1. Replacement and Adjustment
Beforehand
• Before installing options, please do the following:
If there is a fax unit in the machine, print out all messages stored in the memory, the lists of user-
programmed items, and the system parameter list.
If there are printer jobs in the machine, print out all jobs in the printer buffer.
Turn off the main switch and disconnect the power cord, the telephone line, and the network cable.
• 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 breaks which can cause an injury, because the handle cannot hold the
mainframe’s weight.
• Always touch a grounded surface to discharge static electricity from your hands before you handle SD
cards, printed circuit boards, or memory boards.
