  • Patent number: 4226410
    Abstract: Fanfold paper emerges from an outfeed slot in a printer along a paper guide extender and falls by gravity into a paper basket to resume its original fanfold configuration. The paper slides between the extender and an upper paper forming guide which is slightly curled at its lower end to force the paper against the lower end of the paper guide extender to cause the paper to neatly fan fold within the basket.A wedge-shaped member is preferably provided upon the floor of the paper basket to urge the stacked paper into an inverted, slighty V-shaped configuration to further assure neat stacking and prevent corners of the paper from catching a perforation in the paper which would otherwise prevent neat stacking.

  • Patent number: 3991871
    Abstract: A print head for impact printers of the dot matrix type comprising a hollow die cast housing having solenoids mounted upon a rear wall thereof and having print wires driven thereby and extending through the rear wall and hollow housing toward the forward end. A plastic bearing is releasably mounted in the forward wall and serves as a low friction bearing for the reciprocating print wires and to prevent abrasive wear of the print wires when in the retracted position. The guide means mounted within the housing and intermediate the forward and rearward ends thereof support guide tubes for maintaining relative positioning of the print wires as well as maintaining their desired natural curvature.The plastic bearing is formed of a plastic material for significantly increasing operating life and which is compliant to attenuate a significant amount of side loading due to impact. The plastic bearings are admixed with additives to make the bearings self lubricating.
