2.3 Buzzer
-
The buzzer is located inside the printer case, and sounds for approximately 0.1
second when the printer receives BEL code.
When one of the following
1.
Pee, Pee, Pee, Pee:
2. Pi, Pi, Pi, Pee:
3. Pi, Pi, Pi Pi, Pi, Pi:
4. Pi, Pi, Pi, Pi
(repeats 5 times):
-
errors occurs, the buzzer also sounds as follows.
Short circuit between the collector and emitter has
-
occurred. (4 long pip sounds)
Abnormally high voltage is detected. (3 short and
-
one long pip sounds)
An error has occured in the slave CPU. (3 con
-
tinuous short pip sounds repeated twice with a
pause.).
-
Paper-end status is detected. (4 continuous short pip
sounds repeated 5 times with a pause.)
-
For all the above errors except Paper-end error the buzzer always sounds,
regardless of the ON/OFF position of DIP switch pin 2-2.
-
If a n error other than 4 above occurs, contact your nearest EPSON dealer.

2.4 Paper-End Detector
(1) When the paper-end detector (a reed switch located on the paper guide)
detects that the paper supply is nearly exhausted, the printer informs to the
host computer that an error has occurred and the printing operation stops.
(2) In the paper-out status, the printer is automatically put in the OFF-LINE state
and paper advancement can be performed by depressing the LF or FF switch.
After setting new paper in the printer, depress the ON-LINE switch so that the
printer may resume operation.
(3) There i s another way to start the printer when it falls into paper-out status.
Set new paper in the printer, and turn the POWER switch OFF and ON again.
In this case, however, all previously established data such as TAB, line spacing,
etc., are cancelled.
(4) The paper-end detecting function is useful to prevent erroneous printing when
the printer is out of paper. If the printing is to be continued up to the last line of
the paper, the paper-end detecting function may be made invalid by either of
the following two methods.
-
1) Set the DIP switch pin 1-3 to the ON position, and the paper-end detecting
function will become invalid hardwarewise.
-
2) Enter control code ESC 8 to disable the paper-end detecting function by
software.
3) Feed a second sheet of paper in behind the first one after the first one has
passed part way through.
