3.8 Paper Sensors

The printer has 2 paper sensors as follows:

1) Paper roll end sensor

The sensor which detects whether paper is present or not. When the sensor detects a paper-end, the printer stops printing.

2) Paper roll near-end sensor

The sensor which detects a near-end of a paper roll.

When the paper roll diameter becomes sufficiently small, the detects a near-end of the paper roll and the PAPER OUT LED lights. If the sensor is enabled by ESC c 4, the printer stops printing.

NOTE: After installing new paper roll, close the printer cover; then the printer restarts printing.

3.9 Cover Open Button

When the cover open button (located to the right of the cover) is pressed, the printer cover is opened. When the cover is closed, the cover open button is latched.

NOTES: 1. Be sure to use the cover open button to open the printer cover.

2.Do not open the cover during printing.

3.Do not open the cover during auto-cutting operation; otherwise the mechanism may be damaged.

3.10Cover Open Sensor

The cover open sensor monitors the printer cover. When the sensor detects a cover open during printing, the error LED blinks 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 paper roll end sensor.

3.11 Print Buffer-full Printing

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).
