Troubleshooting Connector J136 Locator - 36
Connector J136 Locator
J136 is the connector that the envelope feeder mates into. To see
it, open the multipurpose tray and remove the closure panel. The
illustration below shows the connector as it appears from the
outside of the printer.
A voltage reading of 24V between pins 1 (+24VA) and 4 (GND)
during printer startup indicates that motor power is reaching the
envelope feeder.
