Abstract
A control unit causes a carriage to move in a width direction under a first movement control of changing a location of the carriage with a first resolution so that a sensor located forward in movement detects an edge of a medium. Thereafter, the first movement control is switched to a second movement control of changing the location of the carriage with a second resolution higher than the first resolution and the carriage is caused to move in the width direction so that a sensor located rearward in movement detects the edge.
Claims14
A printing device comprising:
- a transport mechanism that transports a medium;
- a print head that performs printing on the medium;
- a carriage that moves in a width direction intersecting a transport direction of the medium by the transport mechanism;
- two sensors mounted on the carriage and disposed at different locations in the width direction;
- and
- a controller that controls at least movement of the carriage, wherein
- the controller
- is switchable between a first movement control of changing a location of the carriage with a first resolution and a second movement control of changing a location of the carriage with a second resolution higher than the first resolution, and
- causes the carriage to move in the width direction under the first movement control so that a first edge of the medium is detected by one of the two sensors located forward in movement, and then switches from the first movement control to the second movement control and causes the carriage to move in the width direction so that the first edge of the medium is detected by one of the two sensors located rearward in movement.
A printing device controlling method for controlling a printing device including
- a transport mechanism that transports a medium,
- a print head that performs printing on the medium,
- a carriage that moves in a width direction intersecting a transport direction of the medium by the transport mechanism, and
- two sensors mounted on the carriage and disposed at different locations in the width direction, the printing device controlling method comprising:
- causing the carriage to move in the width direction under a first movement control of changing a location of the carriage with a first resolution so that one of the two sensors located forward in movement detects a first edge of the medium;
- then
- switching from the first movement control to a second movement control of changing a location of the carriage with a second resolution higher than the first resolution;
- and then
- moving the carriage in the width direction so that the first edge of the medium is detected by one of the two sensors located rearward in movement.
