There are two circumstances under which
you may need to replace an Ink Cartridge:
The Printer has detected that the Ink Cartridge is empty or faulty.
You decide to replace the Ink Cartridge.
If the printer detects that an Ink Cartridge needs replacing, you
will see the message:
with six icons (explained below), referring from left to right
to the Cyan (•), Black (•),
Magenta (•) and Yellow (•)
Ink Cartridges.
The icons may be any of the following:
The Ink Cartridge is OK;
the approximate level of the ink is indicated - a full cartridge has
the whole interior black;
Flashing; the Ink Cartridge is missing,
and the correct one must be inserted;
Flashing exclamation mark; the Ink Cartridge
is low on ink, and needs replacing at the earliest
opportunity; For some types of Prints (like line drawings) the Ink
Cartridge may still last much longer.
Flashing pump; the Ink Cartridge is out
of ink, and must be replaced before any further printing
can be done;
Flashing cross; the wrong Ink Cartridge
is installed, and must be replaced before any further printing can
be done.
Sand Clock; the Ink Cartridge will expire
in X amount of days. The X is displayed at the top of the screen.
