Abstract: Even when ejection characteristics of ink droplets are dispersed between unit heads and when arrangement accuracies of unit heads are dispersed, stripe unevenness is alleviated by correction corresponding to each unit head. In a liquid ejection apparatus having a line head (10) arranged by juxtaposing a plurality of (unit) heads (11) of liquid ejection parts so as to connect the head (11) to the adjacent head (11), the liquid ejection apparatus includes ejection direction changing means for enabling the ejection direction of liquid droplets ejected from a nozzle of each liquid ejection part to change in a plurality of directions in the arranging direction of liquid ejection parts and reference direction setting means for individually setting one reference principal direction for each head (11) among a plurality of ejection directions of liquid droplets by the ejection direction changing means. In the (N−1)th and the (N+1)th head 11, the third ejection direction from the left is established as the principal direction while in the Nth head 11, the second ejection direction from the right is established as the principal direction.

Abstract: A liquid-amount detecting apparatus detects the amount of a liquid in containers. The liquid-amount detecting apparatus includes a liquid detecting circuit and a determining unit. The liquid detecting circuit includes electrode units disposed so as to be in contact with the liquid in the containers, which becomes electrically conductive when in contact with the liquid, an impedance, and an AC-signal source. An AC signal not containing a DC component is input from the AC-signal source to the electrode units through the source impedance, and a signal representing the status of electric connection of the electrode units is output. Furthermore, based on the output signal, a binary signal representing the presence or absence of electrical connection of the electrode units is output. The determining unit determines the presence or absence of the liquid at the electrode units based on the binary signal output from the liquid detecting circuit.

Abstract: The liquid discharge apparatus includes a head having liquid dischargers capable of deflecting the trajectories of discharged droplets in a plurality of directions. At least two of the liquid dischargers neighboring each other are capable of discharging droplets in the same pixel area. When there is a shut-off liquid discharge due to droplet discharge failure, this information is stored. According to the stored information, the discharge signal corresponding to the droplets the shut-off discharger were supposed to discharge is transferred to another liquid discharger in the vicinity of the shut-off discharger. This other liquid discharger alternatively discharges droplets so that the droplets land in a position the droplets would have had landed if they were discharged by the shut-off discharger.
