1.5.1

Ink Out

When the printer runs out the most part of the ink of any one color, it warns ink-low and keeps printing.
When the printer runs out the whole ink of any one color, it stops printing and indicates ink-out error.
User is requested to install a new ink-cartridge in this state. An ink-cartridge once taken out should never
be used again. Re-installation of the cartridge not filled fully upsets the ink level detection and may
cause a serious problem in the print head as a result.


Never use the ink cartridge once taken out from the printer.
Following explains the reason of the above warning.


After the cartridge is once taken out, airs come in from the ink supply hole located at the top of
cartridge and becomes bubbles, and they are absorbed into the head during printing performance.
Therefore, the head will be unable to discharge the ink properly. Also, inevitable entering of bubbles
when installing a new ink cartridge can be absorbed to ink itself since the ink itself in the cartridge is
deaerated during the production process. However, this absorbing ability can last only about one hour
after the cartridge is installed.


Even after the bubble absorbing ability described above stops, there is no worry about entering
bubbles as long as the ink cartridge is being installed to the printer. However, if the ink cartridge
which does not have absorbing ability any more is once removed from the printer, new coming
bubbles into the cartridge will never disappear naturally. These bubbles may cause not only printing
malfunction but also thickening ink. This thickened ink goes into the head and clogs ink path in the
head or nozzle and may cause serious head damage.


As standard specification for EPSON Stylus Color 600, ink consumption counter is reset when the ink
cartridge is removed. If an ink cartridge is removed and re-installed unnecessarily the value on the
ink consumption monitor which the user can check will be wrong and
even though the ink cartridge is installed empty. This may cause head damage.
