2.2.7- PAPER-NEAR-END AND TICKET PICK-UP CONNECTORS .
Moreover than the no-paper sensor provided by the CAP9000 mechanism, the
TK51/IF9000 includes two connectors to control the outside paper status. In both of
them must be connected reflective optical sensors (see next table).
Through the paper-near-end sensor (CON8) user can control how much paper remain,
and therefore, to order a new paper reload before to fully exhaust the paper roll.
The ticket pick-up sensor (CON9) informs to the system if the last ticket printed has
been picked-up, so that it can take the suitable action. The status of these sensors can
be tested by the
DEL EOT command. Next picture shows an example built in the TK51
printer (see in APPENDIX-F).
