Document feeder appears broken in my HP officejet 7310
7310 officejet document feeder won't recognize paper: All of a sudden, I put a paper on document feeder and it doesn't recognize that paper is loaded. There is no paper jam. It just says copying 1/1 and then nothing happens! Lifted the document feeder cover up and nothing looks odd. What else can I do?

Sounds like there is something going on with the paper sensor flag that resides in the top cover of the automatic document feeder. Need to make sure it is moving freely. It is spring loaded so it should move freely and spring back in to place. Sounds like your may be sticking in the up position after a few sheets. When the ADF lid is down these sensor flags should go in to holes in the bottom of the ADF. Hope this helps..
please check gear train and confirm no broken one-check of selonid not working in a right way and no foreign object droped inside(like pins).-check of smoth actuation of paper present detector.(in place and movement when you put papers
possible cause is that you have broken the DF door tail that senses the door closed. Check by opening the cover you should see a slit with either a switch in there or a light sensor. Push the switch down using small flat blade screw driver or if light sensor place a folded piece of paper in the gap.
Either one should then recognize that the door is closed.
Hope this can help and if this does work will need to replace the door.
Hi, When you had the doucment feed jam were you able to clean or remove any paper that might be blocking the paper to be scanned? It sounds like there is paper still in the document feeder , I would open the DF and check very closely to make sure no paper is in the way!Good Luck!
