Image recording apparatus

An image recording apparatus, comprising:

• a conveyer configured to convey a sheet-formed medium in a conveying direction, the conveyer including a pair of conveyer rollers, the pair of conveyer rollers being configured to nip a sheet-formed medium and rotate with the sheet-formed medium nipped there-between;
• a recorder located at a position downstream from the pair of conveyer rollers in the conveying direction, the recorder being configured to record an image on the sheet-formed medium;
• a first sensor located at a position upstream from the pair of conveyer rollers in the conveying direction, the first sensor being configured to detect the sheet-formed medium conveyed by the conveyer;
• a second sensor positioned upstream from the first sensor in the conveying direction by a first distance, the second sensor being configured to detect the sheet-formed medium;
• and
• a controller configured to:
• control the conveyer to convey the sheet-formed medium by a first conveyance amount, the first conveyance amount being greater than a second distance between a detecting position where the first sensor detects the sheet-formed medium and a nipping position where the sheet-formed medium is nipped by the pair of conveyer rollers, the first conveyance amount further being smaller than the first distance,
• control the recorder to record a part of the image on the sheet-formed medium having been conveyed by the first conveyance amount,
• after the part of the image is recorded on the sheet-formed medium, within a period between a point before the first sensor detects an upstream end of the sheet-formed medium in the conveying direction and a point after the first sensor detects the upstream end of the sheet-formed medium, control the conveyer to convey the sheet-formed medium by a second conveyance amount in a plurality of segmented actions, the second conveyance amount in each of the plurality of segmented actions being smaller than the second distance,
• correct a conveyance amount to convey the sheet-formed medium after the first sensor detects the upstream end of the sheet-formed medium to a third conveyance amount, the third conveyance amount being smaller than the conveyance amount, and
• after the sheet-formed medium is conveyed by the third conveyance amount, control the recorder to record another part of the image on the sheet-formed medium,
• wherein a distance of separation between the detecting position where the first sensor detects the sheet-formed medium and another detecting position where the second sensor detects the sheet-formed medium along the conveying direction is greater than a distance corresponding to the first conveyance amount.
