the print head assembly.

The above figures are based upon the following
assumptions:
• Continuous printing at a resolution of 600 x 600
dpi in normal mode after installing new ink
cartridge;
• The printing frequency;
• The number of pages printed;
• Periodic, automatic, print head assembly cleaning
(Your machine will clean the print head assembly
periodically. This process will use a small amount
of ink); and,
• Ink remaining in cartridge identified as “empty” (It
is necessary to leave a small amount of ink in the
ink cartridge to prevent air from drying out and
damaging the print head assembly).
