摘要： A charge removing member is arranged just upstream of an image transfer area along a continuous form transport path, between the last guiding portion and the transfer area, to remove accumulated charge on the continuous form. The charge removing member is alternatively a brush contactable to the form, a non-contact conductive member, a brush movable toward and away from the form, or a brush that acts as a guide member. Further alternatively, the brush contacts the form only during reverse feeding of the form, and in this case, is alternatively movable toward and away from the form, movable toward and away from the form in association with a transfer unit, or positioned to contact a straight form while being out of contact with a form bent by a transfer unit.

摘要： A fixing unit, used for fixing images on a recording sheet, includes a heat roller accommodating a heater, and a press roller movable between a retracted position and an operating position. The heat roller is rotated by a driving mechanism. A moving mechanism opens and closes a gap between the press roller and the heat roller by moving the press roller between the retracted position and the operating position. An assist gear rotates the press roller in a predetermined direction when the opening/closing mechanism moves the press roller toward the operating position.

摘要： A printer includes a tractor unit for feeding continuous form paper, encoders driven in synchronization with the tractor unit, and detecting sensors for detecting the encoders to generate feed pulses at a standard interval. The printer further includes a paper top sensor for detecting a leading edge of the continuous form paper to generate paper top signal and is arranged to control the feed of the paper based on the feed pulse generated after the paper top signal. In order to adjust the printing position on the paper in case where the scanning position is misaligned due to a manufacturing error, the position of the detecting sensors is adjustable with respect to the encoders to compensate for the error. Further, the position of the paper top sensor is adjustable with respect to the tractor unit in order to keep the relationship between the feed pulse and the paper top signal unchanged regardless of the adjustment of the detecting sensors.

摘要： An image forming apparatus includes a photosensitive drum, a developing device, a primary transfer part, a droplet ejecting unit and a controller. On the photosensitive drum, an electrostatic latent image is formed. The developing device forms a toner image by causing a developing agent to adhere to the electrostatic latent image. The primary transfer part transfers the toner image onto an intermediate transfer belt. The droplet ejecting unit ejects droplets onto the toner image on the photosensitive drum after forming the toner image on the photosensitive drum and before transferring the toner image to the transfer member. The controller controls an ejection area of the droplet ejecting unit in accordance with image information of the toner image.

摘要： A printing apparatus and a conveyance control method are provided, both capable of detecting a print medium conveying state highly precisely in an entire process of conveying the print medium being printed. For this purpose, the surface of the print medium placed on the belt and the surface of the belt are detected to acquire the moving distance or moving speed of the print medium. Based on the moving distance or moving speed thus obtained, the driving of the belt is controlled. Even in a situation where the object being detected switches from the print medium to the belt in the middle of the conveying operation, the measurement of the moving distance can be performed without interruption by the same detection method using the same optical sensor unit.

摘要： This invention includes an input operation unit which accepts the operation of selecting a first or a second printing medium and outputs information indicating the selected printing medium, a conveyance path, a conveyance mechanism which conveys the selected printing medium in the conveyance direction, and a control unit. The conveyance mechanism includes a main roller, a driven roller which presses the main roller through the selected printing medium, a rotation member having a cam shape, and an elastic member which deforms to change a pressing force in accordance with the rotational position of the rotation member. The control unit rotates the rotation member to the first rotational position when the first printing medium is selected, and rotates the rotation member to the second rotational position where the pressing force becomes smaller than that at the first rotational position when the second printing medium is selected.
