Diagnostic modes
To change the diagnostic modes enter the configuration menu, select “Set Diagnostic Modes” from the main menu and
select one of the following modes:
• Normal: normal operating mode of the printer.
• Datascope: the receipt printer prints incoming commands and data in hexadecimal format to help troubleshoot
communication problems.
• Receipt test: the receipt printer prints two code pages to verify proper printing of the receipt.
Caution: Be extremely careful changing any of the printer settings to avoid inadvertently changing other settings that
might affect the performance of the printer.
See “Configuring the printer,” for instructions on how to enter the configuration menu.
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.
2 Run a transaction from the host computer.
All commands and data sent from the host computer will be printed as hexadecimal characters as shown in the
illustration.
To exit the data scope mode:
1 Enter the configuration menu again.
See “Configuring the printer.”
2 Disable the data scope mode.
3 Exit the configuration menu.
