Epson SQ-2000, Operating Manual

Paper-end detector
The printer is equipped with a
paper-end detector
that warns
you when the printer runs out of paper.
When
the printer detects
that the paper has run out, printing stops, the PAPER OUT in-
dicator goes on and the buzzer sounds.
The PAPER OUT light goes out when paper is loaded. Howev-
er, printing does not restart until the ON LINE switch is pressed.
The SQ-2000 has an override which allows the paper to move
approximately one inch after the end of paper has been sensed.
For this reason, always remove paper using the LF or FF buttons.
If you manually remove the paper from the printer, you won’t
be sure the paper end has been detected. It is possible to later
place the printer in the on-line state and have data lost (and
printed onto the platen) if you don’t follow the correct procedure.
Ink low
When the ink cartridge is nearly empty, the INK LOW indica-
tor lights and the buzzer sounds. Only 66 additional lines (ap-
proximately one page) can be printed in this state. If the ink is
low when the printer is switched on, the INK LOW indicator
lights up and the printer remains off-line until the ink cartridge is
replaced. To restart the printer, replace the cartridge, perform the
head cleaning operation (explained in Chapter 4), and then set
the printer on-line.
Buzzer
The buzzer
is located on the control circuit board. It sounds for
about 0.25 second in the following cases:
l
When the BEL code (ASCII code <BEL>) is sent to the printer.
l
When the end of the paper is detected.
l
When the printer carriage malfunctions.
l
When the printer is out of ink.
Note:
The buzzer can be switched off when DIP switch SW2-6 is set to
ON (up). If a malfunction occurs the buzzer will sound even if
the switch is set to ON.
