Precautions On Handling - Epson TM-C3400Z User Manual

Charging ink for the first time
Initial ink charging starts automatically after installing the roll paper,
turning on the printer, and installing the ink cartridge. Initial charging
will require approximately 8 minutes.
Note:
Do not turn the power off or open the roll paper cover or ink cartridge
cover while the cartridges are being charged with ink.

Precautions on Handling

When the ink cartridge is installed for the first time, the product uses ink
to prepare for printing (ink charging). Ink charging takes approximately
eight minutes.
The ink cartridge contains 3 colors of ink. Even when one particular color
is specified, all 3 colors of ink are used for printing and for keeping the
print head in good condition. When the ink level of even one color
comes to the lowest limit, the product stops printing.
Do not touch the IC chip on the cartridge. Doing so may cause
operating/printing malfunction.
This product uses ink cartridges equipped with an IC chip that monitors
the amount of ink used by each cartridge. Cartridges are usable even if
they are removed and reinstalled. However, if an ink cartridge in which
little amount of ink remains is removed and reinstalled, it may not be
usable. Some ink is consumed each time cartridges are installed
because the product automatically checks their reliability.
Since ink cartridges are designed to stop the operation before ink runs
out completely to maintain the quality of the print head, some ink
remains in the used ink cartridge.
All the ink colors are consumed also for the maintenance operations
when an ink cartridge is replaced and for print head cleaning.
Do not turn off the product or open the ink cartridge cover while
charging ink (Power light is flashing). Opening the cover may cause the
ink to be recharged, resulting in more ink being consumed. Also, it may
cause printing malfunction.
Even for monochrome printing, all the ink colors are used in an
operation designed to maintain the printing and print head quality.
Do not disassemble the ink cartridge. Doing so may cause ink to adhere
eyes and skin.
Do not disassemble and remodel the ink cartridge. Doing so may cause
printing malfunction.
Use of an old ink cartridge may result in reduced print quality. Use it up
within six months after opening the package. The usage period for ink
cartridges is printed on the packaging of individual ink cartridges.
