Patent ID: 7354130

Claim:
An inkjet recording apparatus, comprising: a recording head including a plurality of nozzles which are aligned in a sub-scanning direction, wherein the recording head includes a mark printing nozzle which records a mark on a recording medium; a recording head moving section to move the recording head in a main scanning direction which is perpendicular to the sub-scanning direction; a mark detecting unit, which is mounted at a position separated from the mark printing nozzle along the sub-scanning direction, to detect the mark; a recording medium feeding section to feed the recording medium in the sub-scanning direction; a control section which controls the mark printing nozzle to print the mark on the recording medium and controls the recording medium feeding section to feed the recording medium for a predetermined distance, by controlling the recording medium feeding section to feed the recording medium until the mark detecting unit detects the mark and then to feed the recording medium for a distance based on the predetermined distance; a feeding distance detecting section which detects a feeding distance by which the recording medium is fed by the recording medium feeding section; and a memory section to store the feeding distance detected by the feeding distance detecting section; wherein said distance based on the predetermined distance is a difference between the predetermined distance and a feeding distance by which the recording medium is fed until the mark is detected; and wherein when the mark detecting unit detects the mark, the control section resets the feeding distance stored in the memory section, and controls the recording medium feeding section to feed the recording medium in the sub-scanning direction until the feeding distance detected by the feeding distance detecting section matches said distance based on the predetermined distance.
