the printer to discharge electrical static as it may cause malfunctions or
failures in the printer and the tester.

(1) Disconnect the power cord.
(2) Connect the connector 1 of the tester to the envelope feeder connector in the printer. The
seal on the connector 1 should be facing up when connected to the envelope feeder
connector. Connect it to the duplexing unit connector on the back to check the envelope
feeder operation. The seal on the connector 1 should be facing right (the left cover side)
when connected to the duplexing unit connector.
(3) Connect the power cord and operate the tester when the printer enters the standby mode.
Note that the connector of the tester fits into the connector on the wrong side.
