Abstract: An all terrain adapter for a wheelchair that removably clamps onto the foot support of the wheelchair and supports a relatively large diameter, slightly inclined swivelling nose gear wheel at an extended distance from the foot support to stabilize the wheelchair when it is being pushed over soft or uneven surfaces and which swivels around when the wheelchair is moved forward to lift the front wheels of the wheelchair clear of the ground.

Abstract: A method, a computer readable medium and an apparatus for modifying a printing process in response to an environmental condition received via a network. In the method, the environmental condition is received via the network and the printing process is modified in response to the environmental condition. In the computer readable medium, software embedded in the medium includes executable code to perform the above mentioned method. In the apparatus, a printing device is configured to apply a colorant to a print medium and a controller is configured to modify the printing device based on the environmental condition received via the network.

Abstract: A print cartridge according to a particular embodiment of the invention includes a housing and a seal disposed within the housing. The seal includes a longitudinal section having a first end and a second end, a first lateral section connected to and extending from the first end of the longitudinal section, and a second lateral section connected to and extending from the second end of the longitudinal section. The longitudinal section, the first lateral section, and the second lateral section are arranged to be generally continuous and to generally prevent toner leakage from the print cartridge.

Abstract: Estimating toner levels. A method embodiment includes maintaining a running pulse width count, sensing a toner level, and comparing the running pulse width count with an expected pulse width count to estimate a toner level. If the estimated toner level deviates from the sensed toner level, the running pulse width count and the sensed toner level are used to estimate the remaining toner level.

Abstract: The present invention includes a removable cover used to isolate a photoconductor drum from at least one other component in a toner cartridge. The photoconductor drum includes a cylinder coated with a photoconductive substance. Another embodiment includes a method of reducing electrostatic charges on the photoconductor drum including the steps of isolating the photoconductor drum from other components in a toner cartridge with a removable cover, removing the removable cover prior to insertion of the toner cartridge into an image device and inserting the toner cartridge into the image device.

Abstract: A method and a device for forming an image upon a medium using toner is provided. The device includes a photosensitive drum, a toner chamber having an interior cavity and at least one toner charge applying member between the drum and the chamber. The at least one charge applying member is configured to apply an electrical charge to toner particles within the cavity. The cavity is adjustable, whereby the cavity is adjusted to improve charging of the toner particles.

Abstract: The present invention is directed to a sealing mechanism for use in a toner cartridge. The sealing mechanism includes a developer roller and a toner plow. The developer roller has an outer cylindrical surface. The toner plow includes a concave contact region configured to mate with the outer cylindrical surface of the developer roller and a toner plow face placed at an acute angle with respect to a longitudinal axis of the developer roller.

Abstract: The present invention includes a sealing mechanism for use in a cartridge having a roller having an undulant annular channel and a flexible seal having a follower where the follower is configured to engage the undulant annular channel. Rotation of the roller induces a laterally reciprocating motion of the flexible seal with respect to the roller. Another embodiment of the present invention includes a method of reducing toner leakage in a cartridge comprising the steps of engaging a follower of a flexible seal within an undulant annular channel formed in a roller and rotating the roller to induce a laterally reciprocating motion in the flexible seal. When toner is applied to the roller in the vicinity of the flexible seal, the laterally reciprocating motion of the flexible seal sweeps toner in a direction away from the undulant annular channel.

Abstract: The present invention includes a toner cartridge having a developer roller having a cylindrical exterior surface with a tapering ramped channel formed in the surface of at least one end of the developer roller. The tapering ramped channel having a narrow proximal end nearest the at least one end of the developer roller and a wide distal end furthest from the at least one end of the developer roller. The narrow proximal end of the tapering ramped channel extends deeper into the surface of the developer roller than the wide distal end. The tapering ramped channel functions to propel toner particles or other fluid accumulating against an end seal away from the seal, toward a central portion of the developer roller.
