3.3 IC-304 Print Controller Hardware Diagnostics
Software
The IC-304 print controller diagnostics software is used for testing both proprietary
Creo hardware (FusionIN) and standard off-the-shelf hardware.
There is JOIND (Java Over the Internet Diagnostics)—an IC-304 print controller
client/server diagnostic controller—that runs locally or over a TCP/IP connection.
JOIND runs under a Windows platform (NT/98/2000/XP) and enables local
diagnostic testing of IC-304 print controller products with user level support.
If you encounter any problems during installation or during normal operation of the
IC-304 print controller, run the IC-304 print controller diagnostics software to
determine the cause.
The diagnostic software is located on the IC-304 print controller. The software
receives and executes test requests and returns appropriate status responses.
A hierarchical diagnostics tree shows the FRUs (field replacement units) that can be
tested b
y JOIND (IC-304 print controller diagnostics software) . You can select an
individual component from the tree for testing, run batch tests of selected
components, or run a general test of all units by selecting the
DFE option.
Results appear as PASS/FAIL.
