Confidential

3.9 Cover Open Sensor

The cover open sensor monitors the printer cover. When the sensor detects a cover open during printing, the error LED flashes and the printer stops printing. The printer recovers when the cover is closed. When the sensor detects a cover open while the printer is in the standby status, the printer goes offline. The printer recovers when the cover is closed.

NOTE: Whether the cover is open or not does not affect the status reported by the roll paper end sensor.

3.10Print Buffer-full Printing

•When printing in standard mode

When subsequent data is received after the printer processes one line of data in the print buffer, the printer automatically prints the processed line and feeds the paper by one line (in standard mode).

•When printing in page mode

When subsequent data is received after the printer processes one line of data in the print buffer, the printer automatically moves the printing position to the line after the processed one.
