Service approach
Product repair normally begins by using the product internal diagnostics and the following two-step
process:
1.Isolate the problem to the major system (for example, the network or server, or the product).
2. Troubleshoot the problem by using the procedures in chapter 6.
After you find a faulty part, the product 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.

7.Send a print job from the host computer, and then verify that the output meets expectations.
8. If necessary, restore any customer-specified settings.
9. Clean the outside of the product with a damp cloth.
