TS1700/TK18 PRINTERS OPERATION MANUAL
5.3. B
UTTON FUNCTIONS
Fig.5.4.
TS1700 button.
The on-board button has the following functions:
•
PAPER FEEDING: when the printer is powered on pressing the button will feed the paper.
The paper roller will not move under the following conditions:
- The paper roll end sensor detects a paper end.
- When the door is open.
- When another non-recoverable error is present.
•
SELF-TEST MODE
: If pressed on start-up with the door closed, it activates this mode.
•
HEXADECIMAL MODE:
In order to activate it, if the button is still pressed when the full Self-
test has been printed, the printer will prompt the user to hold the button to enter this mode. If
we do not hold the button in the next 3 seconds, the printer will exit to normal operation.
5.4. PA
PER SENSOR
The TS1700 has an integrated photo-sensor for ‘out of paper’ detection. 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. Final user can detect this errors by the
LED blinking pattern and the application developer can test them through the
DEL EOT
command,
being able to act accordingly. This error events can be also associated to the digital output in a way that
when it is triggered it is possible to switch an external device.
5.5.
OPEN-PLATEN SENSOR
The TS1700 has an integrated photo-sensor to detect the opening of the platen. The operation in
case this error is detected is basically the same as the preceding error.
NOTE: If TS1700 detects no paper or platen open while is printing it will stop the communication in
order not loose any data.
5.6.
OPTIONAL SENSORS
There is also option for three more sensors as described in section
- PHOTO-SENSORS
. These
are ‘near-end paper’ sensor, 'ticket picked-up' sensor and 'black mark' sensor.
•
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. Since no mechanical solution is provided for the
installation of this sensor depending how it is mounted it will detect a quantity of remaining
paper in the roll. Final user can detect these errors by the LED blinking pattern, and the
application developer can test them through the
DEL EOT
command, being able to act
accordingly. This event can be also associated to the digital output in a way that when it is
triggered it is possible to switch an external device.
