicate all error status. Under normal conditions, ERROR LED is always off. under error
conditions, ERROR LED will flash.
d- Micro-switch
Detect the status of top cover.
e- Paper near end sensor
When the paper near the end, the error LED will flash. the printer will continue printing until the
paper end.
f- Paper end sensor
Paper end sensor is used to detect whether the paper roll has run out.
g- Power switch
Turn on/off the printer. “O” is to turn off the printer; “—” is to turn on the printer.
h- Paper guide
There are 4 long slots at the bottom of the paper cabinet. Putting the paper guide in a different
slot will allow the printer to use different paper widths listed as follows: 80±0.5 mm, 76±0.5
mm, 69.5±0.5 mm, 57.5±0.5 mm . Removing the paper guide will allow a paper width of
82.5 ±0.5mm.
Caution:
The Paper guide is an indispensable part of the printer and should be kept in the printer.
3.2 Error LED and Buzzer
The error LED and buzzer indicate the states of the printer, as described in the table below:
Errors Voice of buzzer LED flash
Cutter error (paper jam) Long-short-long Fast
Print head is raised up Short-long-short Slow
Print head is overheated (＊)
Long-short-long Fast
Paper near end No Faster
Paper end Short-short-short Faster
＊ The printer can detect the temperature of the print head with thermal resistor. If the
temperature of the print head has increased too much, the printer will decrease its print speed. If
the temperature becomes higher than 65
0
C, the protection circuit of the printer will force the
printer to stop printing; at the same time the light and sound signals as described in the table will
be given.
