An enlarged buckle chamber is positioned within an easily accessible, copy sheet transport path and used to compile sheets during fault cycle down in copiers/printers whenever sheets are prevented from reaching the output in sequence by jammed sheets. The user can then clear most jams by accessing the jam area plus the "easy to reach" area where internally purged sheet are gathered, thereby avoiding having paper distributed all over the paper path.

A printing device is provided comprising multiple marking engines including at least one marking engine and at least another marking engine that during operation place marks on output media. A power supply is further provided that selectively supplies selected levels of power from the at least one marking engine to the at least another marking engine for selected times so as to rotate readiness from the at least one marking engine to the at least another marking engine for operation to and from a dormant state. Power from the power supply is selectively distributed to the multiple marking engines so that the at least one marking engine is readied for operation while the at least another marking engine is removed from readiness.

In a printing apparatus, verification of the correctness of a particular replaceable module takes place before an operating element of the printing apparatus fully engages the replaceable module. A printing apparatus coupler establishes a communication link with a tag on the replaceable module as the replaceable module is being inserted into the printing apparatus. The printing apparatus coupler receives module identifying information from the tag. The coupler determines from the identifying information whether the replaceable module is appropriate for that location in that printing apparatus, and performs either an acceptance action to accept the replaceable module, or a rejection action to reject the module.

A high capacity copy sheet supplying system for reproduction apparatus, in which a large and heavy stack of copy sheets may be much more easily and accurately loaded therein, by a sheet supplying container insertable into the sheet supply input. This container has sheet stack confining side walls, a bottom wall with plural spaced apertures, and a false bottom tray insert loosely overlying that bottom wall on which the stack of copy sheets is supported. Plural lift rods are operatively connecting with an elevator system to provide movement of the lift rods up through the apertures in the bottom wall of the sheet supplying container, to engage and lift the false bottom tray and the large and heavy stack of copy sheets supported thereon by engagement of the ends of the lift rods, so as to lift up the large stack of copy sheets from within the sheet supplying container into engagement with a fixed position sheet feeder, and then to automatically maintain feeding of sheets from the top of the stack by maintaining with the elevator system the level of the top of the stack until the sheets are depleted by the sheet feeder. The same container can be used for an output stacker. It also may have a contents viewing window.

In a hard copy document production machine using a plurality of different type cartridges containing different document production consumable materials, an orientation-independent cartridge type discriminating system assembly suitable for enabling non-burdensome orientation-independent loading of a correct cartridge into a cartridge opening in the machine, and for resiliently intercepting and preventing loading of an incorrect cartridge into the cartridge opening. The discriminating system assembly includes a resilient assembly mounted to a portion of the frame of the machine defining the cartridge opening, a first spring member, and a pivotable elongate member connected to the spring member for providing resilient cartridge contact with a cartridge being inserted. The elongate member has a displaceable portion, and a cartridge blocking portion spaced from the displaceable portion in a direction of cartridge insertion. The displaceable portion has a cartridge-type first specific distance measured from the cartridge blocking portion, and the cartridge blocking portion has a first position within the cartridge opening, and a second position adjacent the cartridge opening. The discriminating system assembly also includes a displacer device formed on a surface of a cartridge being inserted into the cartridge opening, and has a cartridge-type specific second distance measured from a lead edge of a cartridge of the type of cartridge being inserted. The cartridge-type specific second distance determines a correct cartridge when it is equal to the cartridge-type specific first distance, and the displacer device extends continuously and uniformly in a direction transverse to the direction of cartridge insertion, so as to enable non-burdensome, orientation-independent loading of a cartridge into the cartridge opening.

A device is provided for storing a supply of particles for use in a developer unit of an electrophotographic printing machine. The device includes an open ended container which has a chamber in communication with the open end of the container. The particles are stored in the chamber of the container. The device also includes a feature associated with the container which extends substantially the length of the container, for urging the marking particles in the chamber toward the center of the chamber.

A battery-powered apparatus, for inducing air flow past a product capable of being vaporized, includes a compact housing that comprises a hollow outer shell and a hollow, generally cylindrical inner shell, having an axis, on which the operating components of the apparatus are supported. The inner shell is mounted with the outer shell by a hinge to pivot substantially on the axis between closed and open positions. In the closed position the inner shell compliments the outer shell to define an enclosed space and shield the apparatus components. In the open position, the inner shell is nested within the outer shell to expose the apparatus components. The product and a battery for powering the apparatus may be assembled into a cartridge formed to be received in the apparatus housing. Electrical battery contacts and a support for the cartridge in the housing are also disclosed.

A device for releasing a volatile substance into the environment in a controlled manner comprises a reservoir of substance-absorbent material, for storing the substance, that is encapsulated in an envelope, at least a portion of which comprises a permeable material having porosity at least equal to ultramicroporosity. The permeable envelope portion has a greater affinity for the substance than does the reservoir material. The remainder of the envelope comprises a material impermeable to the substance. Accordingly, the substance permeates through the permeable envelope portion to be released therefrom in vapor form into the environment.
