  • Patent number: 4926191
    Abstract: A controller of an image recording apparatus controls an initializing process for adjusting and appropriately positioning tip ends of the set recording sheets by transporting the recording sheets in a reverse direction until tip ends thereof are detected.

This recording sheet is then transported in a reverse direction until a cut end of this recording sheet reaches a first predetermined position. After the tip end of the other recording sheet is detected this recording sheet is transported in the forward direction until the tip end thereof reaches a position on the downstream side of the cutter, and a tip portion of this recording sheet is cut by the cutter.
