Chapter 3 Installation
Controls and

Control Lamps
The EasyCoder F4 has several ways of communicating directly with
its operator: three control lamps, a display window, a membrane-
switch keyboard with 22 programmable keys, a big programmable
“Print” button on the printer’s front, and a beeper.
The control lamps are colored LEDs (Light Emitting Diodes) and
are used for the following purposes:
• Power (green) indicates that the power is on.
• Ready (green) indicates that the printer is ready for use.
• Error (red) indicates that some kind of error has occurred. If
serial communication is used, an error message may be returned
to the host computer.
The display window contains an LCD (Liquid Crystal Display)
with background illumination and two lines of text, each with 16
characters. It guides the operator through the setup and indicates
possible errors during printing.
The Intermec Fingerprint programming language and the Intermec
Direct Protocol allow custom-made messages to be composed and
displayed according to the requirements of the application.
The keyboard is of the membrane-switch type and has 22 keys.
The keyboard is supplemented by a large “Print” button on the
printer’s front. Some keys have hard-coded functions in the startup
and setup modes.
In application programs created by the Intermec Fingerprint
programming language, the keys can be assigned various functions.
Since one key works as a shift key, up to 44 different key combina-
tions are possible. An audible signal, which can be turned off,
acknowledges that a key has been pressed.
