Lexmark c750 安装指南

Attach the output expander paper 
bail to the top cover.

Go to "Step 3:  Set up the print 
supplies" on page 15.

Your printer supports a 5-bin mailbox 
that lets you collate and stack up to 500 
sheets of paper.

After you unpack the mailbox, 

install it immediately. Otherwise, the 
edges of the mounting brackets could 
damage tabletops or fabrics.

Unpack the mailbox and remove 
any packing material.
