Image recording device, method of controlling image recording device, and non-transitory computer-readable recording medium therefor

A method of controlling an image recording device provided with a conveyance mechanism configured to convey a recording medium in a conveyance direction, a head configured to print an image onto the recording medium, a moving mechanism configured to move the head with respect to the conveyance mechanism in an orthogonal direction orthogonal to the conveyance direction, and a sensor configured to detect a position of an orthogonal edge of the recording medium being conveyed by the conveyance mechanism, the orthogonal edge being an edge of the recording medium in a direction orthogonal to the conveyance direction, the method comprising:

• deriving a correction amount for a printing position of the head in the orthogonal direction based on position of the orthogonal edge detected by the sensor;
• correcting the printing position of the head by driving the moving mechanism to move the head based on the correction amount;
• and
• causing the head to print an image based on image data at the corrected printing position.

A non-transitory computer-readable recording medium for an image recording device provided with a conveyance mechanism configured to convey an image recording medium in a conveyance direction, a head configured to print an image onto the image recording medium, a moving mechanism configured to move the head with respect to the conveyance mechanism in an orthogonal direction orthogonal to the conveyance direction, a sensor configured to detect an orthogonal edge position of the image recording medium being conveyed by the conveyance mechanism, the orthogonal edge position being an edge of the image recording medium in a direction orthogonal to the conveyance direction, and a controller, the non-transitory computer-readable recording medium storing computer-executable instructions which cause, when executed by the controller, the image recording device to perform:

• deriving a correction amount for a printing position of the head in the orthogonal direction based on the orthogonal edge position detected by the sensor;
• correcting the printing position of the head by driving the moving mechanism to move the head based on the correction amount;
• and
• causing the head to print an image based on image data at the corrected printing position.
