A first cutter and a second cutter are arranged in the vicinity of the processing unit. The first cutter is configured to cut the sheet on an upstream of the processing unit. The second cutter is configured to cut the sheet on a downstream thereof. When the processing unit is pulled, the sheet is cut on the upstream and downstream of the processing unit.

Abstract: A sheet is cut between a first conveying unit and a second conveying unit in a state in which the first and second conveying units halt and in which an upstream conveying unit conveys the sheet at a first speed; after the sheet is cut, the first conveying unit conveys the sheet at a second speed higher than the first speed to reduce a slack formed during the halting; after the sheet is cut, the second conveying unit conveys the downstream-side sheet at a third speed higher than the first speed; if the third conveying unit is nipping the sheet during cutting, the third conveying unit conveys the sheet at the third speed; and if the third conveying unit is not nipping the sheet, the third conveying unit conveys the sheet at the third speed or a fourth speed after the detecting unit detects the sheet.

Abstract: An apparatus for performing duplex printing having a sheet feeding unit, a printing unit, a cutter unit, a drying unit, and a reverse unit. In the duplex printing, the printing unit prints a plurality of images on a first surface of a sheet fed from the sheet feeding unit. The sheet is a continuous sheet. The sheet printed on the first surface passes through the drying unit and is led to the reverse unit. The reverse unit feeds the reversed sheet to the printing unit and the printing unit prints a plurality of images on a second surface that is a back of the first surface of the sheet fed from the reverse unit. The cutter unit cuts the sheet printed on the second surface into a plurality of cut sheets each having the image printed thereon. The cut sheets pass through the drying unit and are ejected.

Abstract: In a first step, a sheet is conveyed in a direction, whereby a leading end portion of the sheet is fed to a position between a decurl roller and a decurl pinch roller, which are in positions spaced apart from each other. In a second step, the leading end portion of the sheet is curved and held by causing the decurl pinch roller to come close to or press against the decurl roller. In a third step, the leading end portion of the sheet is withdrawn from between the decurl roller and the decurl pinch roller by conveying the sheet in a direction opposed to the conveying direction. After executing the first to third steps, the sheet is conveyed in the conveying direction through the first step while the sheet is curved by the decurl roller.

Abstract: A method includes pulling out and conveying a sheet having splice portions, acquiring information relating to a position of an indentation on the sheet formed in addition to a splice portion, and performing processing on the sheet but a position corresponding to the acquired position of the indentation and its vicinity.

Abstract: A printing medium transport apparatus and method and printing apparatus which is capable of properly transporting a printing medium by the cooperation of two rollers under independent drive without incurring the complication, size increase and price increase of the apparatus. In the course of transporting a sheet by the cooperation of feed and transport rollers, deceleration/stop control is made on feed and transport motors to be respectively driven such that the rollers are simultaneously stopped from rotating. When the transport roller stops from rotating that is located downstream side on a transport path of a printing medium in case the feed roller is rotating that is located upstream side on the transport path, the feed motor driving the feed roller is forcibly stopped.

Abstract: This invention provides a small and simple construction to drive a mechanism for maintaining a printing performance of a print head. In one preferred mode of the invention, a recovery device to maintain the printing performance of the print head has a suction pump unit, a capping unit and a wiping unit. The suction pump unit is driven through a spring clutch mechanism by an LF motor in the print sheet transport unit as a drive source. The capping unit and the wiping unit are driven by an AP motor as a drive source in a rotary dead zone set for a paper feed unit that feeds the print sheet to a transport unit. A piston pump is suited for use in a recovery operation to maintain the function of the print head.

Abstract: An ink-jet printing apparatus includes a recovery section having a pump for discharging ink from an ink-ejection portion of a printing head by the application of a suction force thereto. In the recovery section, the pump and the waste ink absorber for retaining the waste ink are disposed approximately at the same height so that the printing apparatus becomes thinner and is improved in portability. An interior space having a sealed waste ink flow passage for connecting the recovery section to the waste ink absorber is provided, in which a flow passage absorber is accommodated so that a gap is formed from a connection with the discharging port of the pump to a connection with the waste ink absorber and is further connected to the waste ink absorber. Thereby, the waste ink is effectively and securely guided to the waste ink absorber and securely retained there, without leakage.

Abstract: For eliminating waste of ink and achieving high charging efficiency with a reduced charging time where a printing head is equipped with a second tank for reserving a predetermined amount of ink and a supply system is configured to supply ink from a first tank to the second tank intermittently, the second tank is provided with a variable internal volume. The internal volume is varied to cause the second tank itself to function as an actuator for charging ink and performing a venting process. Specifically, the internal volume is forcibly reduced to cause a reverse flow of a gas residing in the second tank along with ink into the first tank, which makes it possible to generate of waste ink that is released to the outside. A normal charging operation can be completed simply by causing a change in the opposite direction (the direction of increasing the internal volume). Relatedly, the second tank may be provided with a member for holding ink and generating a negative pressure originating from an elastic force.
