Caution:
Never turn off the RX580 while ink is charging or you'll waste ink.
Note:
You cannot continue printing or copying with one ink cartridge expended, even if
the other cartridges still contain ink. Before printing, replace the expended
cartridge.
The RX580 uses ink cartridges equipped with IC chips that monitor the amount of
ink used by each cartridge. Cartridges are usable even if they are removed and
reinserted. Some ink is consumed each time cartridges are inserted, however,
because the printer automatically checks their reliability.
If you remove a cartridge that is low (for which you have received an "Ink low"
message), and you temporarily install a new cartridge in its place, you cannot reuse
the low cartridge.
Ink is consumed during the following operations: print head cleaning, self-cleaning
(when the printer is turned on), and ink charging (when an ink cartridge is installed).
