7.3 Character Dump Mode
The character dump mode is a useful tool for diagnosing various
printer problems, communication problems, or DPL syntax errors.
This procedure allows the user to input strings of data and compare
them with the output from the printer. In many cases, the
Programmer’s Manual is an essential reference. Also, as a final
note, many of the software programs use bit mapping to construct
the label, making a diagnosis difficult. Always contact a Technical
Support Representative with any questions.
With the printer ‘Off’, print a Configuration Label using the power-
up method:
n Press and hold in the Feed button while turning the printer ‘On’.
o Release the Feed button when the printer display reads
'DYNAMIC RAM DIAGNOSTICS'...
p The printer will print a set of Configuration Labels and then
enter the Character Dump Mode.
Figure 7-1 shows a sample Character Dump Label. Send a label
format to the printer. The hex code output will be immediate. This
output can be can be used for debugging the label format. Also by
repeatedly sending the format, this mode can uncover handshaking
problems (if they exist). Handshaking problems are identified by
sections of missing data in the character string.

it ‘off’ and then ‘on’.
