„ Provide sufficient work space for disassembling and
reassembling.
„ Locate the printer on a stable and flat surface.
„ Be extremely careful to avoid a personal injury when moving
or carrying it as the printer is extremely heavy in weight. When
removing/reinstalling the feet from/to the main unit, the work
should be done by the number of people indicated below.
•
Stylus Pro 7400/7800: 49 kg (two or more persons are
required)
•
Stylus Pro 9400/9800: 90 kg (four or more persons are
required)
„ The ink-path-related components or parts should be firmly and
securely reinstalled on the printer to prevent the ink from
leakage.
„ Use only recommended tools for disassembly, assembly or
adjustment of the printer.
„ When air duster is used on the repair and the maintenance
work, the use of the air duster products containing the
inflammable gas is prohibited.
„ Apply lubricants and adhesives as specified.
„ Be careful not to soil the printer or the floor with the leaked ink
when removing the ink-path-related components or parts.
Spread a sheet of paper or cloth on the floor in advance.
„ Do not touch electrical circuit boards with bare hands as the
elements on the board are so sensitive that they can be easily
damaged by static electricity. If you have to handle the boards
with bare hands, use static electricity discharge equipment such
as anti-static wrist straps.
„ When reassembling the printer, make sure to connect the
connectors of the electric components or parts correctly and
securely. Use extreme care when connecting FFCs (flexible flat
cables). Improper connection of the FFCs, such as inserting
them diagonally into the connectors, could cause short-
circuiting and lead to breakdown of the electric elements on the
boards.
„ When reassembling the printer, make sure to route the FFCs
and other cables as specified in this chapter. Failure to do so
may cause an unexpected contact of the cables with sharp metal
edges, or lead to lower the noise immunity.

„ When the printer has to be operated with the covers removed,
take extra care not to get your fingers or clothes caught in
moving parts.
„ The cutter blade is razor-sharp. Be especially careful when
handling the cutter.
„ Carbide blade employed for the cutter blade is hard but brittle.
Be careful not to hit it against metal parts of the printer as it
can be easily damaged.
„ When you have to remove any parts or components that are
provided as after-service-parts but are not described in this
chapter, carefully observe how they are installed and make
sure to remember it before removing them.
„ When you removed any parts or components that are secured
with black acetate tape or two-sided tape, be sure to reinstall
and secure them with the tape as exactly the same as they were.
