Troubleshooting
The imagePRESS Server is a server for printers, and is generally part of a configuration that has connectivity to the printer and
workstations or computers. Problems may occur in one of three areas:
• Inside the imagePRESS Server
• In the interface between the imagePRESS Server and the printer
• In the interface between the
imagePRESS Server
and the workstations or computers to which it is connected
This chapter identifies the source of common problems that may occur with the imagePRESS Server and suggests ways of
correcting them. This chapter does not attempt to provide troubleshooting information for attached computers such as Windows
or Mac OS computers, printeres, or extensive networks. Refer problems in these areas to the appropriate service departments
and network administrators.
If network administrators need to troubleshoot job errors that occur with Command WorkStation, refer them to Configuration and
Setup for more information, including how to use the Job Error Report feature to collect error information to send to Technical
Support.
IMPORTANT:
When performing the service procedures described in this chapter, follow the precautions listed in “Precautions ” on page
3 .
Preliminary on-site checkout
Most problems with the imagePRESS Server are caused by loose board or cable connections. This section describes the quick
checks that you can do to locate and fix obvious problems. It describes how to eliminate any problems with external connections
to the back of the imagePRESS Server, and then addresses checking internal board and cable connections. Check external and
internal connections before replacing any components.
NOTE:
Verify that the network is functioning, no unauthorized software or hardware is installed on the imagePRESS Server, and no
problems have occurred with a particular print job or application. The on-site administrator can help you verify these issues.
For problems that persist after you check the external and internal connections, this section provides a comprehensive list of
internal and external checks that may help you fix the problem.
