6.1 Overview
This chapter provides information on how to maintain the printer in its optimum
operating condition.
Basically, servicing on the printer should be performed on-site. Be sure to strictly
observe the following precautions to avoid an accident
or injury causing the user
trouble.
•
•
The power switch is installed on the secondary side of the
power circuit, so power is always supplied to the power supply
circuit even when the switch is OFF unless the two power cords
are unplugged from the wall power outlets. Unless otherwise
stated (for printing or operation checks), be sure to unplug the
two power cords from the wall outlets before disassembling or
assembling the printer to prevent electric shock and damage to
the circuit .
A
lithium battery is mounted on the Main Board (control
circuit) for memory backup . Be sure to observe the following
precautions when handling the lithium battery .
• Be careful not to short the electrode of the battery .
• When replacing the battery, make sure to insert it in correct
orientation.
• Never heat the battery or plunge it into the flames.
• Do not put the Main Board directly on conductive materials .
Be
extremely careful not to get the ink into your eye or let it
come into
contact with your skin. If it happens, wash out your
eye or skin with water immediately. If any abnormality is
found, contact a physician.

Ensure sufficient work space for servicing.
The printer weighs approx. 183kg. When the printer needs to
be
~oved, make sure to lift or carry it using the carrying bars
by SIX people. (refer to "6 .2.2 Transportation" (p222) )
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 .
Be
sure to spread a sheet of paper or cloth on the work space
before removing any ink-path - related parts or components to
keep
the space from being soiled with leaked ink.
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 such as the drive gear unit or carriage unit.
When the printer needs to be repacked for transportation after
being used, make sure to follow the steps below after turning
the power OFF.
1. Check that the PRINT HEAD is capped properly .
2. Dispose
of waste ink from the ink drain tank .
3.
Remove all the cables including the power cords .
4. Loosen
the adjusters of the Stand .

6.2.2 Transportation
When detaching the body section of the printer from the Stand, follow the steps below.
I. Insert the two carrying bars into their carrier holes (nvo each) at the bottom of the printer.
2. Verity that the bars are inserted until the heads
of the screws touch the carrier
holes. then turn the bars so that there
is a sc rew head in both sides of the carrier
hole's sides. (This prevents the bars from sliding during the transport.).
Figure 6-2. Preparation to Carry the Body Section
3. Lift the body section using the carrying bars by six people to remove it from Stand.
Figure 6-3. Detaching the Body Section
CAUTION
I
•
For the transport, if 950ml cartridges were used, they should be
removed from the printer and transported "flat", wider side down
as vibrations could make the weight of the ink moving inside the
pocket causing premature wear of the pocket lower side when the
cartridge is transported on its narrow side (insertion position). If
this cannot be guaranteed, the 950ml used cartridges should not be
transported and discarded instead, as a precaution. (New
cartridges, cleaning cartridges and initial charge ink cartridges can
be transported in any direction.)
