However, rather than embedding the associated Printer Serial Number (which currently is not
available) in the Encoder Device Name String the utility will display a “temporary” Printer Serial
Number equal to “Z9999999. This special Printer Serial Number will subsequently indicate to the
user that the device has not been completely configured.
Typically, a failure to establish an encoder session with the device will be due to one of three
primary reasons:
1.
The user provided an invalid IP Address or Printer Name.
2.
The network connection between the host and the printer is not working.
3.
The printer is not powered up or is offline.
If a failure to establish the temporary encoder session occurs, then prior to using the encoder for
the first time the user must manually complete the device configuration process. This process is
completed in following four steps:
1.
Identify and remedy the cause for the failure.
2.
Manually establish a temporary encoder session with the device.
3.
Terminate the temporary encoder session.
4.
Restart the encoder device.
Additional instructions for Steps 2 through 4 will be provided later in this document.
