| 20100014885 | System for Creating a Condition of Substantial Thermal Consistency Between Multiple Printer Cartridges - A system for creating a condition of substantial thermal consistency between multiple printer cartridges includes a frame defining a cavity for supporting the multiple cartridges spaced apart from one another and a plurality of components mounted to the frame in flow communication with one another and with the cavity via the frame. The plurality of components coact with one another and with the frame to generate, regulate and distribute an intake flow of cooling air from the frame into multiple inflows of cooling air along different spaced apart paths at different velocities through the cavity and between the spaced apart multiple cartridges for causing transformation of the multiple inflows of cooling air into multiple outflows of heated air by contact with the multiple cartridges and to exhaust the multiple outflows of heated air from the cavity and frame. | 01-21-2010 |
| 20100038845 | Spring-Assisted Print Media Feeder Apparatus - A print media feeder apparatus suitable for use in an image-forming device is provided. The apparatus comprises an elevator tray holding a stack of print media connected to a housing by a transmission system. The housing comprises a hoist drum that is connected to one end of a shaft for connecting the housing to the transmission system. A spring enclosure encasing a spring is fixed on the other end of the shaft. The load of print media is transmitted to the hoist drum, from which it is further transmitted to the spring through the shaft. This results in the displacement of the spring and a corresponding vertical movement of the elevator tray to position the print media at the desired feeding level. | 02-18-2010 |
| 20100133744 | Media Sheet Guide Device and Method for Maintaining Proper Sheet Alignment in an Image Forming Machine - A media sheet guide device for maintaining proper sheet alignment in an image forming machine includes a body extending between spaced apart reference edges of respective upstream and downstream media alignment mechanisms and a face on the body defining a path along which a sheet moves lengthwise from the upstream reference edge to the downstream reference edge. The face has a section extending widthwise and defining a portion of the path about which the sheet bends widthwise as the sheet moves lengthwise along the path portion. The face section has first and second segments differing in curvature for applying a differential drag widthwise across the sheet causing a rotation of the sheet sufficiently to displace a leading end of the sheet away from the downstream reference edge to thereby ensure that a leading corner of the sheet can enter into the downstream reference edge without jamming against an entry end thereof. | 06-03-2010 |
| 20110042545 | Anti-Tip Stability System Integral to an Imaging Apparatus - An imaging apparatus having a printer frame, a media tray frame module disposed below the printer frame, and an anti-tip stability system including two alignment posts mounted substantially diagonally on the media tray frame module. The alignment posts have first surfaces and second surfaces where each second surface makes an acute angle ranging from about 10 degrees to about 20 degrees with a horizontal plane. The alignment posts provide anti-tip stability to the imaging apparatus by engaging with the printer frame when the printer frame is tilted at a first contact angle with respect to the alignment posts due to the application of an external force. The alignment posts also facilitate relatively easy separation of the printer frame from the media tray frame module. | 02-24-2011 |
