Publication number: 20240286410Abstract: An image recording apparatus includes a head having nozzles, an expelling device, a discharge-testing device to output condition signals according to discharging conditions of the nozzles, a storage to store information concerning the condition signals, and a controller. In response to receipt of a record command, the controller controls the expelling device to expel a liquid from the nozzles based on the information concerning the condition signals stored in the storage, and thereafter, controls the head to discharge the liquid for recording an image on a recording medium. In response to receipt of a particular signal indicating a potential for receiving the record command, the controller executes a discharging-test process in which the controller controls the discharge-testing device to output the condition signals according to the discharging conditions of the nozzles and a storing process in which the information concerning the condition signals is stored in the storage.Type: ApplicationFiled: February 26, 2024Publication date: August 29, 2024Inventors: Misaki HARUHARA, Nobumasa TANAKA, Ryuji HORATA, Takafumi NAKASE, Isao KUBO, Masahiro HAYASHI, Zenichiro SASAKI
