❏
You cannot use the ink supply units that came with the printer for the replacement.
❏
If the ink supply unit has changed shape due to being dropped and so on, fix the shape before inserting it in the
printer; otherwise, it may not be set correctly.
Consumption of ink
❏
To maintain optimum print head performance, some ink is consumed from all ink supply units during
maintenance operations such as print head cleaning. Ink may also be consumed when you turn on the printer.
❏
When printing in monochrome or grayscale, color inks instead of black ink may be used depending on the
paper type or print quality settings. This is because a mixture of color inks is used to create black.
❏
The ink in the ink supply units supplied with your printer is partly used during initial setup. In order to produce
high quality printouts, the print head in your printer will be fully charged with ink. This one-off process
consumes a quantity of ink and therefore these ink supply units may print fewer pages compared to subsequent
ink supply units.
❏
Quoted yields may vary depending on the images that you are printing, the paper type that you are using, the
frequency of your prints and environmental conditions such as temperature.
❏
For best results, use up ink supply unit within two years of installation.
