Service Level Troubleshooting 3-78
Level 1 Diagnostics (Printer Configuration)
Level 1 diagnostics (setup mode) provides the functionality to change the settings for
various printer functions.
Take note of the following information when changing the settings:
• The default options are set at the factory and are stored in the history non–volatile
memory.
• After the settings are changed and stored in the non–volatile memory, the diagnostic
setup is exited, which saves the settings.
Caution: If you are changing the printer settings, make sure to add the correct settings
for that particular function or test to avoid accidentally changing the settings for another
function or test. If the settings are accidentally changed, re–enter the setup mode, and
then re–enter the correct settings. If you need assistance, contact a service representative.
For more information, refer to
Contacting a Service Representative on page 75.
Configuring serial port number assignments
This section describes how the NCR USB solution assigns serial port numbers (for
example, COMx) to the printer. The information that determines the assigned port
number is stored in the host computer and not in the printer. This assignment is made
in one of three ways. The first method is the default method that automatically assigns a
serial port number to the printer. The other two methods require users to specify a port
number. These methods are described more fully in the following section.
Serial port configuration methods
Automatic (Default)
When the printer is plugged into the USB port of the host and the drivers are loaded,
the printer will default to the next available serial port number. In many cases, this is
exactly what is desired. You can check the assigned serial port by clicking the General
tab in the Edgeport utility. You’ll see an entry for the NCR printer. Expand the list to see
which serial port has been assigned to the printer.
Assigning a serial port to the printer
If the default assignment does not meet the requirements of the installation, you can
assign a different serial port to the printer. From the General tab of the Edgeport utility,
select the printer and press Configure. Follow the directions on the resulting form to
assign a new port to the printer.
