4. Join the two paper feed units with two joint brackets (rear) [A] and one screw [B] (M3 x 6:
3 (included in this kit)).
5. Reassemble the mainframe and the paper feed units.
When installing the mainframe with two paper feed units, join the two paper feed units

first, and then join the mainframe with the paper feed units. However, if there is already a
machine with one optional paper feed unit, you can put a machine with a paper feed unit
on another paper feed unit, and join them (be careful if you do this, because the
mainframe with one paper feed unit is very heavy).
