Photosmart HP 7520: Scan lost PC connection

My HP Pavilion is connected to my 2.4 Ghz wireless network, as is my printer.  When you try a scan PC for my printer, I see the message "no computer."  This just started a few days ago. If I scan to email, it works fine. The printer, I reset the IP address and the password.  The computer prints to the printer via the wireless network. In addition, a laptop in another room remotely connects and prints well. I ran two times printing and scanning doctor.  Both times he concludes that the connection is good. Yet, no scanning of the printer.  The box in the toolbar at the bottom of the PC continues to say "Scan of the computer is currently unavailable.  From there I try enable and check the autostart box, but no change. I also downloaded the latest version of the software updated 12/15 no change. However, I found that if I use the HP Scan application on my PC now I have added to my office, it works very well (to the PC).  It's a little more "awkward", but it does the job. I'd rather eat the scan from the printer.  It was quicker and easier. Does anyone know why the printer is unable to 'see' the PC while it is connected to the network and all the functions the scanning started work on PC?

Hi @Javaunoand welcome to the Forums of HP, as you know it is a good place to ask for assistance from members of the community! I'd love to help you with your Photosmart 7520. If I understand your description you can scan when you start scanning from the printer software, but when you try to scan from the front of the printer, the analysis did not make for a lack of connectivity.

Be able to scan from the computer leads me to believe that the connectivity is not the root cause of the problem. However, I found something that might help.

This document contains information on the possible causes of an interruption of the connection wireless, tips to avoid the question, tips to maintain a connection and troubleshooting to help you re-establish the connection Wireless on your printer; The printer keeps Wi-Fi connection.

In addition to the solutions proposed in the document and you've probably already tried, please make sure that the printer is connected directly to a wall outlet, not a surge protector / power bar. Questions when it is connected to an uninterruptible power supply/Strip/surge protector power

In this document, you will see:

Questions or problems may arise when a HP LaserJet printer is connected to a UPS (UPS), a power strip or a surge protector

↑ This is not limited to the Laserjet printers.

It is also good if you already haven't, to be sure the printer firmware is up to date. This Firmware update improves and addresses the following issues:

  • Update the firmware of the modem FAX to avoid false failures FAX Test
  • Solves problems in networking that can cause the printer not responding
  • Improves the reliability of the cloud print
  • Improves the reliability of printing using HP ePrint and printable applications
  • Improves the reliability of the printer, automatic updates
  • Improves support for AirPrint™
  • Corrects the minor defects

Update firmware to improve the functionality and performance.

Disabling UPnP can be worth it too if the problem at this point. Follow the steps below to disable UPnP in the EWS printers,

1 type the printers assigned to IP address in the Internet Explorer address bar. (you can get this report you would have printed everything by following the steps described in the document that I posted above)

2. click on the network at the top tab

3. Select the option of networking on the left

4. click the UPnP option on the left

5 Select the option 'Disable UPnP'

6. click on 'apply '.

And finally, I would like to disable IPv6 on the printer. This setting can sometimes cause problems. Follow the instructions below to disable IPv6

  • On the front panel of the printer, press the wireless icon, this is the second of the four icons on the top.
  • Navigate through the Wireless advanced settings menu and go to the IPv6
  • Disable IPv6

  • Photosmart HP 7520: scan hp connects to the scanner

    I have a new MacBook Pro that came with installed Yosemite.  I think that HP Scan frequently does not connect to my scanner HP Photosmart 7529 using my wifi.  I get an error indicating that the scanner... is currently unavailable.  I called the service of HP and their only solution was to do the following in order: 1. turn off the router, 2 disable the 7520, 3 put the router 4 switch 7520.  Now, it works but it happens regularly and frankly is quite a pain and I'm sure is not how it is supposed to work.

    The scanner worked well with my previous MacBook Pro (OSX Lion).  The scanner also works through preferences, but that method has very limited functionality.  How can I get this problem?

    Hello

    For the last few days I am facing problems of scan to e-mail function. It gives me an error - "failed to connect to Web Services. "Confirm access to the internet and try again. I checked access to internet, is turned off and turned back on, but everything is fine, except that scanning to e-mail still does not work.

    I also tried the suggestion of manual entry of the DNS server in the DNS address configuration, but it does not work.

    Kindly help.

    Hello @alok7,

    Welcome to the HP community!

    I understand that you have a problem with scanning to E-mail app on e-all-in-one printer, HP Photosmart 7520. I'd love to help you with this.

    Here are the steps I suggest to try everything first:

    Network Power Reset:

    We'll leave the router and unplug the power cable (NOTE: do not reset the router.), and then do the same with the printer and shut down the computer. After a minute, plug in the router, wait to fully turn on, then plug the printer back in and wait for the wireless light become solid. Once the router and the printer are on, go ahead and re - turn on the computer. This will refresh the network connection.

    Restore the default settings of the network and reconnect:

    1. on the front panel of the printer, press your up wireless icon

    2. Select settings.

    3. Select restore default network settings.

    4 turn on your printer.

