Cleaning the Media Feed Rollers for Tray 2
Be sure to remove the duplex option before cleaning the media feed rollers 
for Tray 2.
1If the duplex option is installed, remove it.
If the duplex option is not installed and the locking pins are 
installed at the back of Tray 2, remove the locking pins (one in 
each opening on the left and right sides at the back of Tray 2).
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.
2Remove the dust cover from Tray 1 and close the tray.
3Lift the machine off of Tray 2 and 
temporarily place it on a sturdy 
flat surface.

5Lift the machine and reinstall it 
on top of Tray 2.
6Open Tray 1 and reattach the dust cover.
7If you removed the duplex option in step 1, reinstall it.
If the duplex option is not to be installed, install the locking pins.
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.
