3.3- PAPER SENSORS
The TK14 has two specific photo sensors for paper: ‘out of paper’ and ‘near-end paper’.
The out of paper sensor has the basic function of informing the printer controller about the existence of
paper (on the printing line). Because there are some actions (as an example, printing without paper) that
could seriously damage the mechanism, this error blocks all the printer activities.
The ‘near-end paper’ sensor detects when the paper roll is near its end of file. This error, by default, does
not stop printing, but through the
ESC c 4
command, it can be achieved that the ‘near-end paper’
detection stops the printing. If a
25 mm
inner diameter paper roll is used, the sensor will trigger when
10 meters
of paper remain (approximately).
The final user can detect these errors by the LED, and the application developer can test them through the
DEL EOT
command, being able to act accordingly.
