  • Patent number: 8967759
    Abstract: 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.

  • Patent number: 8905516
    Abstract: According to the present invention, firstly, since the cleaning liquid is deposited onto the nozzle surface by the nozzle surface cleaning liquid deposition device, then it is possible to raise the dissolving effect, which is a chemical effect of dissolving adhering material which is adhering to the nozzle surface. Consequently, it is possible to remove the adhering material readily by subsequently wiping the nozzle surface with the wiping member, and hence the physical effects can also be improved. Furthermore, since the cleaning liquid is deposited so as to wet the wiping member, then it is possible to suppress the drawing out of liquid from the nozzles due to the absorbing characteristics of the wiping member, and therefore ejection defects due to solidification of drawn out liquid can be prevented. Consequently, it is possible to improve ejection stability of the droplet ejection head.

  • Patent number: 8888233
    Abstract: In a device to clean wiper elements of an inkjet print head of an ink dispenser of a printing apparatus having a chassis, a maintenance station is mounted on the chassis to allow travel of the maintenance station in at least one direction that causes the maintenance station to move past the inkjet print head. The maintenance station carries wiper elements that wipe ink from the surface of the inkjet print head as the maintenance station moves past the inkjet print head. An ink uptake unit is mounted at the chassis at a position past which the maintenance station travels, after traveling past the inkjet print head. The ink uptake unit includes material that transfers ink from the wipers to the material.

  • Patent number: 8857949
    Abstract: A liquid ejecting apparatus includes a liquid ejecting head having a nozzle formation surface with a nozzle that discharges a liquid. A cleaning member wipes the nozzle formation surface to remove liquid that has adhered thereto. An absorption member of a porous material deforms under pressure and includes an absorption surface that contacts the cleaning member to absorb liquid that has adhered thereto. A pressure member moves between a pressure position, in which the pressure member applies pressure to the absorption surface of the absorption member, and a non-pressure position, in which the pressure member does not apply pressure to the absorption surface. A movement mechanism moves the pressure member from the non-pressure position to the pressure position to cause the absorption member to deform, thereby dispersing the liquid absorbed by the absorption member from the cleaning member via the absorption surface into the interior of the absorption member.
