  • Gear alignment
    Publication number: 20040151536
    Abstract: Guide ring arranged coaxially with a drive shaft includes locating and locking features ensuring proper orientation of drive and driven shafts, also ensuring proper backlash between gears mounted thereon. Guide ring is inserted through a keyed aperture of a mounting bracket and brought into proximity with the driven shaft frame. Rotation of motor and guide ring in first direction draws shafts into alignment; mounting bracket is attached to driven shaft frame. Motor and guide ring then rotated in opposite direction to second extreme position in which the motor is locked and driven shaft can rotate freely.

  • Registration system for a digital printer which prints multiple images on a sheet
    Patent number: 6373042
    Abstract: A printing apparatus places multiple images on a sheet, either by re-feeding the sheet through a duplex path back to a marking device, or by feeding the sheet to successive marking devices. An edge position detector upstream of the marking device determines the location of the sheet so that an image may be precisely placed on the sheet. The system ensures that images on both sides of a sheet are in registration with each other.
