An ink removal system includes a drip bib and a flexible member. The drip bib collects melted ink flowing down the face of a printhead and the flexible member captures ink dropping from the drip bib after an ink receptacle has received most of the ink collected by the drip bib. When the ink receptacle returns to the position where the receptacle catches melted ink from the drip bib, the receptacle also bends the flexible member and releases the captured ink, which falls into the ink receptacle.

Apparatus and method for collecting and expelling phase change ink in a printer

An apparatus which develops an electrostatic latent image recorded on a photoconductive member with toner particles. A donor member is spaced from the photoconductive member and transports toner particles to a development zone adjacent the photoconductive member. Electrode wires are positioned in the development zone between the photoconductive member and the donor member. The electrode wires are electrically biased to detach toner particles from the donor member to form a cloud of toner particles in the development zone. Toner particles detached from the toner particle cloud develop the latent image. The electrode wires are adjustably supported in tension adjacent the donor member.

Development system having tensioned electrode wires

An air jet assisted ion projection machine including an image bearing member, an ion generator, an inlet channel and an outlet channel connected to the ion generator, a source of air in communication with the inlet channel to move ions through the outlet channel, the outlet channel being located near the image bearing member, modulation means located adjacent the outlet channel for controlling the passage of ions therethrough to the image bearing member, and an ozone filter system for filtering ozone generated within the machine, the ozone filtering system comprising an ozone filter supported within the machine, and an air path defined by the machine geometry between the outlet channel and the ozone filter, the source of air for moving ions also conveying ozone in the air path to the ozone filter.

Apparatus for dispensing particulate material has a substantially enclosed rigid housing with longitudinally disposed walls and parallel side walls having an opening in the housing for dispensing particulate material therefrom and a flexible sheet-like inner liner conformable to at least some of the longitudinal walls of the housing, one end of which is attached to a portion of the housing the other end of which is attached to a take-up roll for the inner liner which conforms to the longitudinal walls when the housing is filled with particulate material. The portion of the housing to which the inner liner is attached, the take-up roll and the dispensing opening are disposed relative to each other such that as the sheet-like inner liner is taken up by the take-up roll the particulate material is transported by the inner liner toward the dispensing opening and dispensed therethrough. In a preferred embodiment, the particulate dispenser is a developer housing for an electrostatographic printing machine.

A device for sealing a space between two adjacent surfaces comprises a seal holder, a flexible thin sheet-like member folded back on itself forming a deformed cylinder having a generally tear-drop shaped cross section, the two ends of the folded back sheet-like member being held and retained in close proximity by the seal holder to maintain the tear-drop shaped cross section with the seal holder being mounted on one surface relative to the other surface such that a portion of the deformed cylinder forms at least a line contact seal engagement with that surface. In a preferred embodiment, the two ends of the folded back sheet-like member have end portions folded over in the same direction, one nesting inside the other forming an acute angle with an adjacent portion of the deformed cylinder with the width of the outermost folded end portion being greater than the width of the innermost folded portion thereby providing an achoring hook for supporting engagement with the seal holder wherein the innermost folded end portion is permitted to move axially relative to the outermost folded end portion to maintain line contact sealing engagement with the surface. The seal holder includes a groove-like chamber for supporting the seal anchoring hook, a narrow insertion slot and a hook retaining lip. In a preferred application, a sealing device is used in sealing a developer and/or cleaner housing in eletrostatographic reproducing apparatus.

Tear drop seal

An apparatus in which successive flexible sheets are advanced from a stack. The stack of sheets are held in a substantially vertical orientation. Successive outermost sheets from one side of the stack are fed, in seriatim in a direction substantially opposed to the direction of the gravitational force exerted thereon. The stack of sheets is moved toward a sheet feeder so as to position successive outermost sheets of one side thereof in a feeding relationship therewith. In addition, the stack holder moves from an operative position, in which the sheets are in a sheet feeding relationship, to an inoperative position for loading a new stack therein.

Sheet feeder-stacker

In a reproducing machine having copy sheets advancing through a processor to have information recorded thereon, it is necessary to be readily able to remove jammed sheets therefrom. A display on the reproducing machine indicates to the operator when a jam occurs. In response to the occurrence of a jam, all of the sheets in the processor are automatically freed from their respective sheet transports. In this way, the operator may readily remove the jammed sheet from the respective transport.
