TS2000 PRINTERS OPERATION MANUAL

. PA
PER SENSOR
The TS2000 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.

OPEN-PLATEN SENSOR
The TS2000 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.
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.
•
Ticket picked-up sensor is used to detect that a ticket has been printed but not picked up. In
order to do so is has to be installed in an appropriate paper nozzle or presenter. 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 as a beeper.
•
Black-mark sensor detects the black mark of a pre-cut paper roll so, if the printer is
configured correctly and the black-mark option is enabled the printer could cut the paper by
its pre-cut edge and print the ticket in the physical space that it is intended to.
5.6.1- Black mark sensor
The TS2000 has an optional specific sensor for optical (black) mark detection. (See
APPENDIX –
HOW TO ORDER
)
In order to be able of using this feature, the optical mark sensor must be enabled by programming
command (See command
DC3 ESC FS GS
).
The command that sets black mark offsets (
GS ( G
) require two parameters that must be
measured physically on the ticket: ticket length which is the distance between two consecutive cutting
lines, and distance from black mark to next cutting line. This parameters will be saved into non-volatile
memory.
This command takes into account the distance from the black mark sensor and the cutter blade
which is fixed in a particular assembly. For this reason, this distance must be kept if a different
implementation is taken.
