Error Processing - Fenix TS2000 Series Operation Manual

5.8.2- Hexadecimal dump mode
To enter the hexadecimal mode, proceed in the same way as in the continuous self-test, but
keeping pressing the button until printing "Enter in hexadecimal
mode?...".
Then continue with the button pressing for four seconds
until the text "~~~ HEXADECIMA MODE ~~~" has been
printed.
This mode can be very helpful for the application developer during the setup test time, as it allows
detecting possible errors (like out of range parameters, non valid command sequences, errors in the
communication channel, etc.), comparing what it has theoretically been sent to the printer to what it is
really being received.
Turn off the printer to quit the hexadecimal mode.
NOTES:
(1) For any received characters under 20h, the ASCII
'.' will not be printed.
(2) During the hexadecimal dump mode, the DEL EOT
command does not work.
(3) It must be taken into account that if the number of
bytes is less than the minimum amount required to
print one line (9 bytes), the printer will not print. It is
recommended to complete the hexadecimal dump
by sending at least 9 bytes (for example 00h).
(4) It is also possible to enter the hexadecimal mode
through the GS (A command.
5.9. E RROR PROCESSING
When an error occurs, the printer visually notifies its type through the LED. This fact allows the
final user to have a direct and visual reference of the current printer status.
On the other hand, the printer status and all its possible errors can also be monitored via software
through the "DEL EOT n" command or activating the automatic status reporting "GS a n" command. In
this way, the application developer can have more complete information on the printer status, therefore
being able to act accordingly.
FENIX recommends that developers include in their applications a flow chart like the one shown
below, to have monitored the printer.
