n
Before servicing or performing maintenance on the printer,
make sure you have enough space. If you need to move the
printer, be sure the space you move to is safe.
n
Because the printer is much heavier than most printers (about
43.5Kg for the printer body/ 52Kg for the printer and stand), you
need to take extra care. If you need to take apart the printer and
stand or lift the printer, two people are necessary.
n
If you remove the ink path system parts and replace them, run
the "Inter-User Transport Mode" and discharge the ink.
n
As necessary, after discharging the ink using the above method,
carry out ink initial filling using the "Transport Fluid Cartridges
(x 6 cartridges), then discharge the transport fluid in the Inter-
User Transport Mode to clean the ink system even more
thoroughly.
n
After removing any of the ink related parts, double check to
make sure all parts are secured; otherwise you're going to be in
big trouble.
n
Ink may leak onto other printer parts or the printer basket when
removing printer parts, so it is recommended to put a sheet or
cloth under the printer, especially when working on or near ink-
related parts.
n
When working on the electrical circuit boards, be careful
concerning static electricity which can cause damage to the
board. It is recommended you use an anti-static wrist band or
similar grounding device to prevent static electricity buildup.
n
When removing/re-inserting the flat-cable (FFC) from/to a
connector, make sure to pull/insert the cable at a 90 degree angle
to the connector. Otherwise, internal contact of the leads may be
damaged and this can cause a short-circuit.
n
When replacing connector wires, be careful to replace the entire
length of the wire exactly as you found it; rubbing against edges
or moving parts can cause noise in the wires.
n
As necessary, if you remove each cover operate the printer, care
should be taken not to get injured by the operation of the drive
system units.
Disassembly & Assembly
n
The cutter blade is extremely sharp, so care should be taken not
to injure yourself when handling it.
n
An ultra-hardened blade is used for the cutter blade, and
physically, it is extremely brittle material, so care should be
taken not to bump it against any of the metal parts of the printer,
etc. and damage it.
n
When performing service operations on items which are
controlled as after service parts but which no procedures have
been provided for, the state of the parts should be observed
closely before beginning the operation to get a thorough idea of
how to proceed.
n
See the drawing at right concerning directions during repair
operations.
n
If you have to loosen a screw that has blue screw-lock applied to
its head, make sure you apply blue screw-lock again when
reassembling.
