    摘要: An image forming apparatus includes a printing device to print, on a recording medium, a colorimetric pattern including a plurality of colorimetric patches; an imaging device; a conveyor to convey the recording medium in a conveyance direction; and circuitry. The circuitry causes the printing device to form a plurality of marker patterns on a side of the colorimetric pattern and at predetermined intervals in the conveyance direction so that one of the marker patterns is downstream from a first row of the colorimetric patches in the conveyance direction; causes the conveyor to convey the recording medium to position the colorimetric pattern at a reading position by the imaging device based on a distance between the plurality of marker patterns and the colorimetric pattern in the conveyance direction; and causes the imaging device to read the colorimetric pattern on the recording medium.

    摘要: An image forming apparatus includes a body, a recording head, a sub tank, a carriage, a main tank, a liquid feed unit, a displacement member, first and second detectors, first to third calculation units, a determination unit, and a supply control unit. When the first detector detects the displacement member, the determination unit determines a main scanning position of the carriage at which consumption amount of the liquid is equal to an amount corresponding to a difference calculated by the second unit, based on a relation calculated by the third unit. The control unit causes the feed unit to start supply of the liquid from the main tank to the sub tank when the carriage arrives at the main scanning position, and stop the supply when the liquid is supplied at an amount corresponding to a difference detected by the first unit after the first detector detects the displacement member.

    摘要: An image forming apparatus is provided including a drive source, a switching member, a drive force transmitter, a clutch, a controller, etc. The drive source drives a conveyer to rotate either normally or reversely. The switching member is swingable between an evacuation position and a striking position as a shaft rotates. The drive force transmitter transmits a drive force from the drive source to both the conveyer and the shaft. The clutch transmits the drive force to the shaft when being connected, and holds the switching member at the striking or evacuation position when being disconnected. The controller controls the drive source and the clutch such that the conveyer normally rotates to convey a manually-inserted recording medium from a manual conveyance path to an ejector and that the switching member swings from the evacuation position to the striking position, based on a signal indicating that the set position is wrong.

    摘要: An image forming apparatus includes an apparatus body, a recording head, head tanks, a carriage, main tanks, a liquid feeder, a liquid feed controller, a displacement member, a carriage-side sensor, and a body-side sensor. The liquid feed controller controls the carriage-side sensor to detect the displacement member of each head tank during a single scan of the carriage; obtains a current position of the displacement member; determines a liquid amount in each head tank or adjustment operation of the liquid amount based on both a comparison result of the current position and a determination position and a detection result of the carriage-side sensor, the determination position calculated from a detection position of the displacement member detected with the carriage-side sensor and set within a range in which the carriage-side sensor detects the displacement member; controls the feeder in accordance with a determination result; and adjusts the liquid amount.

    摘要: A distance detector includes a distance-measuring sensor, a first detection surface, a second detection surface, and processing circuitry. The first detection surface is perpendicular to an optical axis of the distance-measuring sensor. The second detection surface is behind or in front of the first detection surface with respect to the distance-measuring sensor. The second detection surface has two faces inclined with respect to the optical axis of the distance-measuring sensor. The first detection surface or the second detection surface is retractable from the distance-measuring sensor. The processing circuitry determines whether the first detection surface or the second detection surface is detected by the distance-measuring sensor and causes the distance detector to detect a distance from the distance-measuring sensor to the first detection surface based on detection of the first detection surface by the distance-measuring sensor.

    摘要: An image forming apparatus includes a sheet conveyance device; an image forming device including a sheet conveyance roller and a pressure roller; a memory; and a controller. The memory stores profile data indicating variation in conveyance amount in a circumferential direction due to eccentricity of the conveyance roller. The controller calculates, in intermittent conveyance processing, a correction value based on corresponding profile data for each of positions included in a width of an image to be formed in next image forming processing, the correction value being a difference between a predetermined conveyance amount and an actual conveyance amount; corrects a reference amount of rotation by a representative value of calculated correction values to calculate a corrected amount of rotation, the reference amount being an ideal amount of rotation of the conveyance roller that conveys a sheet by the predetermined conveyance amount; and rotates the conveyance roller by the corrected amount.

    摘要: A sub tank receives ink supplied from a main tank through a supply path. The sub tank includes a supply chamber that causes the ink to move toward a nozzle, and a pressure control chamber connected to the supply chamber through a connection part that can open/close. The pressure control chamber includes a pressure resistor that reduces the speed of the ink when the ink pressure rises in the supply path, and a volume changing member that is provided on at least a side of the connection part with respect to the pressure resistor in the ink flow direction, so that pressure in the pressure control chamber can be reduced by reducing the ink speed and increasing the volume of the pressure control chamber.
