  • Patent number: 7992957
    Abstract: A method of inspecting a discharge state of a nozzle prevents wrongly determining that discharge is normal even though fluid droplets are not discharged normally. In a fluid droplet discharge device such as an inkjet printer, a momentary induced current is produced when a charged ink droplet 17c lands on a head cap 31 with a potential difference. A voltage change detection unit 39 detects the induced current as a voltage change. A decision unit 40 determines that the ink discharge state is normal if the maximum amplitude L of the voltage change detected by the voltage change detection unit 39 in a first period S is greater than or equal to a first threshold value Q. If the amplitude of voltage change detected in a third period U after the specific period has passed goes to a second threshold value R, a decision cancellation unit 41 determines that noise is contained in the voltage change.

  • Patent number: 7992960
    Abstract: One or more preventative maintenance mode parameters for an inkjet-printing device having an inkjet-printing mechanism are determined based on a water loss rate of water from ink within the device and/or on an air gain rate of air into the ink within the device. As such, periodic performance of a non-user-initiated preventative maintenance mode based on the preventative maintenance mode parameters results in the ink within the inkjet-printing mechanism being sufficiently fresh so as not to affect quality of image formation by the inkjet-printing device. Therefore, the non-user-initiated preventative maintenance mode for the inkjet-printing device is periodically performed based on the preventative maintenance mode parameters to eject at least some of the ink from, and to refill fresh ink into, the inkjet-printing mechanism.
