3.6.3. LED Indicators

There are two LED indicators in the eXtendo
Fig. 2 and 3. The upper LED is red, and the lower one is green. (In some early
samples, the upper LED is also green. If you have such a sample, any time you see
reference to the "red" LED, you should consider that the "upper" LED.) These LEDs
are used to signal some status information concerning the eXtendo
following is a partial listing of the information supplied.
There are several flashing speeds used in the eXtendo
Slow: 0.5 Hertz (LED is "on" for one second and "off" for one second)
Medium: 5 Hz ("on" for 100 ms and "off" for 100 ms)
Fast (Flicker, or "F"): 10 Hz ("on" for 50 ms and "off" for 50 ms)

Please note that much more detailed information concerning the printer's current
state can be obtained by requesting the printer's status via the interface. Please refer
to the eXtendo

3.6.4. Head Status Sensor

An additional Head Status Sensor is used to determine whether the printhead is in
the up (do not print) or down (ready to print position). Normally, most of the heat
generated by thermal printing is transferred to the paper being printed and is removed
from the printer as the paper advances. When the printhead is up, no heat is being
transferred to the paper and the heat remains in the individual dots, allowing them to
overheat if activated repeatedly. Because this may cause permanent damage to the
printer, the eXtendo
The output of this sensor is also available from the Query function. See the eXtendo
Emulation Command Set Reference D 684 112 for details on determining the
printhead position and the printhead temperature.

3.6.5. Chute/Jam Sensor (Optional)

The optional chute/jam sensor continually monitors whether there is paper in the
chute, and can be read via the Status function. (Please see the eXtendo
Command Set Reference D 6840112 for details.) This function is often used in
conjunction with the host's peripherals to signal the user when a printout is not taken.
Examples where this is important include when the information is confidential, or the
printout can be redeemed for cash or items of value. This function can also be used
to prevent the host from sending a new print job until the printout from the previous
print job has been removed.
