Abstract: A cleaning device includes a cleaning unit, a movement mechanism, and a positioning portion. The cleaning unit includes a cleaning part that has a contact surface extending along an axial direction of a conveyance roller and cleans the conveyance roller, and a cleaning housing that supports the cleaning part. The movement mechanism moves the cleaning unit between a cleaning position and a mounting and removing position. The movement mechanism allows the cleaning part to be brought into contact with the conveyance roller at the cleaning position, allows the cleaning part to be disposed below the conveyance roller in a separated manner at the mounting and removing position and allows the cleaning unit to be mounted on or removed from the apparatus body. The positioning portion restricts a relative position between the cleaning part and the conveyance roller by being brought into contact with the cleaning unit.

Abstract: A cleaning device includes a controller configured to control cleaning of a conveyance roller by a web. The controller includes a take-up control unit and a web end determination unit. The take-up control unit controls the solenoid such that the web is taken up by rotatably driving the take-up roller in a state where the web is pressed to the conveyance roller. The web end determination unit determines whether or not an end of the web is exposed on a support roller by a take-up operation of the take-up roller. The web end determination unit determines that the end of the web is exposed on the support roller when a detection result of a detection unit is not changed in spite of a fact that supplying of electricity to the solenoid is performed.

Abstract: An image forming apparatus includes a recording head, a control unit, and a correction processing unit. The recording head is configured to eject ink corresponding to an image to be printed, using arranged nozzles. The control unit is configured to determine nozzles corresponding to the image to be printed, correspondingly to a position of a print sheet, and cause the recording head to eject ink from the nozzles. The correction processing unit is configured to detect an ejection malfunction nozzle and perform a correction process corresponding to the ejection malfunction nozzles. Further, if the number of the detected ejection malfunction nozzles exceeds a predetermined upperlimit value, the correction processing unit preferentially sets as a target of the correction process an ejection malfunction nozzle that ejects an ink droplet earlier than nozzles corresponding to two adjacent dots of a dot corresponding to the ejection malfunction nozzle.

A control unit is configured to determine nozzles corresponding to the image to be printed, correspondingly to a position of a print sheet, and cause the recording head to eject ink from the nozzles. A correction processing unit is configured to perform a correction process corresponding to each of the plural ink ejection malfunction positions in the image. A head cleaning processing unit is configured to perform head cleaning for the recording head. Further, if the number of the detected ink ejection malfunction positions exceeds a predetermined upperlimit value when using a predetermined ink droplet size, the correction processing unit causes the head cleaning processing unit to perform head cleaning for the recording head and thereby decreases the number of the ink ejection malfunction positions.

Abstract: A cleaning device includes a sheet conveyance roller, and a cleaning unit that cleans a surface of the sheet conveyance roller. The cleaning unit includes a cleaning member that can come in contact with the surface of the sheet conveyance roller, and a pressing roller that presses the cleaning member against the surface of the sheet conveyance roller. The pressing roller includes a low Young's modulus area formed at least on a part of the pressing roller in a radial direction, the low Young's modulus area having a Young's modulus lower than a Young's modulus of the sheet conveyance roller. When the surface of the sheet conveyance roller is cleaned, the pressing roller is pressed against the sheet conveyance roller so as to elastically deform in the radial direction in a state where the cleaning member is sandwiched between the pressing roller and the sheet conveyance roller.

Abstract: A method for recovery of a recording head includes cleaning liquid supplying operation, wiping operation, and backflow operation. The recording head is connected to a cleaning liquid tank for storing cleaning liquid via a cleaning liquid supplying path. In the backflow operation, a liquid supply mechanism makes the cleaning liquid in the cleaning liquid supplying path to flow backward in a direction pointing from the cleaning liquid supplying openings to the cleaning liquid tank. The recording head includes an ink ejection region in which ink ejection openings are open, and a cleaning liquid supplying region which is arranged upstream of the ink ejection region in a wiping direction and in which cleaning liquid supplying openings are open. The backflow operation is performed after a wiper passes the cleaning liquid supplying region and before the wiper reaches the ink ejection region.
