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).

a. Single paper pass mode (with paper)
When documents are set on the paper feed tray, the document feed
LED lights up. When the push switch is pressed, all documents on the
paper feed tray are fed.
b. Duplex paper pass mode (with paper)
When documents are set on the paper feed tray, the document feed
LED lights up. When the push switch is pressed, all documents on the
paper feed tray are fed.
c. Single aging mode (without paper)
When the push switch is pressed, aging is started. The operation
timing is made by detection of each document size on the tray.
d. Duplex aging mode (without paper)
When the push switch is pressed, aging is started. The operation
timing is made by detection of each document size on the tray.
e. Load check mode
Set the DIP switch on the contro PWB as shown below, and open
and close the ADF/ RADF paper feed section cover to enter the load
check mode.
