Abstract: An ejection apparatus includes: a first ejection unit configured to eject droplets on a recording medium conveyed in a conveyance direction to form an image for detection; a first detection unit disposed downstream of the first ejection unit and configured to detect the image for detection; a second ejection unit disposed downstream of the detection unit and configured to eject droplets on the recording medium; and a control unit configured to: predict a first elongation amount of the recording medium based on a first difference between a first set time period and a first detection time period from a reference time point to a first detection time point when the image for detection is detected by the first detection unit; and perform delay control on the second ejection unit for delaying an ejection timing of the second ejection unit based on the predicted elongation amount.

Abstract: An image processing apparatus includes a processor. The processor is configured to set an image position of a reference image in a transport direction of a recording medium to an arbitrary position on a specific page of the recording medium. The reference image is formed using a first color and serves as a reference for an image position of an image of a second color to be formed after the image of the first color is formed. The processor is also configured to adjust the image position for the second color on an adjacent page, located adjacently upstream of the specific page in the transport direction, by using image information of the reference image formed on the specific page.

Abstract: An image forming apparatus includes an image forming unit, first and second detectors, and a corrector. The image forming unit includes first and second image forming units disposed downstream of the first unit in a transport direction of a recording medium and causes the first and second units to form predetermined correction images onto the recording medium. The first detector is disposed downstream of the first unit and upstream of the second unit in the transport direction, and detects the correction image formed by the first unit. The second detector is disposed downstream of the second unit in the transport direction and detects the correction image formed by the second unit. The corrector corrects an image position of the second unit in a width direction of the recording medium by using the correction images formed by the first and second units and detected by the first and second detectors.

Abstract: A flash fixing apparatus effectively collect vapor gas produced at the time of fixation while fixing a toner image of medium by means off flashlight. In the flash fixation unit, vapor gas produced in flash fixation flows toward the medium transportation direction. Utilizing this phenomenon, a gas suction face is provided in a gas collector so as to receive the vapor gas flowing toward the medium transportation direction. Otherwise, a gas blast portion is provided at the rear stage of the gas collector. The vapor gas flows to the gas suction face naturally, bringing about improved gas collection efficiency.

Abstract: A continuous-medium-box feeding device feeds a continuous-medium box to a printing device printing on a continuous medium fed from the continuous-medium box containing the continuous medium. The continuous-medium-box feeding device includes a set table capable of sliding between a first position and a second position adjacent to the first position, and a stand-by table capable of sliding between the first position and a third position adjacent to the second position. At the first position, the continuous medium can be fed from the continuous-medium box to the printing device. At the second position, the continuous-medium box can be removed from the set table. At the second and third positions, a continuous-medium box containing a continuous medium to be printed on next can be placed on the stand-by table. In the continuous-medium-box feeding device, the stand-by table can feed the continuous-medium box on the set table positioned at the first position.

Abstract: Disclosed is an image forming apparatus for forming an image on a sheet. The image forming apparatus comprises a unit for forming a toner image on the sheet and a flash fixing unit for fixing the toner image onto the sheet by an emission of light from a flash lamp. The flash fixing unit includes a first unit having a first flash lamp disposed at the center and a second unit having second flash lamps disposed on both sides of the first flash lamp and exhibiting a light emitting energy larger than a light emitting energy of the first unit. The second flash lamps disposed at a pitch smaller than the pitch at which the first lamps are disposed. With this construction, the fixing energies at both ends of the flash fixing unit increase, and the fixing energy at the center decreases. It is therefore possible to prevent an ill-fixed state and improve a fixing efficiency.
