It is to be understood that other examples may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure.
- As illustrated in the example of
FIGS. 1A and 1B , the present disclosure provides an automatic document feeder (ADF) 10. In one implementation, ADF 10 includes amedia path 12 toroute media 2 throughADF 10, andautomated media trays 14 to supplymedia 2 tomedia path 12 and receivemedia 2 frommedia path 12, as represented byarrows 4. In examples,automated media trays 14 include aninput tray 141 to supplymedia 2 tomedia path 12, and anoutput tray 142 to receivemedia 2 frommedia path 12. - In examples,
automated media trays 14, includinginput tray 141 andoutput tray 142, are to be positioned based on a presence of auser 20 atADF 10. For example, as illustrated in the example ofFIG. 1A , without the presence ofuser 20 atADF 10,automated media trays 14 are in a closed positon, and, as illustrated in the example ofFIG. 1B , with the presence ofuser 20 at ADF 10,automated media trays 14 are in an open positon. As such, as illustrated in the example ofFIG. 1A , without the presence ofuser 20 atADF 10,automated media trays 14 are non-communicated withmedia path 12, and, as illustrated in the example ofFIG. 1B , with the presence ofuser 20 atADF 10,automated media trays 14 are communicated withmedia path 12. In one implementation, ADF 10 includes asensor 16 to sense the presence ofuser 20 atADF 10, and provide input to control the position ofautomated media trays 14. - As disclosed herein, an automatic document feeder, such as
ADF 10, may be used to automatically transport media (one sheet or multiple sheets sequentially) along a media path, such asmedia path 12, from an input tray, as an example of anautomated media tray 14, to a scanning or imaging position, and then to an output tray, as another example of anautomated media tray 14. At the scanning or imaging position, the media may be scanned or imaged for copying, scanning, faxing, displaying on a monitor, or other processing. In examples, ADF 10 may be part of a printer, a scanner, a photocopier, a fax machine, or a multi-function or all-in-one device providing printing, scanning, copying, and/or faxing capabilities. -
FIG. 2 illustrates an example of an inkjet printing system.Inkjet printing system 100 includes aprinthead assembly 102, as an example of a fluid ejection assembly, a fluid (e.g., ink)supply assembly 104, amounting assembly 106, amedia transport assembly 108, anelectronic controller 110, and apower supply 112 that provides power to electrical components ofinkjet printing system 100.Printhead assembly 102 includes aprinthead die 114, as an example of a fluid ejection die or fluid ejection device, that ejects drops of fluid through a plurality of orifices ornozzles 116 toward aprint media 118 so as to print onprint media 118. -
Print media 118 can be any type of suitable sheet or roll material, such as paper, card stock, transparencies, Mylar, and the like, and may include rigid or semi-rigid material, such as cardboard or other panels.Nozzles 116 are arranged in columns or arrays such that properly sequenced ejection of fluid fromnozzles 116 causes characters, symbols, and/or other graphics or images to be printed onprint media 118 asprinthead assembly 102 andprint media 118 are moved relative to each other. -
Fluid supply assembly 104 supplies fluid toprinthead assembly 102 and, in one example, includes areservoir 120 for storing fluid such that fluid flows fromreservoir 120 toprinthead assembly 102. In one example,printhead assembly 102 andfluid supply assembly 104 are housed together in an inkjet cartridge or pen. In another example,fluid supply assembly 104 is separate fromprinthead assembly 102 and supplies fluid toprinthead assembly 102 through an interface connection, such as a supply tube. -
Mounting assembly 106positions printhead assembly 102 relative tomedia transport assembly 108, andmedia transport assembly 108positions print media 118 relative toprinthead assembly 102. Thus, aprint zone 122 is defined adjacent tonozzles 116 in an area betweenprinthead assembly 102 andprint media 118. In one example,printhead assembly 102 is a scanning type printhead assembly. As such,mounting assembly 106 includes a carriage for movingprinthead assembly 102 relative tomedia transport assembly 108 to scanprint media 118. In another example,printhead assembly 102 is a non-scanning type printhead assembly. As such, mountingassembly 106 fixesprinthead assembly 102 at a prescribed position relative tomedia transport assembly 108. Thus,media transport assembly 108positions print media 118 relative toprinthead assembly 102. -
