Use the following table to interpret the LEDs and find the source of the problem. Remember that you should read these LEDs when you push the Power button.

Some combinations may require the replacement of two or more components. In this case, always replace one component at a time. Test the printer to see if the problem has disappeared (check the LEDs again). If the same LED sequence continues, replace the next component indicated in the
