Conventional catch trays receive output from a document production resource such as a printer, copier, scanner and/or the like. Typically, catch trays have ribs that help reduce static between the processed media and the catch tray. In addition, the ribs elevate the processed media, thus making it easier to retrieve the media from the catch tray. Commonly, the ribs are triangular in shape and have a pointed tip onto which the processed media is received.
Conventional catch trays can receive processed media sheets image side down. For such trays, the ribs often scrape and otherwise damage the media images. In addition, a large stack of processed media applies significant pressure to the media sheet on the bottom of the stack which can also cause damage to the media images.
Before the present methods are described, it is to be understood that this invention is not limited to the particular systems, methodologies or protocols described, as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present disclosure which will be limited only by the appended claims.
It must be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural reference unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art. As used herein, the term “comprising” means “including, but not limited to.”
In an embodiment, a catch tray may include a first end configured to connect to a document production resource, a second end and a top surface having a plurality of ribs. A rib may have a first end and a second end. At least one rib may extend from the first end of the catch tray toward the second end of the catch tray. The height of the rib at the first end of the rib may be larger than the height of the rib at the second end of the rib. The rib may include a first curved side portion, a second curved side portion, and a top portion connected to the first curved side portion and the second curved side portion.
In an embodiment, a device for processing print jobs may include a feeder, a tray base configured to interconnect with the feeder and a catch tray configured to interconnect with the tray base. The catch tray may include a first end, a second end and a top surface having a plurality of ribs. At least one rib may extend from the first end of the catch tray toward the second end of the catch tray, and the rib may have a first end and a second end. The height of the rib at the first end of the rib may be larger than the height of the rib at the second end of the rib. The rib may include a first curved side portion, a second curved side portion and a top portion connected to the first curved side portion and the second curved side portion.
Aspects, features, benefits and advantages of the present invention will be apparent with regard to the following description and accompanying drawings, of which:
For purposes of the discussion below, a “document production resource” refers to a printer, a copier, a multifunction machine or system, a xerographic machine or system, or any other type of reproduction apparatus that is capable of printing images on at least a portion of a sheet.
A “sheet” refers to a physical sheet of paper, plastic and/or other suitable substrate for printing images thereon.
A “catch tray” refers to a tray that receives processed media from a document production resource.
A “rib” refers to a protrusion or ridge on a catch tray.
A “job” refers to a logical unit of work that is to be completed for a customer. A job may include one or more print jobs from one or more clients. A production system may include a plurality of jobs.
A “print job” refers to a job processed in a document production system.
In an embodiment, the catch tray 100 may be an offset catch tray. In an embodiment, the catch tray 100 may receive multiple print jobs that are offset from each other in order to distinguish the print jobs. For example, the position of one print job on the catch tray 100 may be offset from the position of another print job on the catch tray so a user may discern where one print job ends and another begins.
In an alternate embodiment, the catch tray 100 may be a static catch tray. A static catch tray may receive print jobs without any offset between them.
In an embodiment, the catch tray 100 may receive media from the document production resource once the media has been processed. The second end 110 of the catch tray 100 may extend outwardly from the document production resource as illustrated by
In an embodiment, the top surface 115 of the catch tray 100 may have a plurality of ribs 120a-N. For example, as illustrated by
In an embodiment, a rib 120a-N may be positioned such that it does not catch the edge of one or more sheets. For example, a rib 120a-N may be positioned on a catch tray 100 such that it does not catch the edge of an 8.5×11-sized sheet, an A4 LEF sheet, an A4 SEF sheet and/or the like.
In an embodiment, a rib 120a-N may extend from the first end 105 of the catch tray 100 toward the second end 110 of the catch tray. In an embodiment, a first end 125 of a rib 120a-N may be located a distance from the first end 105 of the catch tray 100 and a second end 130 of the rib 120a-N may be located a distance from the second end 110 of the catch tray. For example, the first end 125 of a rib 120a-N may be located approximately 65 millimeters from the first end 105 of the catch tray 100, while the second end 130 of the rib 120a-N may be located approximately 29-31 millimeters from the second end 110 of the catch tray. A rib 120a-N may be located at additional and/or alternate distances from the first end 105 and/or the second end 110 of the catch tray 100 within the scope of this disclosure.
In an embodiment, the length of a rib 120a-N may be between approximately 289.0 millimeters and 295.0 millimeters. Additional and/or alternate rib lengths may be used within the scope of this disclosure.
In an embodiment, one or more ribs 120a-N may be a different length than one or more other ribs. For example, if a catch tray 100 has four ribs 120a-N, the middle two ribs may be one length, while the outer two ribs may be another length.
In an embodiment, a rib 120a-N may be integrally formed with the top surface 115 of the catch tray 100. The ribs 120a-N may be raised relative to the top surface 115 of the catch tray 100. In an embodiment, the ribs 120a-N may be fabricated from plastic, metal and/or any other suitable material.
As illustrated by
In an embodiment, the height of a rib 120a-N may be graduated in the direction that the media is received.
In an embodiment, the height of the rib 120a-N may gradually increase toward a second end 130 of the rib 120a-N. For example, the height of the rib 120a-N at the second end 130 may be larger than the height of the rib at the first end 125. In an embodiment, graduated ribs may help minimize image marking on processed media.
It will be appreciated that various of the above-disclosed and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Also that various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
