It sounds for about 3 seconds when the Printer receives BEL code.
It sounds intermittently for about 30 seconds when the Printer falls into error status.
NOTE: Setting of the DIP switch pin 1-6 (on the control circuit board) OFF stops the buzzer from sounding under the above condi- tions.

FFSW: (Form Feed)

LF SW: (Line Feed)

When this switch is depressed once, the paper is advanced vertically to the next Top of Form position. This switch must be depressed while the Printer is OFF-LINE. Otherwise, the form feed operation will not be carried out.

The Top of Form position is initialized when the POWER switch is turned on or when INIT signal is applied to the interface con- nector. Therefore, before turning the POWER switch on to start operating the Printer, set the paper at the appropriate Top of Form position. (See “INSTALLATION” 7.1.4.)

The paper advances while this switch is being depressed. The line spacing for paper advancement is determined by ESC A+n code (described later). When the POWER switch is on, the line spacing is initialized at 1/6 inch.

The line feed operation is prohibited while the Printer is actively engaged in printing.

POWER: Illuminates while the Printer is receiving AC power.

READY: Illuminates when the Printer is ready to receive data.

PAPER OUT: Illuminates when the paper supply is near its end.

ON LINE: Illuminates when the Printer is in the ON-LINE mode.

2. Buzzer

The buzzer is located inside the Printer case, and sounds under the following conditions.

3. Paper End Detector

When the paper end detector (a reed switch located on the paper guide) detects that the paper is nearly exhausted, the signals on the interface connector change to the following statuses.
