20100032886 | Composite Substrate Feeding Mechanism - Embodiments described herein include a composite feeding mechanism configured to process one or more jobs using a stack of feeder trays. The composite feeding mechanism can include the stack of feeder trays, a base unit, and a feeder unit. The feeder trays can hold substrate media to satisfy jobs and the base unit can support the stack of feeder trays. The feeder unit can remove the substrate media from a feeder tray located at the top of the stack to satisfy a job requirement. | 02-11-2010 |
20100110508 | PRINTING APPARATUS HAVING COMMON SCANNING AND PRINTING FEED PATH - Disclosed are an apparatus including a media feed tray holding media to be printed, a media printing feed path along which the media to be printed are fed from the media feed tray, a scanner feed tray holding media to be scanned, and a scanner feed path along which the media to be scanned are fed from the scanner feed tray, wherein the scanner feed path overlaps with at least a portion of the media printing feed path, and a corresponding method. | 05-06-2010 |
20110309567 | COMPOSITE SUBSTRATE FEEDING MECHANISM - Embodiments described herein include a composite feeding mechanism configured to process one or more jobs using a stack of feeder trays. The composite feeding mechanism can include the stack of feeder trays, a base unit, and a feeder unit. The feeder trays can hold substrate media to satisfy jobs and the base unit can support the stack of feeder trays. The feeder unit can remove the substrate media from a feeder tray located at the top of the stack to satisfy a job requirement. | 12-22-2011 |
