3.7- ERROR PROCESSING
3.7.1- Error types
When an error happens, the TK14 visually notifies the error type through the led, located
next to the
buttons. This fact allows the final user to have a direct and visual reference on the current printer status.
On the other hand, the printer status and all its possible errors can also be obtained via software through
the
DEL EOT
command. In this way, the application developer can have more complete information on
the printer status, therefore being able to act accordingly.
The errors detected by the interface are the following: ‘near-end paper’, hardware error, power supply
voltage error and printing head temperature error.
When any of these errors happen, the led blinks with a different blinking timing sequence for each of
them. If no error happens the led will light permanently green.

NEAR-END PAPER ERROR
[Description]
This error happens when the ‘near-end paper’ sensor detects that the paper roll is close to
be finished. This means that using a paper roll with an external diameter of
80 mm
and
inner diameter of
25 mm
, the sensor will trigger the error when there are still
10 meters
of
paper approximately.
[Recover action]This indication should be really taken as a
warning
, not as an error as such. The action
depends on the application and the developer’s criteria. To recover from this error, user
must change the paper roll.
[Notes] Depending on the settings of command
“ESC c 4”
this error stops the printing or not (see
point
4. CONTROL COMMANDS
). If this error is set to stop the printing, it will be
detected as any other error. If this error is not set to stop the printing, user must detect it
by polling the status bytes. This error is indicated in the parallel port depending on the
conditions set by the
”ESC c 3”
command (See point
4. CONTROL COMMANDS
).
