 - Put the optional paper feed unit on the paper feed unit that was fitted with the bracket [A] in step 1.

 - Reassemble the mainframe and the paper feed units.

- Do not lift the machine together with one or more paper feed unit(s):
If there is already a machine with one or more optional paper feed unit(s), be sure to disconnect the machine and paper feed unit(s), and lift them up separately when moving/transporting. Otherwise, the handle of the paper feed unit will break due to the mainframe’s weight, and it can cause an injury. 
  
- 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.
