XF
eXtendo®
Thermal Printer Family
The through-beam sensor can also be used in a manner similar to a Black Mark sensor.
Instead of a Black Mark, a hole or slit cutout in the paper is used. The through-beam sensor
is located around the centerline of the paper path. This is the only location it may use. See
→ chapter 10.2.
3.5.2 Status Indicator
There is a two-color status indicator in the eXtendo® XF series printers, located on the rear
side (see Fig. 2). It is used to signal the current status of the eXtendo® XF printer. There are
several flashing speeds used in the printer LEDs. These are:
Slow:
Medium:
Flicker (F): 10 Hz

Please note that much more detailed information concerning the printer's current state
and sensor conditions can be obtained by requesting the printer's status (→ eXtendo®
Emulation Command Set Reference D 684 112) or by using the eXtendo® Diagnostic Tool.
3.5.3 Printhead Status Sensor
An additional Head Status Sensor is used to determine whether the printhead is in the
unlocked or locked position (ready to print). Normally, most of the heat generated by
thermal printing is transferred to the paper being printed and so is removed from the head
as the paper advances. When the printhead is in unlocked position no printing or paper
loading is possible.
The output of this sensor as well as the current printhead temperature is also available
through various query functions.
3.5.4 Exit Sensor
The exit sensor located in the chute continually monitors whether there is paper in the
chute and can be read via the status request function. This function is often used in
conjunction with the host's peripherals to signal the user when a printout has not been
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 taken away.
