Chapter 4 : Troubleshooting and General
Procedures
Use this troubleshooting or fault isolation procedure as the starting point in diagnosing the
DEClaser 3500 printer.
Because the DEClaser 3500 servicing strategy is based on Return to Digital (RTD), this
troubleshooting procedure represents the basic procedure to determine if the customer should
return the printer for servicing.
Determine the kind of problem that exists and diagnose the problem as soon as possible. Is the
problem a printer problem, a known bug, or a non-printer problem? For example:
• A bad power supply requires RTD or on-site FRU replacement.
• The inability to print a hardware report from the front tray is a known bug or limitation of the
printer, requiring no service
• Incorrect installation of hardware or software is a non-printer problem and requires no
service action.
The general troubleshooting process begins by determining the symptoms and following a
systematic approach. The following block diagram illustrates the systematic fault isolation
procedure.
