Preliminary on-site checkout
Most problems with the ColorPASS are caused by loose board or cable connections;
therefore, this section describes the quick checks you can do to locate and fix obvious
problems. This section first describes how to eliminate any problems with external
connections to the back of the ColorPASS, and then addresses checking internal board
and cable connections. It is a good idea to check external and internal connections before
replacing any components.
NOTE: First, verify that the network is functioning, no unauthorized software or hardware
is installed on the ColorPASS, and there are no problems with a particular print job or
application. The on-site administrator can help you verify these issues.
For problems that persist after you have checked the external and internal connections,
this section goes on to provide a comprehensive list of internal and external checks that
may help you fix the problem.
This section includes the following:
• “Checking external connections” on page 5-3
Describes the quick checks you can do to make sure the problem is not caused by a
loose connection at the back of the ColorPASS.
• “Checking internal components” on page 5-4
Describes the quick checks you can do to make sure the problem is not caused by a
loose board or cable connection inside the ColorPASS.
•“Inspecting the system” on page 5-5
Provides a more comprehensive checklist for checking the ColorPASS internally and
externally. If your initial checks fail, you may want to go through this checklist before
concluding that you need to replace a cable or component.
