Abstract
A substrate sensing mechanism is provided for use in a printer output bin. The sensing mechanism includes a flag having a shape such that when one or more substrates, which have been removed from the bin, are manually reinserted into the bin, the one or more substrates are directed beneath the flag without causing a substrate feed failure. The flag is also positioned and shaped so as to move to a full bin position when a portion of one or more curled substrates extends to or above a level of the substrate output path immediately adjacent the bin entrance.
Claims6
A media contact member coupled to a printer output bin having an entrance through which printed substrates pass as they move along a printed substrate output path for stacking within the bin, said media contact member comprising a main body portion adapted to be movably coupled to the printer output bin and to extend to the printed substrate output path, said main body portion having first and second side portions, said first side portion facing the bin entrance and said second side portion facing an end of the bin opposite the entrance, said first side portion being shaped such that a substrate entering the bin is directed beneath said main body portion and said second side portion being shaped such that when one or more substrates are manually inserted through an end of the bin opposite the bin entrance, the one or more substrates are directed beneath said main body portion, said first side portion extending to a first level above media contacted by said main body portion and said second side portion extending to a second level above media contacted by said main body portion, said second level being less than said first level, wherein said first side portion and said second side portion converge downwardly to form a hollow interior and wherein said main body portion further includes a section extending across said output path shaped such that a portion of one or more curled substrates moves said main body portion to a full bin position when said portion of one or more curled substrates extends to or above a level of the substrate output path immediately adjacent the bin entrance.
