Patent number: 8905516Abstract: 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.Type: GrantFiled: December 31, 2012Date of Patent: December 9, 2014Assignee: FUJIFILM CorporationInventor: Hiroshi Inoue

Patent number: 8870342Abstract: According to an inkjet recording apparatus as an aspect of the present invention, the nozzle surface is wiped by a wiping member which rotates about an axle perpendicular to the nozzle surface. Consequently, the nozzle surface can be wiped in multiple directions and it is possible effectively to prevent deterioration of the lyophobic film, or adhering material being pushed inside the nozzles, due to wiping in one direction only. Furthermore, since a composition which rotates only the wiping member is adopted, then the composition of the wiping apparatus can be made compact.Type: GrantFiled: September 14, 2012Date of Patent: October 28, 2014Assignee: FUJIFILM CorporationInventor: Hiroshi Inoue

Patent number: 8870343Abstract: An ink jet recording apparatus includes a recording head, a carriage, a wiping unit, and a control unit. The recording head includes a discharging port surface provided with a first discharging port row group having at least one discharge port row formed by arraying a plurality of discharging ports in a predetermined direction and a second discharging port row group having at least one discharge port row formed by arraying a plurality of discharging ports in a predetermined direction. The carriage causes the recording head to scan reciprocally in a direction intersecting the predetermined direction. The wiping unit includes a sheet member for wiping the discharge port surface and a winding device to wind the sheet member. The control unit controls the winding device so that the first discharge port row group and the second discharge port row group are wiped with different areas of the sheet member.Type: GrantFiled: March 14, 2013Date of Patent: October 28, 2014Assignee: Canon Kabushiki KaishaInventors: Hiroaki Komatsu, Masaya Uetsuki, Kazuo Suzuki, Toshimitsu Danzuka, Masataka Kato, Tsuyoshi Ibe, Asako Tomida

Patent number: 8870344Abstract: A method includes applying a nominal back pressure to a fluid ejection assembly and nozzles to form a first amount of back pressure therein by a back pressure regulator. The method also includes applying a first pressure to lower the first amount of back pressure within the fluid ejection assembly and the nozzles to form a second amount of back pressure therein by a pressurization module in response to an activation of a cleaning operation. The method also includes moving at least one of the fluid ejection assembly and a wicking member against each other to perform the cleaning operation. The wicking member moves relative to the fluid ejection assembly against and across the nozzle surface to transfer fluid residue from at least one of the nozzle surface and the nozzles to a portion of the wicking member to form a used wicking member portion.Type: GrantFiled: March 19, 2013Date of Patent: October 28, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Scott Martin, Thomas M Sabo, Christopher J Arnold

Printer Inkjet Head Cleaning System for Waste Ink Collection and Inkjet Head Cleaning and Protection
Publication number: 20140307026Abstract: A printer inkjet head cleaning system for waste ink collection and inkjet head cleaning and protection comprises a frame, a pushing device and a cleaning device. An accommodating space is disposed inside the frame. A horizontal rail and an elevating rail are correspondingly disposed on two lateral sides of the frame respectively. A cover used for protecting an inkjet head is disposed on the pushing device. Two sides of the pushing device are movably coupled on the horizontal rails so that the pushing device can displace on the horizontal rails horizontally. A scraper is disposed on the cleaning device. Two sides of the cleaning device are movably coupled on the elevating rails. An end of the cleaning device is connected with the pushing device so that the cleaning device can displace on the elevating rails when the pushing device moves forward and backward.Type: ApplicationFiled: April 16, 2013Publication date: October 16, 2014Applicant: GREAT COMPUTER CORPORATIONInventors: Chen-Chien TSAI, Chia-Liang LU, Hui-Te YU -
Patent number: 8857950Abstract: A liquid ejection device includes a head, a medium supporting section and a first member. The head has a nozzle configured to eject a liquid onto a recording medium. The head is configured to move in a head travel direction. The medium supporting section is configured to support the recording medium. The first member has a curving face. The first member is disposed in a position overlapping the head travel direction and not overlapping the medium supporting section and the recording medium supported on the medium supporting section in a plan view. The first member is arranged so that the curving face faces a nozzle face of the head on which the nozzle is formed when the first member faces the head. The head is further configured to eject the liquid onto the curving face of the first member when the head faces the first member.Type: GrantFiled: November 1, 2013Date of Patent: October 14, 2014Assignee: Seiko Epson CorporationInventor: Nobuaki Kamiyama

Patent number: 8851664Abstract: According to aspects described herein, there is disclosed a marking station maintenance apparatus comprising a cart frame moveable along a rail support track for passing a marking station. The marking station is configured to mark a substrate media sheet. A first motion support assembly facilitates motion of the cart frame along at least a first portion of the rail support track. The first motion support assembly extends from the cart frame. The first motion support assembly includes a glide surface providing a non-contact bearing support between an air-bearing surface of the first portion of the rail support track and the glide surface. A marking station cleaner is disposed on the cart frame and configured to clean a marking element of the marking station as the cart frame passes the marking station.Type: GrantFiled: November 6, 2012Date of Patent: October 7, 2014Assignee: Xerox CorporationInventor: James Joseph Spence
