Patent ID: 7306309

Claim:
A liquid discharge apparatus having a head with a plurality of liquid dischargers and nozzles with a respective one of the plurality of nozzles operably associated a respective one of the liquid dischargers, the plurality of liquid dischargers and nozzles being aligned in a row, each one of the plurality of liquid dischargers defining an ink chamber, the liquid discharge apparatus, comprising: a main controlling unit formed on each liquid discharger, the main controlling unit controlling the discharge of droplets from the nozzles; a secondary controlling unit formed on each liquid discharger, the secondary controlling unit controlling the discharge of a droplet so that the droplet is discharged along at least one secondary direction different from a main direction of the droplets discharged by said each liquid discharger controlled by the main controlling unit; a secondary-control executing unit for individually setting whether or not the secondary controlling unit for each liquid discharger is operated; and a plurality of heat-generating resistor assemblies, each heat-generating resistor assembly including a pair of heat-generating resistors, a respective one of the plurality of heat-generating resistor assemblies being disposed in a respective chamber, wherein the main controlling unit is operative to individually control an amount of heat of the heat-generating resistors of each one of the plurality of heat-generating resistor assemblies, the amount of heat generated in one heat-generating resistor of at least one pair of the heat-generating resistors being different than a remaining one of the at least one pair of the heat-generating resistors.
