When should I Replace an Ink System?
You should replace an ink system when prompted by the printer. When the printer
runs out of one or more colors of ink, the printer displays the following message on
the front panel.
The printer displays four blocks representing the four ink colors with empty ink
systems shown as blinking empty blocks. The printer displays the colors in the
same positions as installed in the printer.
The “Out of ink” message will be displayed for the following reasons:
n The printhead check detects too many non-working nozzles in the printhead and
at the same time it is low on ink.
n The printer stops printing due to an abnormal increase in the temperature of the
printhead (normally because there is no ink), and at the same time it is low on
ink.
n The ink level monitor estimates that the ink system has used so much ink that it
is beyond all possible ink-consumption tolerances.
NOTE It is recommended that you set the printhead check frequency to 1 (see page 9-
6, Checking Printheads) if you see any of the printheads low on ink and you plan
to leave the printing working unattended. By doing this you can limit the
number of prints wasted due to printheads out of ink.
