摘要： An image forming apparatus includes a recording head, an ejection detection unit, a cleaner, and a holder member. The ejection detection unit has an electrode member disposed in an area in which the electrode member is opposable to the head. The cleaner includes a cleaning member to remove droplets adhering to the electrode member. The ejection detection unit detects ejection or non-ejection of droplets by detection of electric changes of the electrode member generated when droplets ejected from nozzles of the head land on the electrode member in a state in which a potential difference is created between a nozzle face of the head and the electrode member and the nozzle face is opposed to the electrode member. The holder member supports the electrode member, and holds the cleaning member movable in parallel to a nozzle array direction in which the nozzles is arrayed in the head.

摘要： An image forming apparatus includes a recording head, an ejection detector, and a cleaner. The ejection detector detects ejection or non-ejection of droplets from the head and has an electrode member disposed in an area in which the electrode member is opposable to the head. The cleaner cleans the electrode member after ejection or non-ejection of droplets from nozzles of the head is detected by detection of electric changes of the electrode member generated when the droplets ejected from the nozzles land on the electrode member with a potential difference created between a nozzle face of the head and the electrode member and the nozzle face opposed to the electrode member. The cleaner includes a wiping member to wipe droplets adhering to the electrode member. The wiping member and the electrode member are configured to be relatively moved in parallel to a nozzle array direction to clean the electrode member.

摘要： A liquid discharge apparatus includes a color component divided data generation unit, a dot data generation processing unit, and a dot data segmentation processing unit. The color component divided data generation unit generates color component divided data from image data. The dot data generation processing unit applies a dot data generation mask to the color component divided data to generate dot data. The dot data segmentation processing unit applies a segmentation mask to the dot data to generate scan data. A width of the segmentation mask in a main scanning direction is different from a width of the dot data generation mask in the main scanning direction.

摘要： A liquid discharge apparatus is provided including a liquid discharge head, a cap, and a wiper. The liquid discharge head includes a nozzle plate having thereon a nozzle for discharging a liquid. The cap caps a surface of the nozzle plate. The wiper moves relative to the nozzle plate to wipe the surface of the nozzle plate. The surface of the nozzle plate has a cap contact region that is contactable with the cap. The wiper starts wiping from a wiping start position that is disposed between both end parts of the cap contact region in a direction of wiping. The wiper comes into contact with the surface of the nozzle plate at the wiping start position and moves in a first direction to wipe the surface of the nozzle plate, and thereafter moves in a second direction opposite the first direction to wipe the surface of the nozzle plate.

摘要： A liquid ejector includes a head having a plurality of nozzles arranged along a first direction of a nozzle surface of the head to eject a droplet from the nozzles, and an ejection detector to detect whether or not a droplet is ejected from the plurality of nozzles of the head by detecting an electrical change generated when the droplet lands onto the ejection detector. The ejection detector includes a droplet landing surface arranged opposed to the nozzle surface, a wiper to wipe the droplet off the droplet landing surface along the first direction, and a cleaner having a contact surface to remove the droplet adhered to the wiper after the wiper wipes the droplet landing surface. The contact surface has a curvature such that side ends of the wiper contacts with the contact surface at first, and then a center part of the wiper contacts the contact surface.

摘要： A liquid discharge apparatus includes a conveyance roller, a liquid discharge head, and a control device. The control device controls the head to discharge liquid onto a medium X times in the main scanning direction and Y times in the sub-scanning direction and controls the roller such that a position of a droplet on the medium discharged by an m-th discharge and a position of another droplet on the medium discharged by an (m+Y)-th discharge are same in the sub-scanning direction, where m is an integer not smaller than one and not greater than ((X−1)×Y). Where P is a circumferential length of the roller and L is a difference in a conveyance distance in the sub-scanning direction when the m-th discharge is compared with the (m+Y)-th discharge, the following relation is satisfied:

L=(n+(Δθ/2π))×P,



where |π−Δθ|
