  • Patent number: 11048987
    Abstract: A control unit determines as a sheet center actual position a center position of a print sheet, and adjusts a center position of the image to be printed on the basis of a difference from the sheet center actual position. Further, the control unit prints a main scale image along a primary scanning direction on one face of a print sheet for a test chart, prints a vernier scale image along the primary scanning direction on the other face of the print sheet, determines a deviation between a reference center position of the print engine and a reference center position of the line sensor on the basis of a scale mark of the main scale image that agrees with a scale mark of the vernier scale image, and moves a center position of the image to be printed so as to reduce the determined deviation.

  • Patent number: 9457603
    Abstract: An apparatus for cooling media sheets in a printer includes a number of cooling units, a conveyor having a first conveyor path adapted to feed the media sheets successively through the cooling units, and a switch adapted to deflect selected ones of the media sheets into a second conveyor path. The switch is disposed upstream of a last one of the cooling units and downstream of a first one of the cooling units. The second conveyor path bypasses the last one of the cooling units. The conveyor includes a decelerating mechanism configured to decelerate the sheets in the first conveyor path between the first one of the cooling units and the last one of the cooling units.

  • Patent number: 9329550
    Abstract: An image forming apparatus includes an operation panel including a display section that displays buttons, a touch panel section, and piezoelectric elements. The image forming apparatus also includes a vibration control section and a determination section. The vibration control section outputs a drive signal to the piezoelectric elements that causes vibration of the piezoelectric elements and the touch panel section. The determination section determines for each maintenance target whether the maintenance target is an inspection target that preferably undergoes maintenance within a preset period of a current time. Upon operation of a button while no inspection target is present, the vibration control section causes the touch panel and the piezoelectric elements to vibrate under a normal vibration condition.