Electronic controller 110 includes a processor, firmware, software, memory components including volatile and non-volatile memory components, and other printer electronics for communicating with and controllingprinthead assembly 102,mounting assembly 106, andmedia transport assembly 108.Electronic controller 110 receivesdata 124 from a host system, such as a computer, and temporarily storesdata 124 in a memory.Data 124 is sent toinkjet printing system 100 along an electronic, infrared, optical, or other information transfer path.Data 124 represents, for example, a document and/or file to be printed. As such,data 124 forms a print job forinkjet printing system 100 and includes print job commands and/or command parameters. - In one example,
electronic controller 110 controlsprinthead assembly 102 for ejection of fluid drops fromnozzles 116. Thus,electronic controller 110 defines a pattern of ejected fluid drops which form characters, symbols, and/or other graphics or images onprint media 118. The pattern of ejected fluid drops is determined by the print job commands and/or command parameters. -
Printhead assembly 102 includes one (i.e., a single)printhead die 114 or more than one (i.e., multiple)printhead die 114. In one example,printhead assembly 102 is a wide-array or multi-head printhead assembly. In one implementation of a wide-array assembly,printhead assembly 102 includes a carrier that carries a plurality ofprinthead dies 114, provides electrical communication betweenprinthead dies 114 andelectronic controller 110, and provides fluidic communication betweenprinthead dies 114 andfluid supply assembly 104. - In one example,
inkjet printing system 100 is a drop-on-demand thermal inkjet printing system whereinprinthead assembly 102 includes a thermal inkjet (TIJ) printhead that implements a thermal resistor as a drop ejecting element to vaporize fluid in a fluid chamber and create bubbles that force fluid drops out ofnozzles 116. In another example,inkjet printing system 100 is a drop-on-demand piezoelectric inkjet printing system whereinprinthead assembly 102 includes a piezoelectric inkjet (PIJ) printhead that implements a piezoelectric actuator as a drop ejecting element to generate pressure pulses that force fluid drops out ofnozzles 116. - In examples,
inkjet printing system 100 includes an automatic document feeder (ADF) 130, as an example ofADF 10, and animage reader 126 such that ADF 130 automatically transportsmedia 128 along amedia path 132, as an example ofmedia path 12, to and/orpast image reader 126. As such,image reader 126 may acquire and/or generate an image of a side or surface ofmedia 128. - In one implementation, ADF 130 includes
automated media trays 134, as an example ofautomated media trays 14, to supportmedia 128 for input to media path 132 (e.g., an input tray) and to receivemedia 128 as output from media path 132 (e.g., an output tray). In examples,automated media trays 134 may be automatically positioned (for example, closed or opened, stowed or deployed, covered or uncovered, concealed or revealed, retracted or extended, non-communicated or communicated, accessible or inaccessible) based on a presence of a user ofinkjet printing system 100, including based on a presence of a user atADF 130. - In examples, a presence of a user is determined by a
sensor 136. In one implementation,sensor 136 is communicated withelectronic controller 110 andelectronic controller 110 is communicated with ADF 130, includingautomated media trays 134. As such,electronic controller 110 controls a position ofautomated media trays 134 based on a presence of a user ofinkjet printing system 100, including based on a presence of a user atADF 130, as determined bysensor 136. -
FIGS. 3A and 3B are perspective views illustrating an example of an automatic document feeder (ADF) 200, as an example ofADF 10, including automatedmedia trays 210, as an example ofautomated media trays 14, in a closed position and an open position, respectively, andFIGS. 4A and 4B are cross-sectional views illustrating an example ofADF 200 withautomated media trays 210 in a closed position and an open position, respectively. In one implementation, as disclosed herein, automatedmedia trays 210 may be automatically positioned (e.g., moved between a first position and a second position) based on a position of a user, for example,user 220, as an example ofuser 20, relative toADF 200 including, more specifically, based on a presence of a user, for example,user 220, atADF 200. In examples, automatedmedia trays 210 may be automatically positioned based on a proximity of a user, for example,user 220, being within a predetermined distance ofADF 200. - As illustrated in the example of
