Disassembly and Assembly

4.1.1 Precautions

See the precautions given under the handling "WARNING" and "CAUTION" in the
following column when disassembling or assembling the Stylus C40UX/C40SX/
C20UX/C20SX.
Disconnect the power cable before disassembling or assembling
the printer.
If you need to work on the printer with power applied,
strictly follow the instructions in this manual.
Wear protective goggles to protect your eyes from ink. If ink gets
in your eye, flush the eye with fresh water and see a doctor
immediately.
Always wear gloves for disassembly and reassembly to avoid
injury from sharp metal edges.
To protect sensitive microprocessors and circuitry, use static
discharge equipment, such as anti-static wrist straps, when
accessing internal components.
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 a lithium battery is installed on the main board of this
printer, make sure to observe the following instructions when
serving the battery:
1. Keep the battery away from any metal or other batteries so that
electrodes of the opposite polarity do not come in contact with
each other.
2. Do not heat the battery or put it near fire.
3. Do not solder on any part of the battery. (Doing so may result in
leakage of electrolyte from the battery, burning or explosion. The
leakage may affect other devices close to the battery.)
4. Do not charge the battery. (An explosion may be generated inside
the battery, and cause burning or explosion.)
5. Do not dismantle the battery. (The gas inside the battery may hurt
your throat. Leakage, burning or explosion may also be resulted.)
6. Do not install the battery in the wrong direction. (This may cause
burning or explosion.)
Danger of explosion if the battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by
the manufacture. Dispose the used batteries according to
government's law and regulations.
