EPC1800 SERIES OPERATION MANUAL
5.6.2- Hexadecimal dump mode
To enter this mode answer NO to the previous question
“Enter in configuration?”. It will be followed then by the question
“Enter hexadecimal mode?” to which YES must be answered.
Once entered this mode, which will be indicated by “***HEXADECIMAL MODE***” anything sent to
the printer will be printed as hexadecimal characters.
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.

5.7- ERROR PROCESSING
5.7.1- Error types
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 command or activating the automatic status reporting (See section
6 –
CONTROL COMMANDS
). 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: No paper / door open error, hardware error,
converter voltage error and printing head temperature error.
When any of these errors happen, the led blinks with a different blinking timing sequence and color
for each of them according to the figure below. If no error happens the led will light permanently green.
