3.5- ERROR PROCESSING
The TK23 can detect several errors. These errors are indicated in different ways
depending on their relevancy and on the communications interface used (serial or
parallel).
There are two ways of indicating these errors:
•
SERIAL PORT:
When an error occurs, the DTR signal goes to active level
(logical “HIGH” level). If the user detects that this signal is “high”, that means
that an error has occurred. The TK23 can send the STATUS BYTES by the
serial port, to communicate some of these errors (command
DEL EOT
), in
RS232 protocol.
•
PARALLEL PORT:
When a No Paper / Head-Up error occurs(see 3.5.1), it is
indicated in the PE and /ERR signals. If a generic error ocurrs, it is indicated in
the /ERR signal. Paper-Near-End sensor can be signaled in the PE signal by
using Control Commands (see 3.5.2).
NOTE:
(1) For more information on how each error is indicated see points 3.5.1 to
3.5.8, here every error is explained in detail.
Name Description
NO PAPER
There is no paper in the printer inlet
HEAD-UP
The thermal head is open
PAPER-NEAR-END
The paper roll is near its end
HEAD TEMPERATURE The thermal head temperature is above 75ºC
CUTTER
The autocutter can not cut
VOLTAGE
The thermal head voltage is out of range (Vp = 24V
±
10%)
HARDWARE
There is an error in the control board interface
OPTICAL MARK
The optical mark is not detected
NO ERROR
There is no error
Table 3.1-
Errors explanation.
3.5.1- NO PAPER / HEAD-UP ERROR
Although these two errors have different causes, they are indicated in the same way
because the action to recover from these errors is actually the same. This error is quite
significant, so when it arises the motor stops and no printing is allowed.
•
ERROR ORIGIN: There is no paper in the printer inlet or the thermal head is open.
•
LEDS INDICATION: The PE led turns ON.
NOTE:
(1)
This error is indicated in the parallel port depending on the conditions set by
the
”ESC c 3”
command (See point
4. CONTROL COMMANDS
).
•
RECOVERY: To recover from this error, user must do a paper load
(See point
3.1- LOADING PAPER
), or turn down the head lever.
