An ink-jet printing apparatus can restrict increasing of a cost due to sliding load of a flexible wiring board or an ink supply tube, permit down sizing of the apparatus, and prevent breakage of the flexible wiring board and rapture of the tube. The ink-jet printing apparatus employs a head ejecting ink and performing printing by ejecting ink on a printing medium from the head. The ink-jet printing apparatus includes a flexible wiring board electrically connecting the head and an electric board installed in a main body and having a curve portion, and a displacement restriction member restricting displacement of the flexible wiring board associated with movement of a carriage, the displacement restriction member having a construction with small sliding resistance for the flexible wiring board with respect to a portion contacting with the flexible wiring board.

An apparatus includes a liquid ejecting head capable of ejecting liquid from a plurality of ejection ports by driving a plurality of ejection energy generation elements corresponding to the plurality of ejection portions. The apparatus includes a wiping mechanism capable of wiping an ejection port face in which a plurality of ejection ports is arranged in the liquid ejecting head. The ink ejection from the plurality of ejection ports is performed in a manner of a plurality of divisions. A time interval from a last wiping to a next wiping is adjusted according to an interval of the ejection energy generating elements corresponding to an adjacent ejection port.
摘要:
A cleaning method for removing a recording ink from a surface of a recording material conveying belt of a recording apparatus. The method includes the steps of detecting a recording material jam; press contacting a cleaning member to a surface of the recording material conveying belt in response to the detected jam, thus removing from the belt surface an improper discharge of recording ink; and separating the cleaning member from the surface of the conveying belt after cleaning for a period of time. The period of time is determined based upon an amount of the recording ink discharged onto the conveying belt surface.
摘要:
A liquid ejecting apparatus, such as an ink-jet printing apparatus includes a blade for wiping a surface of a liquid ejecting head for ejecting a liquid and a device for cleaning the blade with achieving expansion of life and permitting efficient process. The apparatus achieves reduction of frequency of scrubbing contact between the blade and the liquid ejecting surface and high efficiency in recovery process associated with wiping operation and so forth. Also, by providing a washing liquid for the blade upon termination of printing, the blade may be maintained in sufficiently wetted condition.
摘要:
A recording apparatus builds an image at high quality without occurrence of malfunctions attributable to raised/recessed spots on the surface of a conveyance belt and insufficient dimensioning for the width of the conveyance belt, while preventing the interior of the recording apparatus from being contaminated with erroneously ejected ink. The recording apparatus includes a conveyance belt for conveying a recording sheet below four kinds of recording heads, and the conveyance belt has a joint line along which the opposite ends of a band-shaped material are joined to each other. In addition, the conveyance belt has a band-shaped colored portion which is located remote from the joint line by a predetermined distance. The colored portion is detected by an optical sensor, and a control unit controls the driving of the conveyance belt in response to a signal derived from the detection of the optical sensor.

An image forming apparatus having a movable separator to separate a recording medium from a feeding belt includes feeding structure for feeding an attached recording medium in a predetermined feeding direction. Image forming structure receives the recording medium from the feeding structure and forms images on the received recording medium. The separator is located on a downstream side of the image forming structure, and separates the attached recording medium from the feeding structure in a direction which is angled from the predetermined feeding direction. The separator moves to push the recording medium from a non-recording face thereof to a recording face thereof while the recording medium is stopped during intermittent feeding to cause even separation of the recording medium from the feeding structure.
摘要:
A registration adjusting is performed for reducing an error in registration adjustment due to tolerance in manufacturing of a linear encoder scale. In the method, a printing head located at a position closest to a center position among a plurality of printing heads arranged along a primary scanning direction is taken as a reference printing head for registration adjustment.
摘要:
A cleaning apparatus and method for removing a recording ink from a surface of a recording material conveying belt of a recording apparatus. The method includes the steps of contacting a blade member to a surface of the recording material conveying belt and contacting an ink absorber member to a surface of the recording material conveying belt, thus removing from the belt surface an improper discharge of recording ink.
摘要:
An ink jet textile printing apparatus for performing printing by reading an original image created by a designer, converting the original image into original data represented by an electric signal, retrieving the original data for processing to be output as image data, and recording data on cloth based on the image data. The ink jet textile printing apparatus has a first ink jet recording head provided upstream of a recording position, and a second ink jet recording head provided downstream thereof, and is provided with a drying unit located between the recording heads, whereby high-quality recorded images with less bleeding can be obtained by recording on a recording area again with the second ink jet recording head after drying the recording area on the cloth recorded by the first ink jet recording head with the drying unit.
