  • Publication number: 20230202178
    Abstract: A maintenance operation can be executed by ejecting a liquid when a time measured with reference to displacement of a cap from a maintenance position to a separation position exceeds a defined time. Before start of a recording operation in a recording job, a first medium waits at a standby position where the medium can wait upstream of a liquid ejection head. The cap is located at the separation position when a first medium in the recording job is waiting at the standby position. During an initial control period, in parallel with the maintenance operation, a post-processing operation can be executed on a second number of media that is smaller than a first number of media, and a post-processing operation can be executed on the first number of media in parallel with the maintenance operation after end of the initial control period.
