When installing Tray 2 without installing the duplex option, also install the 
locking pins (one in each opening on the left and right sides at the back of 
Tray 2).
While holding the grip of the locking pin vertical, insert the locking pin into the 
opening on either the left or right side of the lower feeder unit and, while 
pushing it in, turn it to either the left or the right. The locking pin is installed 
when its grip is horizontal.
Installing the left and right locking pins secures the lower feeder unit to the 
machine so it cannot be removed.
"
This step can be skipped if the duplex option is to be installed after 
installing Tray 2.
"
To uninstall the lower feeder unit from the machine, remove the locking 
pins on the left and right side at the back of Tray 2, and then remove the 
lower feeder unit. To remove a locking pin, turn it to either the left or the 
right so that its grip is vertical, and then pull out the locking pin to remove 
it.