FIGS. 3A and 3B, 4A and 4B ,ADF 200 includes ahousing 202, automatedmedia trays 210 supported byhousing 202, and amedia path 204, as an example ofmedia path 12, withinhousing 202. In examples,media path 204 includes a variety of guides, rollers, wheels, etc. to achieve handling and routing of media within and/or throughADF 200, as disclosed herein. - In one example, automated
media trays 210 include aninput tray 211 and anoutput tray 212 such thatinput tray 211 supports and supplies media for input toADF 200, andoutput tray 212 receives and supports media as output fromADF 200. As illustrated in the example ofFIGS. 3B and 4B , in an open position, as further described below,input tray 211 andoutput tray 212 are positioned such thatinput tray 211 communicates with one end of media path 204 (i.e., an input end), andoutput tray 212 communicates with an opposite end of media path 204 (i.e., an output end). As such, media may be routed frominput tray 211 tooutput tray 212 alongmedia path 204, as represented by broken line arrows 205 (FIG. 4B ). - As disclosed herein, automated
media trays 210, including bothinput tray 211 andoutput tray 212, may be automatically positioned (e.g., oriented, arranged, configured, operated, actuated) to selectively communicate withmedia path 204 or provide access tomedia path 204. For example, as illustrated in the examples ofFIGS. 3A and 4A , automatedmedia trays 210, including bothinput tray 211 andoutput tray 212, are positioned so as not to communicate with or provide access tomedia path 204. More specifically, in the position ofFIGS. 3A and 4A , automatedmedia trays 210 are in a closed, stowed, covered, concealed, or retracted position (collectively referred to herein as a “closed position” for simplicity) such thatautomated media trays 210 are not communicated with media path 204 (i.e., are non-communicated or uncommunicated with media path 204). In addition, as illustrated in the examples ofFIGS. 3B and 4B , automatedmedia trays 210, including bothinput tray 211 andoutput tray 212, are positioned to communicate with or provide access tomedia path 204. More specifically, in the position ofFIGS. 3B and 4B , automatedmedia trays 210 are in an open, deployed, uncovered, revealed, or extended position (collectively referred to herein as an “open position” for simplicity) such thatautomated media trays 210 are communicated withmedia path 204. - In one implementation, as disclosed herein, a position of
automated media trays 210 including, more specifically, a position ofinput tray 211 and a position ofoutput tray 212, may be established based on a presence of a user, for example,user 220, atADF 200. More specifically, without a presence of a user atADF 200, or with an absence of a user atADF 200, automatedmedia trays 210 may be in a closed position, as illustrated, for example, inFIGS. 3A and 4A . As such, automatedmedia trays 210 do not communicate withmedia path 204, andADF 200 is not available for use. However, with a presence of a user, for example,user 220, atADF 200, automatedmedia trays 210 may be in an open position, as illustrated, for example, inFIGS. 3B and 4B . As such, automatedmedia trays 210 communicate withmedia path 204, andADF 200 is available for use. - In one implementation, a presence (or absence) of a user at
ADF 200 is based on a proximity of a user toADF 200. More specifically, in examples, when a user is not within a proximity of ADF 200 (i.e., the proximity of the user is not less than a threshold), automatedmedia trays 210 may be in a closed position, for example, automatically moved to or changed to a closed position, as illustrated, for example, inFIGS. 3A and 4A . And, in examples, when a user, for example,user 220, is within a proximity of ADF 200 (i.e., the proximity of the user is less than a threshold), automatedmedia trays 210 may be in an open position, for example, automatically moved to or changed to an open position, as illustrated, for example, inFIGS. 3B and 4B . - In one example, a proximity of a user to
