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. Before performing service ● Remove all media from the product. ● Turn off the power using the power switch. ● Unplug the power cable and interface cable or cables. ● Place the product on an ESD workstation or mat, or use an ESD strap (if one is available). If an ESD workstation, mat, or strap is not available, ground yourself by touching the sheet-metal chassis before touching an ESD-sensitive part. ● Remove the print cartridges. See Print cartridge on page 52 . ● Remove the tray cassette or cassettes. See Tray cassette (Tray 2, Tray 3, or Tray 4) on page 54 . After performing service ● Plug in the power cable. ● Reinstall the print cartridges. ● Reinstall the tray cassette or cassettes. ● If an optional paper feeder was installed, place the product on the feeder. Post-service test Perform the following test to verify that the repair or replacement was successful. Print-quality test 1. Verify that you have completed the necessary reassembly steps. 2. Make sure that the tray contains clean, unmarked paper. 3. Attach the power cord and interface cable or interface cables, and then turn on the product. 4. Verify that the expected start-up sounds occur. 5. Print a configuration page, and then verify that the expected printing sounds occur. 6.
