Attaching the input tray and output tray supports
1.Place the right side hole of the input tray over the mounting post as shown below. Then push the paper tray’s left side notch onto the mounting post until it snaps in place.
2.Install the output tray supports into the notches provided for them.
Each support is marked with an L or R on one of its tips. Install the L support into the two leftmost notches, first inserting the long tip into the first notch on the left and slightly twisting the support to insert the other tip. In a similar fashion, insert the R support.
