摘要:
A gear and a method for combining a first gear with a second gear including the steps of moving the first gear relative to the second gear such that a first tooth of the first gear contacts a second tooth of the second gear, pressing the first tooth of the first gear against the second tooth of the second gear such that a resultant force is not directed to a center of at least one of the first gear or the second gear, wherein a torque is created by the resultant force, and rotating at least one of the first gear or the second gear based on the created torque until first teeth of the first gear mesh with second teeth of the second gear.

A sheet feeder and separator assembly for separating and sequentially feeding individual print media sheets from a stack thereof includes a frame having at least one bearing recess. A removable print media tray is carried by the frame. A separator is connected to the removable print media tray. A pick module assembly is removably connected to the frame adjacent the removable print media tray. The pick module assembly includes a pick roller adjacent the separator to form a nip and at least one flexible bearing is removably received in the at least one bearing recess to removably connect the pick module assembly to the frame.

A fusing roller of the type having a thin resistance heating layer near its surface has a core made of a thermally and electrically insulative material, such as glass, which has a coefficient of thermal expansion comparable to that of the resistance heating layer. The roller can then withstand a high temperature curing process for other layers without separation of the resistance layer from the core.

An image formation device having computer readable instructions that alleviate the necessity of the user to enter the correct page size into the image formation device. The computer readable instructions contain, among other things, a look-up table, or map, of known print media dimensions the image formation device is able to handle. The size of the media loaded into the image formation device is detected and assigned a value according to the look-up table, or map, of the computer readable instructions. The value is compared to the known types of media that are supportable by the printer. These types of media are grouped into predetermined categories according to their respective width dimensions. A determination of whether the image formation device performs a function is made based on the comparison of the converted value to the predetermined group of media.

A surgical apparatus is provided for penetrating body tissue. The apparatus includes a cannula and an obturator configured for insertion into the cannula. The obturator has a body tissue cutting member mounted to a distal portion which is movable between deployed and non-deployed positions. An actuating mechanism is operatively associated with the tissue cutting member and is selectively controllable by a user so as to move the tissue cutting member between the deployed and non-deployed positions independent of the position of the obturator.

An apparatus for transporting media in a printer helps reduce vibration and noise in the printer. The apparatus includes a pair of brackets secured to a printer surface, a shaft, a first portion of the shaft being secured within one of the brackets and a second portion of the shaft being secured within the other bracket, a roller mounted about the shaft for rotation about the shaft, and a pair of vibration dampeners, one vibration dampener being interposed between the first portion of the shaft and the one bracket, and the other vibration dampener being interposed between the second portion of the shaft and the other bracket.

A printer for generating an image on a media sheet has a printer body with a media path extending from a media supply in a downstream direction to a media exit. An output tray and a media ejection mechanism are connected to the printer body adjacent the media exit. The ejection mechanism has a number of drive roller pairs, each of which includes a first roller and a second roller contacting each other at a nip defining a nip plane. The first rollers of the respective roller pairs are coaxial with each other, and the second rollers of the respective roller pairs are coaxial with each other. The nips of the drive roller pairs occupy a common plane, and the drive roller pairs are spaced apart from each other to define a gap. The ejection mechanism includes at least one corrugation roller positioned in the gap, rotatable on a corrugation roller axis, and having a curved surface portion displaced from the nip plane.
摘要:
A media sheet handling system and a method of duplex printing are disclosed wherein a media sheet is imaged with a phase change ink on both sides of the media sheet without smudging or remelting the images and the media sheet is partially exited from the printer into a media output tray and then is drawn back into the printer along a duplex path of travel that automatically reverses the media sheet so that the trailing edge becomes the leading edge during the imaging of the second side of the media sheet. The stiffness of the media sheet facilitates the media sheet moving above and beyond a stationary media path diverter prior to reversing its direction of travel along and passing along the duplex path of travel back to the imaging station.

A blade actuating assembly is provided which permits selective reciprocal movement of a tissue cutting blade positioned at a distal end of an optical trocar assembly from a non-deployed position to a deployed position and back to a non-deployed position. The trocar assembly has an optical obturator which includes a sleeve having a longitudinal bore between a proximal end and a distal end. The longitudinal bore of the sleeve is configured to receive at least a portion of an endoscope or like image transferring system. An objective optical member, such as an optical window is positioned at the distal end of the sleeve and is provided to permit optical images to pass into the longitudinal bore of the sleeve and to permit illumination light to pass to the surgical site.

A method of cleaning a media preheater that is positioned in the media path of a printer is disclosed. The media preheater has a fixed heater and a movable plate array biased toward the heater such that printer media passing between the plate array and the heater is compressed therebetween and heated. The preheater may be positioned upstream of a print head and downstream of a media advancing mechanism in the media path. More than one plate may be provided in the plate array to accommodate non-planarity of the heater or the printing media. The method elevates the temperature of the contact surface of the preheater to a cleaning temperature that is greater than the operating temperature and then passes a chase sheet over the surface to remove contamination from the preheater surface.
