Service approach
Table 2-1. Printer repair normally begins by using the printer’s internal diagnostics
and the three-step process below.
Step 1 Isolate the problem to the major system (for
example, the host computer, the network or
server, or the printer system).
Step 2 Determine if the problem is located in the
accessories or in the printer engine.
Step 3 Troubleshoot the problem using the procedures
in Chapter 7.
Once a faulty part is located, the printer can usually be repaired at the assembly level by
replacing field replaceable units (FRUs). Some mechanical assemblies might need to be
repaired at the subassembly level. Hewlett-Packard does not support replacement of
components on the printer circuit assembles.
