Enable or disable data scope mode
The data scope mode test prints a hexadecimal dump of all data sent to the printer: "1" prints as hexadecimal 31, "A" as
hexadecimal 41 and so on. This helps troubleshoot communication problems and runs during a normal application (after
being enabled through printer configuration).
Note: Data scope mode is usually considered a level 1 diagnostic test.
Data scope mode is enabled and disabled by selecting the "Diagnostic Modes" sub-menu of the configuration menu.
Press the paper feed button as instructed on the "Diagnostic Modes Menu" to enable or disable the data scope mode test.
• Off, normal mode (Data scope mode disabled)
• Data scope mode (enabled)
Note: Press the paper feed button for at least one second
to validate the selection.
To run the data scope mode:
1 After you have enabled the data scope mode, exit the
configuration menu.

All commands and data sent from the host computer
will be printed as hexadecimal characters as shown in
the illustration.
