US 11,590,765 B2 · Image forming device and image formation method

Abstract

An ink jet printer includes a transporting section configured to transport continuous paper in a transport direction, an ink jet head forming a nozzle array having a plurality of nozzles aligned in the transport direction, a cutting section configured to cut the continuous paper in an intersecting direction, and a controller configured to control the transporting section, the ink jet head, and the cutting section. The controller causes the ink jet head to form, on the continuous paper, a first image and a second image that are adjacent to one another in the transport direction, causes a nozzle among the nozzles aligned in the nozzle array to form a test pattern in a region between the first image and the second image, and causes the cutting section to cut the continuous paper to separate, from the continuous paper, the inter-image region in which the test pattern was formed.

Dependent claims

An image forming device comprising:

a transport roller configured to transport continuous paper in a first direction;
an ink jet head including a nozzle array having a plurality of nozzles aligned in the first direction;
a cutter configured to cut the continuous paper in a second direction intersecting the first direction;
and
a controller configured to control the transport roller, the ink jet head, and the cutter, wherein
the controller causes the ink jet head to form, on the continuous paper, a first image and a second image that are adjacent to one another in the first direction, causes a nozzle among the nozzles included in the nozzle array to form a test pattern in a region between the first image and the second image, and causes the cutter to cut the continuous paper to separate, from the continuous paper, the region in which the test pattern was formed, and
the region has a shorter length in the first direction than a length of the nozzle array in the first direction.

An image formation method comprising:

transporting continuous paper in a first direction;
forming a first image on the continuous paper by an ink jet head including a nozzle array having a plurality of nozzles aligned in the first direction;
forming a test pattern by a nozzle among the nozzles included in the nozzle array, the test pattern being upstream with respect to the first image in the first direction;
forming a second image by the ink jet head, the second image being upstream with respect to the test pattern in the first direction;
and
separating a region in which the test pattern was formed and that is between the first image and the second image from a first printed matter with the first image printed thereon and a second printed matter with the second image printed thereon by cutting the continuous paper in a second direction intersecting the first direction,
wherein the region in which the test pattern was formed has a shorter length in the first direction than a length of the nozzle array in the first direction.