ADF 200 may be determined by or based on a reading of asensor 206, as an example ofsensor 136. In one implementation,sensor 206 is supported by or mounted onhousing 202 ofADF 200. In examples,sensor 206 is an optical or laser-based sensor such as a time-of-flight (TOF) laser sensor, including 2D or 3D laser scanning, such as LIDAR, or other scanning, sensing and/or detection capability. - In one implementation,
sensor 206 is a proximity sensor and measures or determines a distance of an individual, for example,user 220, fromADF 200. In examples, if an individual is within a predetermined distance ofADF 200, as measured or determined, for example, bysensor 206, a presence of an individual atADF 200 is established (such thatautomated media trays 210 are in or automatically moved to or changed to the open position). However, if an individual is not within a predetermined distance ofADF 200, as measured or determined, for example, bysensor 206, a presence of an individual atADF 200 is not established and, correspondingly, an absence of an individual atADF 200 is established (such thatautomated media trays 210 are in or automatically moved to or changed to the closed position). - For example, when a user is not at or is not approaching ADF 200 (i.e., is not within a predetermined distance of ADF 200), automated
media trays 210 are in the closed position (e.g.,FIGS. 3A and 4A ). However, when a user, for example,user 220, is at or approaches ADF 200 (i.e., is within a predetermined distance of ADF 200) automatedmedia trays 210 are automatically moved to or changed to the open position (e.g.,FIGS. 3B and 4B ). As such, the user may useADF 200. Thereafter, when the user leaves or walks away from ADF 200 (and, therefore, is not within a predetermined distance of ADF 200), automatedmedia trays 210 are automatically moved to or changed to the closed position (e.g.,FIGS. 3A and 4A ). - In one implementation,
sensor 206 operates as a verification or authentication sensor for controlled access toADF 200. Authorization to useADF 200 may be established, for example, by a user credential, such as a badge or access card (e.g., employee badge or access card with RFID, bar code, magstripe, etc.) or a code (e.g., unique pin). For example, if a user is at or approaches ADF 200 (i.e., is within a predetermined distance of ADF 200), but is not authorized to useADF 200, automatedmedia trays 210 are in the closed position (e.g.,FIGS. 3A and 4A ). However, if a user is at or approaches ADF 200 (i.e., is within a predetermined distance of ADF 200), and is authorized to useADF 200, automatedmedia trays 210 are automatically moved to or changed to the open position (e.g.,FIGS. 3B and 4B ). As such, the user may useADF 200. Thereafter, when the user leaves or walks away from ADF 200 (and, therefore, is not within a predetermined distance of ADF 200), automatedmedia trays 210 are automatically moved to or changed to the closed position (e.g.,FIGS. 3A and 4A ). - In one implementation, a presence of a user at
ADF 200 is based on physical interaction withADF 200 by a user. In one example, when a user interacts with a control panel of ADF 200 (or a control panel of a printer including ADF 200), automatedmedia trays 210 may be in an open position, for example, automatically moved to or changed to an open position, as illustrated, for example, inFIGS. 3B and 4B . - In one example, the closed position of
automated media trays 210 and the open position ofautomated media trays 210 represent different operational modes ofADF 200. More specifically, in one implementation, a closed position ofautomated media trays 210 represents a standby mode ofADF 200, and an open position ofautomated media trays 210 represents a ready or use mode ofADF 200. - In one implementation, automated
media trays 210, includinginput tray 211 andoutput tray 212, are pivoted relative tohousing 202 to establish the open position and the closed position. More specifically, automatedmedia trays 210 are pivotally mounted in or pivotally supported byhousing 202. In one example,input tray 211 is pivotally mounted or pivotally supported about anaxis 213, andoutput tray 212 is pivotally mounted or pivotally supported about anaxis 214. As such, between the closed position ofFIGS. 3A and 4A and the open position ofFIGS. 3B and 4B ,input tray 211 is pivoted aboutaxis 213 andoutput tray 212 is pivoted aboutaxis 214. - In examples,
