INKJET RECORDING APPARATUS
First Claim
1. An inkjet recording apparatus comprising:
- a plurality of line heads disposed along a conveyance direction of a recording sheet and including a plurality of nozzles to discharge ink droplets, the plurality of nozzles disposed in a direction perpendicular to the conveyance direction of the recording sheet;
a plurality of edge sensors corresponding to respective line heads of the plurality of line heads, to detect a lateral edge of the recording sheet;
a plurality of actuators corresponding to the respective line heads, to move to the respective line heads laterally in a sheet width direction;
a head position adjustor to determine movement amounts of the respective line heads in accordance with outputs of the plurality of edge sensors; and
a failure determiner to obtain outputs of the plurality of edge sensors simultaneously and identify a failure of the plurality of edge sensors based on a combination of the outputs from the plurality of edge sensors.
