Printer 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, server, or the product).
  2. Troubleshoot the problem by using the procedures in the HP LaserJet Pro M701/M706 Troubleshooting

Manual.

After you locate a faulty part, the product can usually be repaired at the assembly level by replacing FRUs. Some mechanical assemblies might need to be repaired at the subassembly level. HP does not support replacement of components on the printed circuit assembles. Before performing service

CAUTION: If this warning is not followed, severe injury and damage to the device can result. The power must be on for certain functional checks during troubleshooting. However, the power supply must be disconnected during parts removal.
  2. Remove all media.
  3. Place the product on an ESD mat (if available).
