 Supplement: Regarding remaining ink amount
When the Ink Counter detects ink out, a certain amount (safety margin) of ink is still remaining in the
cartridge to prevent the printhead from damages caused by printing without ink. This safety margin is
important especially for a printer that discharges larger amount of ink.
The figure below illustrates the concept of this safety margin.
