1ESC G command

2Data block (image data for one block)

3ACK code (acceptance of the data block)

4CAN code (abort scanning)

5ACK 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.
