Always wear gloves for disassembly and reassembly to avoid
W A R N I N G
injury from sharp metal edges.
If ink gets in your eye, flush the eye with fresh water and see a
doctor immediately.
Never touch the ink or wasted ink with bare hands. If ink
comes into contact with your skin, wash it off with soap and
water immediately. If irritation occurs, contact a doctor.
When replacing the Main Board, Power Supply Board, or
Power harnesses and such, make sure to check visually if any
harness is caught in between or any wrong connection exists.
Ensure sufficient work space for servicing.
C A U T I O N
Locate the printer on a stable and flat surface.
The ink-path-related components or parts should be firmly and
securely installed on the printer to prevent ink from leakage.
Use only recommended tools for disassembly, assembly or
adjustment of the printer.
When using compressed air products; such as air duster, for
cleaning during repair and maintenance, the use of such
products containing flammable 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.
DISASSEMBLY & ASSEMBLY
When reassembling the printer, make sure to route the FFCs
C A U T I O N
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.
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.
Disassembling the frame and some components of the printer is
prohibited because they are assembled with precise
measurements in 1/100 mm unit at the factory.
