TK14 OPERATION MANUAL
21/65
3.4- OPEN PLATEN SENSOR
When this sensor detects the opening of the platen, it lights the orange LED, blocking all the activity
related to printing.
NOTE: If TK14 detects no paper or platen open while is printing, the current and the following data
will be lose. The control error must be done before sending any byte data. ( See 3.7.4 and
3.7.5 points, flow diagrams of the error detection).
3.5- LED INDICATOR
TK14 has one indicator led to visually inform the printer status.
The led lights GREEN whether the TK14 is powered on without errors.
The led lights ORANGE whether the TK14 does not have paper and/or the platen is opened.
The led lights RED (BLINKING) if there has been any error in the TK14 (See section:
3.7- ERROR
PROCESSING
).
3.6- SPECIAL PRINTING MODES
Besides the normal printing mode, in which all the received data are printed according to the settings or
conditions fixed by the commands, the TK14 printer allows two special working modes: the self-test mode,
programming mode and the hexadecimal mode.
Fig. 3.5-
SELF-TEST mode example.
3.6.1- Self-test mode
The TK14 provides the self-test mode with
two different functionality: showing information on the
features of that particular printer model and verifying
the printing.
To enter the self-test mode, the printer must be
powered on while keeping pressed the paper
advance button (FEED).
The TK14 will start printing a report, which
allows checking the features of this particular
model, like the firmware current version, control
functions of the communications protocol, and so on.
If, once this printing has been finished, the
FEED is still kept pressed, the TK14 will start printing
continuously and repetitively a character map
until it finally concludes the self-test by printing
‘* * completed * *’.
This second option of the self-test mode has the goal to
validate the printing speed and quality.