ADF 200 includes a drive system 216 (FIGS. 4A and 4B ) to moveinput tray 211 andoutput tray 212 and establish the open position and the closed position. In implementations,drive system 216 may include, for example, a motor, solenoid or other mechanism and associated gears, guides or other components operatively connected to or coupled withinput tray 211 andoutput tray 212 to move or changeinput tray 211 andoutput tray 212, collectively or individually, and establish the open position and the closed position of each. -
FIG. 5 is a flow diagram illustrating an example of amethod 500 of operating an automatic document feeder, such asautomatic document feeder FIGS. 1A and 1B ,FIG. 2 ,FIGS. 3A and 3B, 4A and 4B , respectively. - At 502,
method 500 includes sensing a presence or an absence of a user at the automatic document feeder, such asuser automatic document feeder FIGS. 1A and 1B ,FIGS. 3A and 3B, 4A and 4B , respectively. - At 504,
method 500 includes, with sensing the presence of the user at the automatic document feeder, establishing an open position of both an input tray and an output tray of the automatic document feeder, such as an open position ofinput tray output tray automatic document feeder FIGS. 1A and 1B ,FIGS. 3A and 3B, 4A and 4B . - And, at 506,
method 500 includes, with sensing the absence of the user at the automatic document feeder, establishing a closed position of both the input tray and the output tray of the automatic document feeder, such as a closed position ofinput tray output tray automatic document feeder FIGS. 1A and 1B ,FIGS. 3A and 3B, 4A and 4B . - In one example, establishing the open position of both the input tray and the output tray at 504, includes communicating both the input tray and the output tray with a media path of the automatic document feeder, such as communicating
input tray output tray media path automatic document feeder FIGS. 1A and 1B ,FIGS. 3A and 3B, 4A and 4B , and establishing the closed position of both the input tray and the output tray at 506, includes non-communicating both the input tray and the output tray with the media path of the automatic document feeder, such asnon-communicating input tray output tray media path automatic document feeder FIGS. 1A and 1B ,FIGS. 3A and 3B, 4A and 4B . In one example, sensing the presence or the absence of the user at the automatic document feeder at 502, includes sensing a proximity of the user to the automatic document feeder, such as sensing the presence or the absence ofuser 20 atautomatic document feeder FIGS. 1A and 1B ,FIGS. 3A and 3B, 4A and 4B , respectively. As disclosed herein, an automatic document feeder and method of operating an automatic document feeder includes automated opening and closing of media trays of the automatic document feeder, including automated opening and closing of an input tray and an output tray of the automatic document feeder, based on a presence or an absence of a user at the automatic document feeder. Automated opening and closing of media trays of the automatic document feeder, as disclosed herein, may improve user experience with the automatic document feeder, as the user will not have to manually open and/or close the media trays. When the automatic document feeder is not in use, automated closing of media trays of the automatic document feeder, as disclosed herein, may improve the aesthetic appearance of the automatic document feeder by providing a more “sleek” or “clean” visual appearance to the automatic document feeder. In addition, automated closing of media trays of the automatic document feeder when the automatic document feeder is not in use, may help to limit damage to the media trays, as the media trays (or portions thereof) may not protrude or extend from the automatic document feeder. Furthermore, automated opening and closing of media trays of the automatic document feeder, as disclosed herein, may be used to control access to the automatic document feeder (e.g., limit use of the automatic document feeder to authorized individuals). - Although specific examples have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that a variety of alternate and/or equivalent implementations may be substituted for the specific examples shown and described without departing from the scope of the present disclosure. This application is intended to cover any adaptations or variations of the specific examples discussed herein.
