US Patent 11981140 Ink-jet recording apparatus

When printing is performed on a recording medium of a second size larger than a first size, a control portion, after passage of the recording medium of the first size at a position opposite a recording head before arrival of the recording medium of the second size at the position opposite the recording head, makes the recording head perform preparatory flushing processing in which ink is ejected toward openings from first nozzles that have not been set as target nozzles during printing on the recording medium of the first size but will be newly set as the target nozzles during printing on the recording medium of the second size.
