Recording apparatus and method for suppressing deviation of recording position of recording apparatus

A method for suppressing a deviation of a recording position in a recording apparatus, in which the recording apparatus includes a medium mounting section that includes a mounting section body that is configured to mount a medium and a pair of edge guides that guides the medium mounted on the mounting section body to be positioned in a width direction, a transport section that transports the medium mounted on the medium mounting section along a transport passage, and a recording head that performs recording on the medium, and suppresses a deviation in the width direction between the transported medium and the recording position to the medium, the method comprising:

• transporting the medium mounted on the medium mounting section;
• detecting at least one of both side edges of the medium transported from the medium mounting section in the width direction intersecting the transport passage;
• acquiring a deviation amount of the medium in the width direction to the recording head based on a detection position of at least one of the detected side edges;
• and
• adjusting an assembly position of the edge guide to the mounting section body in the width direction according to the deviation amount.

A recording apparatus comprising:

• a medium mounting section that is configured to mount a medium;
• a transport section that transports the medium mounted on the medium mounting section;
• a recording head that performs recording on the medium;
• a medium detection section that detects at least one of both side edges of the medium transported from the medium mounting section in a width direction intersecting a transport direction of the medium;
• and
• a deviation amount acquisition section that acquires a deviation amount of the recording head in the width direction of the medium based on at least one side edge detection position detected by the medium detection section, wherein
• the medium detection section includes a sensor that is movable in the width direction at a position upstream in the transport direction from a nozzle of the recording head, and
• when the medium detection section performs a detection operation, the deviation amount acquisition section sets a position when the sensor is switched from a non-detection state to a detection state as a detection position of one side edge, and after a first integrated value, which is obtained by integrating the number of detection by the sensor from the detection position for each unit position, exceeds a threshold value set in advance according to a medium size, the medium detection section sets a position when the sensor is switched from the detection state to the non-detection state as a detection position of the other side edge.