    5. once it is initialized to save, press the wireless icon again.

    6. Select settings.

    7. Select Wireless Assistant , and then follow the prompts to enter the details of your wireless network.

    8. try to activate the web services again.

    Configure a manual DNS for your printer:

    You mentioned that you have already tried defining a manual DNS for your printer, DNS that you used. If you have not already tried so, I suggest to use primary like DNS 8.8.8.8 and 8.8.4.4 as the secondary DNS.

    If your web services connected, even if scanning to email does not work, you may need to reset the web services on the device.

    NOTE: Reset web services clears the custom email ePrint you have configured on your printer. Please be aware that if you have a personalized email ePrint, after doing this, you will need to configure again and will not be able to use the same address.

    1. press the Web Services button on the front panel.
    2. tap on settings.
    3. pressremove web services"and confirm deletion.
    This will bring you to the homepage.
    4. press on the icon Web Services , once again on the printer and go through the installation process.

    5. once the web service has been activated again, try to configure your scan to E-mail

    Please reply to let me know if these measures have helped to solve your problem.

  • Photosmart HP 7520 - loss of WiFi connection

    Hello

    Have recently purchased a 7520 - works well however when the printer goes to sleep I can't access them from my iPad or iPhone using AirPrint. I have to turn on/off the wireless connection to use it, that beats the point of having a wireless printer. Any suggestions please. Thank you.

    Dave,

    Excellent.

    Wireless live - while not exactly what I would expect; a hotfix is a patch.

    I tested my setup: I had a similar problem (maybe) when I got the printer installed only on Windows 8: here, not there, print, sometimes not able to print, errors of various types.  I could never install the update of the firmware: I need a cable and the wireless installation / update has failed repeatedly.  It is difficult to say that the question was 'same' like yours; our very different network configurations.

    Interestingly, installing the printer on a system running Windows Pro 8.1 (yesterday) did apparently happier printer - no more disconnections, unspecified errors or other problems.  No listed in the printer drivers firmware update; my new USB printer cable was a waste of money.  The smile.

    I was reminded by an Expert from HP (who works for HP) that to remove the cartridges from the printer CONFIGURATION after initial installation could backfire against - cartridges are very prone to drying out.  I got my cartridges SETUP as best as I can (with tops Orange and double sealed heavy bags)-I have them verify maybe in a few months to see how they are doing.

    Happy computing!

    Click on the star of congratulations !

    It's a nice way of saying 'Thank you' for help.

    Although I strive to reflect best practices of HP, I do not work for HP.

  • Photosmart B109 n - z: lost wifi

    My Photosmart B109 n - z lost wifi connectivity. I had a loss of power after what my router was not working properly. The router now, OK but I can't see the printer either from my laptop Windows 7 or my HP smartphone application. All other devices are connected OK.

    Chris46,

    You can reinstall the software of full functionality for the printer.

    HP Photosmart Wireless all-in - One Printer - B109n drivers

    After installing the software, check if the category updates apply to your situation.

    If you have already reinstalled the printer software, you can try to restart everything, including the router.

    If this does not work, you can try using the Web integrated (Embedded Web Server) server to reset / double check network settings in the configuration of the printer.  You can use your browser preferred for it - Internet Explorer or Firefox, both work well with EWS.

  • Photosmart 7520 I lost a scan wireless

    I was scanning documents with the PS 7520 and Adobe Pro XI, when, for no apparent reason, I lost the ability to analyze.  I received the following error message - "error while interacting with the scanner: the selected scanner was not found."  The printer/scanner was successfully created in Windows and the device appears under the selected name.  I was able to regain the functionality of scanning by restarting and update the printer IP address.  Printing documents wirelessly seems to be affected.

    My question is... what happened, why, and what should I do if this problem occurs again?

    Brian

    only you can suggest to read my post here:

    http://h30434.www3.HP.com/T5/printer-all-in-one-software-drivers/7520-e-firmware-update-amp-intermittent-Wireless-WiFi/TD-p/3346431

    If you search this forum, you will find a lot of posts on the 7520 with intermittent wireless connectivity on digitization, etc..

    suggest that you CALL the HP TECHNICAL support and start a business.

    If your printer is new, in the short term, you should be able to return the printer to the store for a refund...

    However, long-term, to the least, having an open case can ensure a certain level of protection for yourself where it continues to be (and probably will)...

    so you have a capacity at the request of HP to deliver a guarantee of Exchange or a refund.

  • Photosmart 7520: Photosmart 7520 has lost its wireless connection

    Our photosmart 7520 used to print beautifully two laptops, but today it stopped printing at all and seems to have lost its connection to the internet.

    I tried to remove it from my system preferences, to reset, and when I tried to add it, it was no longer on the list of available printers.

    Hello @cornylouise!

    Thanks for posting on the HP Forums!

