Tips on How to Use Your Machine
This section introduces the tips on how to use your machine and for printing with optimal quality.
Ink is used for various purposes.
How is ink used for various purposes other than printing?
Ink may be used for purposes other than printing. Ink is not only used for printing, but also for cleaning
the Print Head to maintain the optimal printing quality.
The machine has the function to automatically clean the ink jet nozzles to prevent clogging. In the
cleaning procedure, ink is pumped out from the nozzles. Used ink for nozzle cleaning is limited to a
small amount.
Important
The ink pumped out from the nozzles, such as when cleaning the Print Head, is absorbed by ink
absorber in the machine. The ink absorber needs to be replaced when it is full. You cannot replace
it by yourself. When the error message appears, contact your Canon service representative as
soon as possible.

Does black-and-white printing use color ink?
The use of each ink varies depending on the color of image to be printed or the contents of document.
Two kinds of black ink (PGBK and BK) are used automatically depending on the media type to print or on
the settings of the printer driver. PGBK is used mainly for printing text-based documents and BK is used
mainly for printing photos, illustration, etc. Black-and-white printing may also use ink other than black ink.
So, color ink is consumed even when printing in black-and-white.
Ink lamp indicates when ink is running low.
The inside of the ink tank consists of (A) the part where ink is preserved and (B) the sponge with
absorbed ink.
When the ink (A) runs out, the ink lamp flashes slowly to indicate that the ink is running low. Then, when
the ink (B) runs out, the ink lamp flashes fast to indicate that the ink tank needs to be replaced with a new
one.
