Abstract
A system for detecting an ink consumption in an ink jet recording device comprises a non-volatile memory for storing an accumulated amount of ink consumption, update section for incrementing the stored amount by a new amount of ink consumption, a comparator for comparing the accumulated amount against a variable reference amount, and a display section for displaying the accumulated amount of ink consumption or a residual amount of ink in the ink jet recording device. The recorded amount includes total ink consumption by nozzle cleaning, nozzle suction and ink discharge.
