Abstract: A replacement assisting liquid having a lower specific weight than an ink is introduced into a recording head filled with a preservative solution containing at least a moisturizing agent to discharge the preservative solution out of the recording head. Next, the ink is introduced into the recording head to discharge the replacement assisting liquid out of the recording head.

Abstract: An image forming apparatus includes a recording head, a controller, and a correction processor. The controller determines a nozzle corresponding to an image to be printed, and causes the recording head to eject ink from the nozzle. The correction processor detects an abnormally ejecting nozzle out of the nozzles in the recording head, and designates the abnormally ejecting nozzle as a target nozzle, and performs correction processing based on a status of the target nozzle, to the image. The correction processor also adds the detected abnormally ejecting nozzle to history data, each time a detecting operation is performed, and selects a nozzle included in the history data as an additional target nozzle, out of the nozzles that have not been detected as the abnormally ejecting nozzle, through the current detecting operation, and adds the selected nozzle to the target nozzle.

Abstract: An inkjet recording apparatus includes a sheet conveying unit, a storage unit, a line head, and a control unit. The line head includes an upstream-side head and a downstream-side head. The upstream-side and downstream-side heads are fitted to have overlapping portions in which a plurality of nozzles arranged in respective end portions of the heads overlap as seen from the sub scanning direction. When an adjustment chart is printed, the control unit makes the nozzles in the overlapping portion of the upstream-side head print a first line. The control unit makes the nozzles in the overlapping portion of the downstream-side head print a second line.
