„
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 fans.
„
The cutter blade is razor-sharp. Be especially careful when
handling the cutter.
„
Carbide blade employed for the cutter blade is hard but brittle.
Be careful not to hit it against metal parts of the printer as it
can be easily damaged.

Be careful not to mistakenly reset the life counters for the parts or
components which are not replaced or checked. Especially, the
waste ink counter “MAIN TANK” in the Adjustment Program
should NOT be reset. Doing so adversely affects the printer
operation and may result in ink leakage.
