Abstract: A cleaning station for removing residual toner from a moving toner transfer surface includes a rotating brush and a scraper blade that is held away from the toner transfer surface when toner images are being transferred to recording media, such as sheets of paper. On a periodic basis, when toner images are not being transferred to the recording media, the scraper blade is moved into contact with the toner transfer surface to remove agglomerated toner therefrom, with continued operation of the rotating brush.

Abstract: A document feeder for automatically inverting a duplexed original so that the second side may be copied. The inverting mechanism is a turnaround roll located at the exit of the copy station. The inverting mechanism cooperates with rollers located above the document glass for moving documents thereacross. The rollers are inclined at an angle to the direction of paper movement in order to position paper against a side reference edge. When receiving a document from the turnaround roll and moving it in the reverse direction, the inclination of the rollers is removed or altered to a minus angle. Alternatively, a second set of rollers, inclined at a minus angle, are brought into active use when documents are moved in the reverse direction.

Abstract: Disclosed are apparatus and methods for impregnating oil into a lubricating pad for use in a journal box. A conveyor locates a bag containing a dry pad below an oil dispensing spout. If desirable or for particularly large bags and pads, a vacuum suction may be applied to opposite sides of the open upper end of the bag to hold it open. The spout is lowered and oil is dispensed into the bag. After the spout is raised, the bag containing the pad and oil is conveyed between a pair of platens which compress the bag and pad therebetween substantially fully exhausting air from the bag. While maintaining the bag and pad compressed, the open end of the bag is hermetically sealed. Upon movement of the platens away from one another, the pad expands within the bag with consequent impregnation of oil into the pad.
