ABSTRACT:
The amount of ink ejected from a recording head is measured using a quartz crystal microbalance (QCM) method. An ink detector arranged outside an image area includes an AT-cut quartz oscillator constructed by vapor-depositing Al electrodes on both surfaces of a quartz plate, and the ink ejected from the recording head mounted on a carriage is deposited on this quartz oscillator. A change in resonant frequency caused in the quartz oscillator due to the deposition of the ink is detected, and the mass of the ink ejected from the recording head is measured based on the detection results.
