3.1 Precautions for Parts Replacement
(1) Before starting the parts replacement, remove the AC power cord and interface cable.
(a) Remove the AC power cord in the following sequence:
i) Turn off ("o") the power switch of the printer.
ii) Disconnect the AC inlet plug of the AC power cord from the AC receptacle.
iii) Disconnect the AC power cord and interface cable from the printer.
(b) Reconnect the printer in the following sequence.
i) Connect the AC power cord and interface cable to the printer.
ii) Connect the AC inlet plug to the AC receptacle.
iii) Turn on ("l") the power switch of the printer.
(2) Do not try to disassemble as long as the printer is operating normally.
(3) Do not remove parts which do not need to be touched; try to keep the disassembly to a
minimum.
(4) Use specified service tools.
(5) When disassembling, follow the procedure in sequence laid out in this manual. Parts may be
damaged if these sequences are not followed.
(6) Since screws, collars and other small parts are likely to be lost, they should temporarily be
attached to the original positions during disassembly.
(7) When handling IC's such as microprocessors, ROM's and RAM's, or circuit boards, do not
wear gloves that are likely to generate static electricity.
(8) Do not place printed circuit boards directly on the equipment or floor.
