18 Chapter 2: Diagnostics and Configuration

Diagnostics modes

To change the diagnostic modes enter the configuration menu, select "Set Diagnostics 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. There are DataScope modes for both with and without graphics.
• Receipt test: the receipt printer prints all 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," page 16 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 "Diagnostics Modes" sub-menu of the configuration menu.
Press the paper feed button as instructed on the "Diagnostics Modes Menu" to enable or disable the data scope mode test.
• Off, normal mode (Data scope mode disabled)
• Data scope mode with or without graphics (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.
2 Disable the data scope mode.
3 Exit the configuration menu.
The printer is on-line and can communicate normally with the host computer.
