1 ESC G command
2 Data block (image data for one block)
3 ACK code (acceptance of the data block)
4 CAN code (abort scanning)
5 ACK code
Sending the CAN code does not reset the parameter settings in the
scanner, unless the ESC @ (initialize the scanner) command is sent,
or the scanner is turned off and back on. Settings made with the
control panel remain in effect unless corresponding commands are
sent to override them.
To restart scanning, send the ESC G command again. It is not
possible to resume scanning from where it was aborted. The standard
procedures of scanner control should be repeated from the beginning;
do not send only the ESC G command to restart.
Note:
When scanning is terminated by the CAN code, the carriage returns
to the home position. To start another scanning operation, wait until
the scanner is ready. The BUSY line on the bi-directional parallel
interface, or the DTR line on the serial interface, indicates when the
scanner is ready, and the READY light on the scanner’s control
panel comes on.
