摘要： A density-adjusting method of a liquid-discharging apparatus having a head including a plurality of juxtaposed liquid-discharging units having respective nozzles, forming dots by landing droplets discharged from the nozzles onto a droplet-landing object, and providing half tones by arranging a dot array is provided. A density-measuring pattern including all pixel trains lying in the main scanning direction with a constant density is formed, the density of the pattern is scanned so as to obtain density information and the relationship between the number and the density of droplets with respect to each pixel train. Upon receipt of a discharge command signal, based on the obtained data with respect to each pixel train, the density of the pixel train corresponding to the discharge command signal is adjusted by making the number of droplets to be actually discharged from the nozzles different from that of droplets discharged according to the discharge command signal.

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.

摘要： The liquid discharge apparatus including 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.
