2) Disconnect the connector from the CN9 on the control PWB, and

connect the short connector (OCW4074K526//) instead.

3) Remove the ADF/RADF top cover, and set the DIP switch on the

control PWB to the desired test mode. While pressing the push
switch ON, turn on the power of the machine. 

(With the above operation, the machine enters the test mode.)

4) Turn on the push switch on the control PWB.

(Test operation is started.)

(To switch to another test mode, set the DIP switch on the control
PWB to the desired test mode, and open/close the ADF/RADF paper
feed section cover (microswitch FGOD it turned OFF and ON).
