An exemplary grounding device includes an electrically conductive planar member having a hollow, central opening. Arms extend from inner edges of the hollow, central opening of the planar member. Each arm is angled relative to a surface of the planar member and each arm includes a facing portion having an electrically conductive cushion attached thereto. Each arm is approximately the same size and is configured to contact a shaft extending through the hollow, central opening of the planar member to form an electrical connection between the planar member and the shaft. The electrically conductive cushion is between the arm and the shaft. A tab projection extends from an outer edge of the planar member. Each tab projection is in the same plane as the planar member.

Grounding device with electrically conductive cushion

A ground plate includes an electrically conductive planar member having a long axis and a perpendicular short axis. The planar member has an elongated hexagonal shape having two opposing long sides, two opposing relatively shorter sides, and four angled sides between the long sides and the relatively shorter sides with a hollow central opening. Spring clips extend from inner edges of the hollow central opening. The inner edges from which the spring clips extend are parallel to the long axis. Each spring clip includes a distal end portion curving outward from the hollow central opening and is configured to contact a shaft extending through the hollow central opening to form an electrical connection between the planar member and the shaft. A tab projection extends from an outer edge of each of the relatively shorter sides. Each tab projection is in the same plane as the planar member.

Earth plate

Described herein is a device that generates a beam of light with uniform intensity. The device includes an array of light sources. The light generated passes through a beam splitter. One beam is used for feedback to maintain uniform intensity. The other beam passes through a barrel which is used to mold the beam with uniform intensity into the desired shape and to reduce divergence. The device can be used as part of a quality control system for testing a photoreceptor drum.
