SC-F9200 Series

The power switch for this printer is installed on the secondary
W A R N I N G
side of the power circuit; therefore, the power is always
supplied unless the power cable is unplugged. To prevent
electric shock and circuit damage during servicing, make sure
to follow the instructions below.
•
Before removing a circuit board, make sure to unplug the
power cable from the AC outlet. Then press the power
button on the operating panel to confirm that the LEDs go
on and off. This operation discharges the residual charge in
the printer.
•
Make sure not to place the removed circuit boards on the
metal and such directly.

Always wear gloves for disassembly and reassembly to avoid
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 physician.

When replacing the Main Board, Power Supply Board, or
Power harnesses and such, make sure to visually check if any
harness is caught in between or any wrong connection exists.
DISASSEMBLY & ASSEMBLY

Locate the printer on a stable and flat surface.
C A U T I O N

Use only recommended tools for disassembly, assembly or
adjustment of the printer.

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 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.

Disassembling the frame and the PF shaft of the printer is
prohibited because they are assembled with precise
measurements in 1/100 mm unit at the factory.
