Abstract:
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.
Abstract:
A liquid cartridge is detachably attachable to an apparatus body of an image forming apparatus. The liquid cartridge includes a cartridge case, an information memory element, and a holding unit. The cartridge case includes at least two dividable case parts. The at least two dividable case parts form a front face of the cartridge case to face the apparatus body when the liquid cartridge is attached to the apparatus body. An information memory element is held at the front face of the cartridge case. The holding unit is provided in one of the at least two dividable case parts to hold the information memory element with only the one of the at least two dividable case parts. The holding unit includes a groove to receive the information memory element and a displaceable claw to hold the information memory element between the groove and the claw.
Abstract:
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.

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.

Abstract:
A liquid container includes a case and a liquid containing bag contained in the case. The case includes an integrally formed hollow body having a front opening portion, a rear opening portion, and a supply-opening fixing portion. The supply-opening fixing portion is disposed on a front end of the hollow body and to which a supply opening portion of the liquid containing bag is fixedly attached. The case includes a front cover covering the front opening portion, and a rear cover covering the rear opening portion. The front opening portion is sized such that the liquid containing bag after use can be pulled out of the hollow body via the front opening portion. The rear opening portion is sized such that the liquid containing bag filled with ink can be inserted into the hollow body via the rear opening portion.
Abstract:
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.
Abstract:
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.
Abstract:
An image forming apparatus includes a recording head, an ejection detector, a cleaner and cleaning ejection controller. The ejection detector has a droplet landing member disposed in an area in which the droplet landing member faces the head. The ejection detector detects ejection or non-ejection by detecting electric change caused by landing of the droplets on the droplet landing member. The cleaner cleans a droplet landing surface of the droplet landing member. The cleaning ejection controller controls the recording head to eject droplets on the droplet landing surface for cleaning the droplet landing surface before cleaning the droplet landing surface by the cleaner. A quantity of the droplets for cleaning the droplet landing surface is greater than a quantity of the droplets for detecting ejection or non-ejection.
Abstract:
An ink cartridge removably mountable in an image forming apparatus includes a flexible storage member, a pressurization-space formation member, an output port, and an opening-and-closing assembly. The flexible storage member stores ink. The pressurization-space formation member hermetically houses the storage member and forms a pressurization space to which a fluid is supplied between the pressurization-space formation member and the storage member. The output port is connected to the storage member, through which the ink is supplied from the storage member to the image forming apparatus. The opening-and-closing assembly opens and closes between the output port and the storage member by the fluid supplied into the pressurization space.
