Filed: 2018-06-29
Abstract: To reduce the possibility of unnecessary discontinuation of image recording while reducing the possibility of damage to a head.SOLUTION: An image recorder records an image on a recording medium by performing a recording passage in which a liquid is ejected onto the recording medium from a head while a carriage is moved. During movement of the carriage in the recording passage, the image recorder determines whether a speed indicated by speed data acquired by speed acquisition means is lower than a predetermined threshold or not. If it is determined that the speed indicated by the speed data is lower than the threshold, the image recorder moves the carriage and, at the same time, determines whether to discontinue or continue execution of the recording passage, by referring to the speed data acquired by the speed acquisition means, at a second time during the recording passage after a predetermined time from a first time at which the determination is made.SELECTED DRAWING: Figure 6
