2. 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.
