Lithium Batteries (Memory Back-up)
CAUTION
The danger of explosion exists if a battery of this type is incorrectly
replaced. Replace only with the same or an equivalent type
recommended by the manufacturer. Discard used batteries in
accordance with the manufacturer's instructions.
Important:
Before servicing this machine, please read the following notes.
Do not touch the nozzle section in the ink cartridge. This helps prevent
the nozzles from clogging.
Do not touch the wiper blade on the purge unit. This also helps prevent
the nozzles from clogging. (Please refer to section 2.2 for details.)
Do not touch the aluminum plate on the ink cartridge. The aluminum
plate heats up during printing. It becomes quite hot during continuous
high duty printing.
After repairs or maintenance, excessive ink may remain on the contact
section of the cartridge, covers, and TIJ unit. Remove this ink with a dry
cloth. The ink is electrically conductive and it may short an electrical
component.
Always store an extra cartridge (if unpacked) in the cartridge box in-
cluded with the machine.
Ensure that the TIJ unit has completed its cleaning operation before un-
plugging the machine.
Ensure that the carriage is at the head capping position (home position)
before leaving the machine unplugged for long periods.
