HP Scanjet N8420 - paper feed stopped working

Just out of the blue one day, that my HP Scanjet N8420 has ceased to recognize the document feeder.  I put documents to be analyzed and it is as if she does not yet recognize in there, there is paper.  I push the right buttons to the tray extra paper.  It's just the noise as it does when you use the flat bed scanner and then does nothing.  I've uninstalled and reinstalled the drivers, and that did nothing.  My one year warranty is in place and the online HP chat people do help me no more.  Can you help me?

adminkim01,

Here is some information on the manual which can be useful.

The ADF cover cannot be locked. Open the ADF cover and then close it by pressing firmly.

A problem with the hardware ADF may exist. Use the following procedures to test the ADF:

  • Unplug the USB cable and the power cable from the scanner. Check that the power cable is still connected to the power source.
  • Make sure that the cable is connected to the accessory port scan and that the ADF has at least two pieces of paper in the input tray.
  • Reconnect the power cable to the scanner and then turn on the scanner.
  • Try to scan another page through the ADF.
  • If the ADF doesn't feed paper, contact HP customer care.

  • Automatic document feeder stop working on printer HP M1536dnf MFP

    Hello.  The automatic of the document (BAA) on my all in one work suddenly quitting coppier.  I cleaned but still nothing.  When you set up a sheet of paper in the tray and it depresses the lever on the power head, he normally had a message like 'paper' on the LCD display.  Now, nothing.  I thought that the driver's head may have failed so I replaced it with a spare that I had but this diddnt help either.  I'm not sure why the ADF will not work, but it turns out quite invonvieiant for my work. If anyone has had this problem and if so, were you able to fix?  Thanks in advance.

    Hey @MarioFleecy,

    If the NVRAM reset on your product could not solve the problem with your ADF, then the next step would be to maintain the product that we have exhausted all the troubleshooting steps.

    I would recommend calling HP support and inform the agent of all the steps that we've come for troubleshooting. When you do that, you will be able to discuss what alternative options are available.

    HP Technical Support can be reached at the: 800-474-6836.

  • Some RSS STREAMS have stopped working.

    When I took the last update for firefox some of my favorite RSS feeds direct have stopped working

  • Time capsule has stopped working

    Time capsule has stopped working. No orange or green light. Food is the device. Is there a fuse that might be blown? Reset it would bring to life?  Is it possible to get the backup data stored on it?

    Is there a fuse that might be blown?

    Sorry, but no.

    Reset it would bring to life?

    No, unfortunately it wouldn't be possible to reset the time Capsule if it will feed at all.

    Is it possible to get the backup data stored on it?

    Open the Capsule and remove the hard drive. Place the disk into a USB to SATA cart and which connect to your Mac.  Here, I'm assuming that the Time Capsule is not yet covered by warranty or the AppleCare, as it opens the warranty, if it is still covered.

    If you could post back with the model number of the Capsule of time... it is on the lower part of the device, probably embedded in the foam pad base, and begins with an 'A' followed by four numbers... we may have some additional information or advice for you depending on the model you have.

  • Since the FF13 update news FEED stopped loading/updating!

    Had heard a report on it and I had the same problem immediately after updating to the latest version.

    I have about 50 live bookmarks on my bookmarks bar and they all stopped working. They charge not even manually - they don't show all the titles: empty set as if they are all dead.

    Needless to say that it's a significant pain in the neck and if all goes well, there a solution or at least a workaround...

    Hello, are you using addons that provide or extend the functionality of the live bookmarks? because firefox 13 changed the way it handles rss feeds in order to optimize performance. test if it works correctly when you run firefox in safe mode - if so, please try to research if there is an update availble for these extensions, or disable them at the moment.