    I would be happy to provide you with assistance on the Photosmart 7520 and the problem of communication between 2 laptops.  If the printer is no longer being found by computers, then you can by looking at a slight problem of Wi - Fi.  The first thing I would suggest is the cycle of power cables to the printer and the router by unplugging the power for 20 seconds.  Once the devices back on then see if you can add the printer to laptop computers.

    If you are unable to find the printer then I suggest to restore the default settings of network on the printer and it reconnect to the wireless network.

    To restore the default settings of the network printer:

    1. To press the Wi - Fi icon at the top of the touch screen to printer
    2. Tap Settings
    3. Tap on restore default network settings and confirm

    To run the Wireless Setup Wizard:

    1. Icon press the Wi - Fi at the top left of the screen touchscreen printer
    2. Tap Settings
    3. Press wireless configuration wizard
    4. Select your network
    5. Enter the password and confirm it
    6. Check if the computer can find the printer again

    If please, after back and let me know how it goes!

  • Photosmart 7520: Photosmart 7520 Scan to Email problem

    Hello

    I have the same problem as almost all the other posts in this forum. I can perform all functions with my Photosmart HP 7520, print from my Mobile / Tablet / PC, Wi - Fi all the Apps front panel, connect to the printer via IP fixed, applications via ePrintCenter etc... Until recently, I could also do a "Scan to Email" but which has suddenly stopped working to fail "unable to connect to Web Services.  Confirm access to the Internet and try again. "I tried all the previous suggestions including cycling the power on my router then the printer, all with no success. As mentioned the only funtion not working is "Scan to Email". I understand there is a 'special reset process' that is sent by electronic mail private users with this specific problem. Could you please make this available.

    Thanks in advance...

    Hi Shoe59,

    I finally got the work of Scan-to-Email service.

    I ended up removing the "Web Services" - via the printer-> Web Services-> settings Menu-> remove Web Services. Immediately after I went through the same steps of menu and "enabled web services" again (I think that something has been downloaded to the printer) and a page is printed with an activation code where you need to connect to your account connection HP and basically setup your account to e-mail printer as again from scratch. that is, you get sent to you 4-digit Code, enter this in the menu of the printer to continue setting up your account. I have set up several Scan-to-email accounts and tested them all and they work now just like before. The only witch hunt, I couldn't use the same EMail address of the printer as the connection HP site said that my old Email address was already in use.

    I am convinced that there is a change in the backend (cloud side) which requires you to remove & reinstall web services to make it work again. Anyway give it a try if you haven't already and hope this works for you as well.

    See you soon

  • Windows Fax and Scan cannot detect Photosmart C4580 all-in-1 scanner connected to the wireless network

    I have no problem printing or scanning when I connect my C4500 to PC via USB.  When connected via my home wireless router I can print OK but can not scan - it's the same for other users and computers.  Windows Fax and Scan gives me the message 'no scanner found. '  I need to work so that all users on my netwrok home can share the scanner.  I use Windows 7 64-bit.

    Thanks Travis_C (HP).  I actually found the solution just before receiving your answer!  I discovered that, although the Solution Center says it would uninstall the existing files before allowing me to reinstall with the latest version downloaded, it didn't remove all the files.  I only discovered this because the new facility has not taken me through the whole fresh installation procedure, he simply asked me what additional features I wanted to install and asked me if I wanted a local printer or network etc.

    I thought that there must be a mistake or problem with whatever existing files were left and the new facility would not correct it.  So I used the control panel to uninstall the existing files, and I made sure that everything was gone.  I then used the last download to reinstall, this time through the new correct installation procedure, and everything now works perfectly.

    With this method I always had a problem on another PC, giving me the same problem I had before.  I realized that this was due to a USB dongle connected to the PC to a wireless keyboard that seems to affect the installation.  When I removed the dongle installation worked again perfectly, and I now have full printing and scanning ability on all PCs.

    I think the installer for this printer wireless (and perhaps others?) should be updated to solve the problem, and also the center of Solution must be fixed to ensure that if you uninstall the software it should not leave anything.

  • Photosmart HP 7520: Do not copy

    Highest shown work in the office and our Photosmart HP 7520 will not copy. Used the automatic feeding system and the setting on the glass. I tried to color and BW. Document will display in the preview, but will be a blank page when you select copy. Tried a difficult start - same results. Printer scans very well. Printer can get documens sent to her very well. Just empty pages on the copy function.

    Is there a bulb or something grilled, which is required to copy? Any suggestions? Is this something that deserves to fix or just get a new printer?

    Appears more like a printing problem. Please try to print any page of the printer test. If she is still a Virgin, most likely related to the ink cartridges. Try following the below document and check if that helps

    Hi maggie101952,

    Thank you for the information on the computer.

    I would like to run a few things with you and with a little luck, we can get to the bottom of this issue.

    You have a memory card or a USB key connected to the printer?  If Yes, please remove and restart the printer.  Try printing without anything cards or USB connected.

    If is not the case, I'll give you the link for HP Photosmart 7520 series firmware update.  If the error is still popping up, the issue could be with the product it self.  I suggest you then call HP Technical Support to see all the other possibilities for you.
