Abstract: A method of printing a test pattern in a printer includes printing a related-information acquisition pattern as the test pattern in a particular state by driving a plurality of drive elements of a liquid ejection head to eject a liquid droplet from a plurality of nozzles based on a temperature detected by a temperature sensor. The related-information acquisition pattern is a pattern for acquiring related information relating to at least one of an ejection amount and a liquid droplet landing position of the liquid droplet ejected from each of the plurality of nozzles. The liquid droplet landing position is a position at which the liquid droplet ejected from each of the plurality of nozzles lands on a recording medium. The particular state is a state where a temperature difference between the temperature detected by the temperature sensor and an actual temperature of the liquid ejection head is constant.

Abstract: An image recording apparatus includes first and second conveying passages, a recording portion for recording images, first and second conveying rollers, first and second motors, a power transmission mechanism switchable between a first state and a second state, and a controller. In the first state of the mechanism, the controller drives the first motor to rotate the first and second conveying rollers, thereby conveying a recording medium along the first conveying passage in a first conveying direction. During this conveyance, the controller controls the recording portion to record an image on one surface of the recording medium. Then, the controller switches the mechanism from the first state to the second state, and drives the second motor in the second state of the mechanism to rotate the second conveying roller independently of the first conveying roller, thereby conveying the recording medium along the second conveying passage in a second conveying direction.

Abstract: There is provided a printer including: a conveyance unit; a liquid jetting head including at least one nozzle array in which nozzles are arrayed; a carriage; a guide; a carriage moving unit; a memory; and a controller. The controller performs printing by performing scan printing operation and a conveyance operation multiple times repeatedly and adjusts jetting timings of the liquid jetted from the nozzles at positions in a scanning direction based on pieces of inclination information corresponding to the respective positions. In second or subsequent scan printing operation of the multiple times of scan printing operation, the controller delays or advances, based on the inclination information, the jetting timing in the second or subsequent scan printing operation relative to the jetting timing in scan printing operation immediately before the second or subsequent scan printing operation more greatly, as inclination of the at least one nozzle array increases.
