Diagnostics and Print Tests

5.Run the program that implements the download protocol. The program leads you through the download process.

Note: This program must be installed on the host computer or to a computer that is connected to the printer for diagnostic purposes.

6.Turn the printer off and reset the DIP switches to what they were when you started.

7.For normal operation settings, see “Switch Settings” in section 5. Turn the printer back on.

Data Scope Mode

Data scope mode is used to check communication between the printer and the host computer. When in data scope mode, the printer is configured for normal operations and receives all communication from the host computer. Instead of performing the commands however, the printer prints them in hexadecimal format on the receipt in the order they are received. For example, “1” prints as hexadecimal 31, “A” prints as hexadecimal 41, and so on.

Enter Data Scope Mode

Caution

The DIP switches are set at the factory to predetermined settings. Change the settings carefully to avoid changing other functions. Run the Diagnostic Print Tests to see if the Data Scope mode is on or off. For more information, see “Diagnostic Print Tests” later in this section.

Note: Secure the roller assembly in a closed position to eliminate the nuisance noise from occurring when the receipt take-up assembly is not being used.

1.Turn the printer off.

2.Turn the printer to the back to access the DIP switches and write down the current switch settings.
