Apparatus and method for controlling recording and sheet conveying based on recording scans and sheet position

A method for controlling a recording apparatus for forming images using a recording head scanning over a predetermined area on a sheet N times, the recording apparatus including a feeding roller configured to convey the sheet disposed on a stacking unit and a conveying roller configured to further convey the sheet fed by the feeding roller, the method comprising:

• controlling drive of the conveying roller each time scanning is performed by the recording head;
• and
• controlling a first recording in which the scanning is performed N times by selecting recording elements of the recording head until a trailing end of the sheet reaches a predetermined position defined between the feeding roller and the conveying roller, and controlling a second recording in which the scanning is performed N times using a part of the recording elements of the recording head after the trailing end of the sheet reaches the predetermined position,
• wherein the drive of the conveying roller is controlled so as to perform a conveying operation a number of times based on the value of N after the trailing end of the sheet reaches the predetermined position such that the trailing end of the sheet is disposed in a first range including the position of the conveying roller and upstream of the conveying roller in a direction in which the sheet is conveyed after the conveying operations, and
• wherein at least one of the conveying operations performed a number of times based on the value of N is performed based on a distance from a position of the trailing end of the sheet to the position of the conveying roller.

A recording apparatus comprising:

• a recording head configured to record an image on a sheet;
• a conveying roller, disposed upstream of the recording head in a conveying direction, configured to convey the sheet;
• a pinch roller configured to pinch the sheet, together with the conveying roller, at a nip portion;
• a driving unit configured to drive the conveying roller by a first conveying amount, and by a second conveying amount when the trailing end of the sheet passes through the nip portion;
• and
• an adjustment conveying unit configured to convey the sheet by an adjustment conveying amount, based on information on a position of a trailing end of the sheet such that the trailing end of the sheet stops in a predetermined area located upstream of the nip portion.
