Photosmart 7520: Prints but won't scan Photosmart 7520 Win7 and Win10

Very well printing - scanning fails in both directions, of PC to the printer and the printer to the PC.

No form of works-y PC using the HP device Page or print and Scan doctor.  All two see the printer but when they try to connect give the message error «scanner communication can not be establshed...» »

If you go to the printer itself and try a "Scan to PC" the printer sees name of the PC, but when you click Scan an error message comes up saying "no computer connected.

Having exhausted all the recommended solutions: uninstall and reinstall the drivers. Run Selective startup without any service has been activated; Print and Scan Doctor (tells me that there is a problem of TWAIN, but even then gives error "can' communications Scanner...", even after the PC reboot and repeat the doctor P & s); restart the router method.

The only method of scanning that work which means the network is scanning to E-mail.

Any ideas?

Hey @grunte1,

Welcome to the HP Support forums!

I see that you encounter some problems with the scanning of your 7520 Photosmart e-all-in-one printer to your PC for Windows 10 and that the printing and scanning doctor detects a problem with your TWAIN drivers. As TWAIN drivers refer to a component of the operating system, the only things I can suggest are updates or perform a system restore. In addition, I suggest contacting the one who sold you the PC or the Microsoft.

If you have any other questions please let me know. If not, have a great day!

  • MX710 - I can print but can't scan

    I just got a new Mac and can't figure out how to configure scanning.  I use MP Navigator EX scanner and it does not recognize the scanner.  Wireless printing works fine however.

    It shows Canon MX710 tab Printers/Scanners, but hangs there when I try to scan from this application.

    I'm sure it's something 'order of installing the drivers', but I can't seem to understand this.

    Any help is appreciated.

    I found the solution:

    In the software MP Navigator MX, click on Preferences and in the name of the product drop-down, select "MX710 series network" rather than "MX710 series.

    Hey people,

    I have the Officejet 6500 Wireless that works find. I have connected it to my laptop and can print/scan/fax without problem.

    I recently bought a desktop computer and it fines the printer without a problem and I printed.

    How to scan?

    On my laptop, I have the HP Solution Center, and that's where I control the scanning from. I downloaded the software from this site and installed on my desktop, but it does not install solution Center, so I can't scan.

    I have Windows 7 on the desktop.

    It would be much appreciated to help explain how to interact with the scanner.

    Thank you

  • Canon MG7100 prints but will not scan after update of the iMac? How to fix?

    Canon MG7100 worked very well with the iMac - scanning and printing. After doing the updates of the iMac and installation Siri scanning does not work. Always printing. The printer/scanner Canon said - Set PC to start scanning - I have MG7100 added on the iMac. I opened (and re-locked) firewall to let in the Canon UJ utility. I deleted the all-in-one Hi - and added MG7100.

    http://support-Asia.Canon-Asia.com/contents/Asia/en/0100535401.html

    doesn't look like canon has a printer that takes in charge the newer versions of Mac OS x, if I were you I would take contact them to see if they plan on support of new versions, apple made no drivers for the hardware they don't and if hardware manufacturers does not provide a working driver head can group with the new version of Mac OS x We have to rely on manufacturing to have a download on their page

  • LJ 400 M401dn: Windows 10 'sees' printer, but won't print

    When I go to print, I get a print error of not being able to print to the print queue so online.  I downloaded all-in-one and tried to install it as a solution after uninstalling the printer.  After 99% installation expires will fail.

    I tried to install through Windows Update.  This installed a 400 M401 of LJ that lists as a Color LaserJet.

    A couple of days, I was able to print and do not know what has changed.

    Someone at - it an idea on what is happening and a difficulty of the dose.

    Windows 10 64 - bit, dn LaserJet M401.

    I found the solution, and it is up to the peculiarities of Windows 10.  In previous versions of Windows, when you initially configure configuring as administrator and users created.  10, configuring users and if the user can have administrator rights, they are not really a full-blownAdministrator.  So, during my installation has been blocked by the administrator, I was curious.

    You need to activate the hidden administrator account, sign in as the 'real' administrator and then proceed with the installation form here.

  • Suddenly won't scan hp 8600 function, and the hp Solution Center does not connect?

    I have been regularly using scanning, copying and printing to my HP 8600 printer features 4/1. All of a sudden when I click on the printer icon only functions of the printer are listed. When I click on the HP Solutions Center (which I have not had to do was s/u w / a previous printer) the message says: HP Solution Center cannot run b/c your device installation is not complete. PLS, connect the cable usb or re - run the Setup program from the installation to a network installation CD. If this does not work...

    I insert the CD, re-directed the s/u and nothing has changed. Please notify.

    HP 4/1 8600

    Windows 7

    I see that you have had previous HP products, Katharine. I'm glad to know that you have the software installed for the 8600 with success now.

    However, the center of Solution software you used with the previous units is more used to the 8600. The software installed for the 8600 should have placed an icon that resembles the printer with the name of the printer it labeling on your desktop. This icon opens the wizard of HP printer with options to control the printer.

    Good impression!

  • The HP 8600 printer settings changes do not work with win7 and internet explore v11

    I can connect to my printer using my IP address IE 11 and I watch a lot of things, but if I try to change something simple, like the weather, I get an error message back indicating an invalid entry.  However, if I use Firefox v26.0, it works fine.  I have the latest drivers installed on my laptopt.  This can be solved?   I do this from time to time because the clock on the printer does not keep accurate time.  Apparently, there is no solution for it.  (other than adjusting them manually from time to time)

    My Windows 7 laptop does not recognize my wireless scanner HP 2710. I can print wireless, but analyzed only if connected via USB. Anyone has a solution.

    Thank you JBBLCC

    I'm having the same problem. Can connect to print, but does not scan using Windows 7 and HP Photosmart 2710.

    HP's web site says that they do not have a Windows 7 driver that works for all. You will need to connect your computer to the device via USB to use the scan function.

    http://h10025.www1.HP.com/ewfrf/wc/document?DocName=c01796736&LC=en&DLC=en&cc=us&lang=en&OS=4063&product=420428

    If all goes well, HP will find a way to generate a driver that allows all features of their unit to operate wireless with Windows 7. I can do both print and scan using my other Windows XP laptop and desktop using wireless driver HP Windows XP.
