Ink Cartridge Status While Printing
Low The Low message is an early warning sign and it is advisable that
new supplies should be obtained of that particular color. The
amount of ink remaining in the Ink Cartridge depends on it’s
capacity:
n Approx. 43.8 ml remaining in a 175 ml Ink Cartridge.
n Approx. 63.8 ml remaining in a 350 ml Ink Cartridge.
To check how much ink is remaining, refer to page 3-8, Obtaining
Ink Cartridge Information.
Very Low When the Very Low message is displayed, overnight printing
should not be attempted. Changing the Ink Cartridge is strongly
recommended to prevent the printer from stopping halfway through
a print. The amount of ink remaining in the Ink Cartridge will be
approx. 25 ml.
To check how much ink is remaining, refer to page 3-8, Obtaining

Empty The printer will stop and will not be able to continue printing until a
new ink cartridge has been installed. If this occurs halfway through
printing an image, you should check the quality of this image, as
stopping mid-plot can affect the print.
