摘要： A sheet-supplying device has a sheet-accommodating tray, a raising/lowering unit, a first position sensor, a second position sensor, a controlling unit. The raising/lowering unit raises and lowers the sheet-accommodating tray substantially. The first position sensor detects a first position indicating a position in the stacked direction of one end portion of a topmost sheet stacked in the sheet-accommodating tray. The second position sensor detects a second position indicating a position in the stacked direction of another end portion of the topmost sheet. The controlling unit controls the raising/lowering unit to raise or lower the sheet-accommodating tray based on both the first position detected by the first position sensor and the second position detected by the second position sensor so that one end of the topmost sheet in the stacked status is positioned at a prescribed position in the stacked direction.

摘要： A printing apparatus includes a printing device to print, on a sheet, a detection mark for acquiring an amount of deviation of an image, a detection device to read a position of the detection mark and acquire the amount of deviation of the position of the detection mark, and control circuitry to perform correction according to the amount of deviation. The circuitry prints the detection marks on both faces of the sheet in duplex printing, reads the detection marks on both faces with the detection device, calculates a first correction value from the position of the detection mark on a first face on which printing is performed first, calculates a second correction value from the position of the detection mark on a second face on which printing is performed later, and calculates a third correction value from the positions of the detection marks on the first and second faces.
