93 Installation and Service Guide: Printer Controller EB-34
Troubleshooting
Troubleshooting
This chapter identifies the source of common problems that may occur with the EB-34 and suggests ways of correcting
the problems.
Troubleshooting process
Problems with the EB-34 configuration may occur in one of three areas:
• Inside the EB-34
• In the interface between the EB-34 and the copier
• In the interface between the EB-34 and the workstations or computers to which it is connected
This chapter does not attempt to provide troubleshooting information for attached computers such as PCs or Mac OS
computers, copiers, or extensive networks. Refer problems in these areas to the appropriate service departments and
network administrators.
The terms “replace” and “replacing” are typically used throughout this document to mean reinstallation of existing
components. Install new components only when necessary. If you determine that a component you have removed is
not faulty, reinstall it. Replacement parts and specifications are subject to change. Refer to the current parts list
maintained by your authorized service/support center. Install the correct parts as directed by your authorized
service/support center.
Preliminary on-site checkout
Most problems with the EB-34 are caused by loose board or cable connections. This section describes the quick
checks you can do to locate and fix obvious problems. It describes how to eliminate any problems with external
connections to the back of the EB-34, 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 EB-34, 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.
Caution:When performing the service procedures described in this chapter, follow the precautions listed in
page 9.
