6.1.1 Overview

This chapter consists of two sections: diagnosis and action. If you do not know the
possible cause of the problem, consult the diagnosis section first. If you know the
possible cause of the problem, skip to the action section.

6.1.2 Notes on troubleshooting

1. Before starting diagnostic procedures, ensure that all connectors and ribbon cables
are correctly connected.
2. If you are diagnosing the problem with the printer's covers removed and with power
supplied, be careful not to get an electric shock from the power supply or short-
circuit the PC boards.
3. The flowcharts use the following symbols:
Start/End
4. If you have replaced or repaired a part, be sure to make a test print to check that
the problem is corrected. If the indicated measures of a specific step still fail to
correct the trouble, try again, skipping to the next step.
