Ink consumption detecting method, and ink jet recording apparatus

Abstract

The present method detects an ink consumption condition in an ink cartridge loaded on an ink jet recording apparatus having a recording head for jetting ink drops, using a piezo-electric device mounted on the cartridge. The method detects the ink consumption condition using the piezo-electric device when the recording head is in a non-recording state. A complicated seal structure is not necessary and the ink residue can be detected surely.
