• Wear gloves while performing disassembly/
W A R N I N G
reassembly to prevent accidental cuts.
• If ink contacts the eyes, rinse eyes with clean water
and consult a physician.
• If ink contacts the skin, wash with soap and water.
Consult a physician if the skin becomes inflamed.
• A lithium battery is installed on the MAIN Board.
Prevent damage by following the cautions below when
handling the MAIN board.
Avoid putting the MAIN board on conductive
surface while the battery is installed.
When the battery is removed, be sure not to mistake
the polarity when reinstalling it.
Ensure adequate work space for performing service/
C A U T I O N
maintenance.
The printer should be placed on a stable surface.
Use care in handling the printer, since it is unusually
heavy (approx. 40kg).
Perform ink discharge before removing/replacing parts
of the ink routing system.
Refer to "5.1.5 Adjustment Item (p371)".
Carefully install/connect ink routing system parts when
reassembling after disassembly. (To prevent ink leaks
due to faulty installation/connection.)
Use only recommended tools for disassembly,
reassembly and adjustment.
Use only specified lubricants and adhesives when
applying lubrication or adhesive.
Place a protective sheet on the floor before removing ink
routing parts because there is the possibility that leaking
ink could get onto the product or floor where the product
is set up.
Disassembly & Assembly
To prevent static electric damage when handling a
C A U T I O N
circuit board, do not touch elements on board with bare
hands. If handling with bare hands is unavoidable,
perform work by using required measures, such as
wearing a grounding strap.
Carefully confirm the connection ends/directions of
electric part connectors when reassembling after
disassembly. This printer uses several FFC (flexible flat
cable), so use care in properly connecting connectors to
prevent misalignment or other connection problems that
can damage PCB elements by short circuits.
Route cables of electric components along specified
locations when reassembling after disassembly.
(Routing cables by other locations may push the cables
against sharp edges or reduce noise resistance margins.
When allowing the printer to operate with covers
removed, be careful not to get hands or clothing caught
in moving parts.
Use care to avoid injury when handling the cutter blade
because it is very sharp.
The cutter uses a very hard blade that is unusually
brittle, so do not allow it to be damaged by bumping into
objects such as metal printer parts.
When it is necessary to disassemble units or parts that
do not have written procedures because they are
controlled as service parts, carefully note installed
conditions before starting disassembly.
When loosening screws on the outside of the printer that
have blue locking seal applied to them, apply new
locking seal to the screws when reassembling.
When removing units or parts that are secured with
acetate (black) or two-sided tape, always secure the
units or parts with those tapes when reassembling.
