Abstract: A system and method for optical alignment of a color imaging system includes illuminating a target plate with a laser beam. Photo-luminescent energy from the target plate is emitted in response to the laser beam. A color imaging system is aligned based on the photo-luminescent energy emitted at the target plate.

Abstract: A bag filler consisting of a single tubular member has a peripheral portion removed from one end thereof to form a hand grip while an opposing peripheral portion at the same end then forms a scoop, has its other end inserted into the open end of a bag to be filled, and the bag at both its ends is then turned about and within the associated ends of the tubular member so that an operator may with one hand hold both the open end of the bag and the hand grip of the tubular member for guiding the bag and bag filler into engagement with material from which the bag is to be filled, while the operator's other hand holds the bag and other end of the tubular member to propel the bag and bag filler.
