6.3 Hex Dump Mode
The Hex Dump Mode is a useful tool for diagnosing problems, including communication and DPL™
syntax errors, allowing a comparison of input strings (sent by host) to output data (received by printer).
To decode this information, the Class Series Programmer’s Manual is an essential reference. This output
can be used for debugging the label format. In addition, by repeatedly sending a format, this mode can
uncover handshaking problems (if they exist). Handshaking problems are identified by sections of
missing data in the character string.
To begin, go to the Diagnostics menu and enable Hex Dump Mode; see Section 4.2.7. Exit the menu and
save the changes. Now, ‘HEX DUMP MODE’ will be indicated on the display and all data sent to the
printer will now be output in hexadecimal code, along with the printable ASCII equivalents.
The figure below is a sample Hex Dump Label. After sending a label format to the printer, the hex code
output will be immediate. As a final note, many software programs use bit mapping to construct the label,
making diagnosis difficult. Contact Datamax Technical Support with any questions.
 Note: To return to Ready Mode, re-enter the Diagnostics Menu and disable the Hex Dump Mode, exit the menu
and save the changes.
