  • Patent number: 11952970
    Abstract: A fuel booster system having a fuel inlet port, a fuel outlet port, and a fuel accumulator fluidically coupled to both ports. The fuel inlet port allows fuel to be delivered to the fuel accumulator and the fuel outlet port is in fluid communication with a combustion engine to deliver fuel from the fuel booster system to the combustion engine. A source of pressurized gas is also fluidically coupled to the fuel accumulator to deliver pressurized gas through a gas port in one end of the fuel accumulator. A piston is located within the fuel accumulator and the source of pressurized gas can be discharged into the fuel accumulator to force accumulated fuel from the fuel accumulator and to the engine when the fuel booster system determines that the engine needs more fuel.

  • Patent number: 11947302
    Abstract: According to some examples, a skew detection device comprises a first roller rotatable around a first axis, a second roller rotatable around a second axis, a first sensor, and a second sensor. The first sensor measures a first rotation parameter from the first roller and the second sensor measures a second rotation parameter from the second roller. A movement of a print media over the device rotates the first contact roller and the second roller, and a controller determines a skew of the print media based on the first and second rotation parameters captured by the first sensor and the second sensor.

  • Patent number: 11919741
    Abstract: A sheet stacking apparatus includes a pair of sheet alignment mechanisms disposed to face each other in a direction of conveyance of a sheet or in a direction orthogonal to the direction of conveyance. Each one of the pair of sheet alignment mechanisms includes an aligning member, an elastic member, a driver, and a driving source. The aligning member reciprocates with reference to the sheet. The elastic member extends due to reaction force generated in response to pressing force applied to an edge of the sheet by the aligning member when a size of the sheet is larger than a prescribed size. The driver is coupled to the aligning member via the elastic member. The driving source transfers a driving force to the driver.

  • Patent number: 11796943
    Abstract: A fixing device includes an endless fixing belt, a heating roller that heats the fixing belt, a steering roller, and a pressurization rotating member. The steering roller is controlled to swing to move the fixing belt to a prescribed position. The pressurization rotating member pressurizes and forms a fixing nip portion with the fixing belt. When a recording material bearing unfixed toner is nipped and conveyed to the fixing nip portion, an unfixed toner image is fixed to the recording material. A single inclination operation that inclines the steering roller results in an inclination angle that is smaller when a recording material having a length greater than a predetermined length in a recording material conveying direction is conveyed to the fixing nip portion than when a recording material having a length less than or equal to the predetermined length in the conveying direction is conveyed to the fixing nip portion.

  • Patent number: 10488805
    Abstract: An image forming apparatus includes the following. An upstream second conveying roller and a downstream second conveying roller form a loop on the long sheet. A deviation amount detector detects a deviation amount of the long sheet. A loop amount detector detects a loop amount in two positions in a width direction. A speed controller controls a rotating speed of the upstream second conveying roller and the downstream second conveying roller based on a deviation amount and a difference of loop amounts in two positions. Each of the upstream second conveying roller and the downstream second conveying roller includes a near roller and a far roller. The speed controller controls the rotating speed of the near roller and the far roller based on the deviation amount and the difference of the loop amounts in the two positions.

  • Patent number: 10377128
    Abstract: A method is provided for controlling a web in a printing apparatus The printing apparatus includes a transport assembly for moving the web through a transport path along a printing unit for printing an image onto a print area of the web. The method includes feeding the web from a supply roll through the transport path to the transport assembly; and switching the printing apparatus to a ready-to-print mode, wherein the printing unit does not print an image on the web and the web is maintained ready to be printed on. In a printing mode after the ready-to print mode, the following steps are performed: moving the web through the transport path in a transport direction along the printing unit by the transport assembly; and printing the image onto the print area of the web by the printing unit. The image is printed by applying an image material, which solidifies on the web during the printing step.

  • Patent number: 10370212
    Abstract: A registration system includes nip rollers for conveying a sheet in a process direction when the nip rollers are in an engaged position, and first and second sets of omnidirectional rollers arranged perpendicularly to each other, for conveying the sheet in the process and cross-process directions, respectively. The omnidirectional rollers each allow the sheet to slide, relative to the omnidirectional roller, in a direction parallel to an axis of rotation of the omnidirectional roller. The nip-rollers are movable from the engaged position to a disengaged position, in which the first pair of omnidirectional rollers convey the sheet in the process direction. A feedback system includes sensors for determining registration errors of the sheet and a control system controls the omnidirectional rollers to reduce the registration errors in the sheet while the nip-rollers are in the disengaged position.

  • Patent number: 10227194
    Abstract: In a sheet conveyor, a stopper piece of a sheet stopper temporarily stops a sheet supported on a sheet tray, and a pickup roller conveys the sheet from the sheet tray in a sheet conveying direction. A first sheet sensor disposed upstream of a registration roller and downstream of the stopper piece in the sheet conveying direction detects a leading edge of the sheet, and a second sheet sensor disposed downstream of the registration roller detects the leading edge of the sheet. A first contact member of the first sheet sensor receives the leading edge of the sheet. A second contact member of the second sheet sensor receives the leading edge of the sheet. The stopper piece, the first contact member, and the second contact member are offset from each other in a direction perpendicular to the sheet conveying direction and unaligned with each other in the sheet conveying direction.
