HP Officejet Pro L7780: HP Officejet Pro L7780 Solution Center does not work even though I can print

Last week, Solution Center of my printer HP Officejet Pro L7780 stopped working, even though I can still print directly from applications. But I can't use the scan feature. I uninstalled and reinstalled the driver full several times (after uninstalling using uninstall_L4, cold restarted the printer, remove the DigitalImaging registry key and delete all the files in %Temp%). The re - install seems to be okay except that when I try to open the solution Center, it happens nothing except sound.

Any ideas how to solve this problem?

Thank you.

  • HP Officejet Pro 8500 A909a_ Scan with HP Solution Center does not work


    My name is Michele.

    I can't use the solution Center HP to scan with my HP Officejet Pro 8500 A909a (I have windows 7 O.S.) because when I click on "Scan document", a white error window appears and says "necessary component is unfounded or not properly installed.". Install new software HP Photosmart". I uninstalled and again installed the software, but it does not work. Previously, he worked with XP. Recently, I updated XP with Windows 7 and I found the solution Center HP does not work. Maybe, it does not match with Win 7?

  • OfficeJet L7680: HP Solution Center does not load

    This morning, HP Solution Center will not load - just a tone of my computer and nothing loads.  I uninstalled all the HP software and reinstalled a fresh copy of HP Officejet Full Feature Software and Driver (v14.8.0) Pro.  Everything was working fine a few days ago, but my computer did an Auto-setting Windows update last night.  Could this be the problem - some new incompatibility?

    Thank you.

  • Solution Center does not work under Windows 7 with Officejet Pro L7780

    Downloaded the latest version of the software for Windows 7 and the first issue was when you try to do an installation complete you get a fatal error at the 96 percent mark when she did the configuration. I looked on the web and found a lot of posts on the same problem. Then, I just uninstalled and made a gradual installation.

    Main printer DRIVER installed first. Then did the functions of imaging followed by the solution Center device.

    Installed everything, but when you run the solution center it says it can't open because incomplete installation.

    The printer works from Windows 7.

    I have an XP machine and Solution Center working on it.

    Any suggestions anyone.

    This thread has resolved the problem installing the software that supports the HP Officejet Pro l7780 for use on Windows 7.

    The event viewer showed mistakes that network location for %APPDATA%\protector.exe is not found.

    Even if I couldn't run the original installation of solutioncenter.msi to work without errors in the log file, without making any changes, which has not completely solved the problem.

    Since solutioncenter, initially did not work, I decided to run solutioncenter.msi manually and look at the log file. See errors in the log file we made changes to the database with Orca solutioncenter.msi. It took us on a long road that does not initially sense that HP would put something out there that produced errors in the msi log file.

    I don't know how the setup.exe uses solutioncenter.msi?

    The changes that doesn't seem it to matter when you run the setup.exe file that is provided in the download.

    If I used the modified solutioncenter.msi or version orginal of it as downloaded from HP running setup.exe site had no importance regarding obtaining solutioncenter work in windows 7, canceled only changes in the solutioncenter log file errors.

    I had to make the following changes to the environment variables to get the full package to work, but what is strange is that I could replace the changeed solutioncenter.msi or the original solutioncenter.msi and run setup.exe, with the following environment changes didn't matter. The solution Center has worked in Windows 7 using one of the solutioncenter.exe and setup.exe.

    Apparently, setup.exe does not use the MSI directely. I think that HP responses suggested that in a previous thread.

    Add these entries (click new...) for the owner user variables and System variables:

    In the name box: APPDATA

    In the value box: %USERPROFILE%\AppData\Roaming


    Run setup.exe and event viewer does not display % APPDATA % Scriptures and all work.


    Thanks for all help on this.

  • HP HP Officejet 4500 g Solution Center: does not open. Worked yesterday morning, did not work yesterday afternoon.

    Hi all!  Yesterday morning, I scanned in some documents by using the Center, HP solutions, and later in the day that I was not able to open the Solution Center and got a message saying that my installation was not complete?  I've used this for years with little problem.  I also ran printing HP and Scan doc and shows the printer installed, but when I continue it said that I have to reinstall.

    I took the printer to the printer menu, added the printer, but still no luck.

    I watched 10 Windows update and found that a lot has been downloaded yesterday some time.  I wonder if anyone has reported problems with updates.  This happened again and when I uninstalled the offending file, everything was fine.

    I can print, I can copy, but I can't scan which is very convenient.

    I'm not trying to uninstall and reinstall everything just because it creates more problems...

    Any thoughts? Help!

    Mary Anne

    OK, I uninstalled and reinstalled.  I was not as painful as I expected.

    Works fine now.

    Thank you!!

  • OfficeJet 4580: HP Solution Center does not

    I installed Windows 10 maybe a few months ago.  Everything worked well until recently.  When I tried to use the HP Solution Center the other day, that it does not open.  The program flashes on momentarily, then disappears.  I prefer to use the HP software for scanning and printing, but now I am unable to access.  Had a recent update of Windows 10 which would cause this error?  Can we do anything about it? I have unlinstalled and reinstalled the driver for my printer from the HP website.  It is updated as much as possible.  Solution center 14.0 is installed now.  Thanks for any help.

  • OfficeJet 8500 a 910 scan does not work with my Macbook Pro Snow Leopard 10.6.8

    OfficeJet 8500 a 910 scan does not work with my Macbook Pro Snow Leopard 10.6.8.  I tried to reload of apple and HP.  My drivers and software are up to date.  I tried to scan from preview, Capture and print browser.

    It worked finally.

    Why doesn't HP have updated the drivers for a Macbook Pro 10.6.8 Snow Leopard?  I couldn't find one for 10.5 or 10.6 Leopard.  I tried everything I could find. I found a note on the edge of Disussion which suggested someone try a driver for another HP printer may be similar.  I found if I used the full program for Macbook Pro 10.6 Leopard I could scan.  The fax appeared to be installed via blue tooth.  I have not faxed anything, but it has been tested during the installation of the program.  Complete program of the HP I can't print.  I loaded via Apple an another whick of printer HP Officejet 8500 A910 allows me to print.  It is the only way that I could make use of my HP printer, scanner and fax.  Crazy, but I think it works and I can put some scans and, hopefully, fax to my Macbook Pro.  I appreciate the help.  Please encourage the HP programs and drivers for my Macbook Pro Snow Leopard 10.6.8.

  • Satellite Pro L850 - keyboard / touchpad does not work

  • Satellite Pro C650 - cooling fan does not work

    My Satellite Pro C650 overheats and stops automatically within 20 minutes of leaving upwards. I checked the CPU fan and noticed that it does not turn upward, even if the laptop would become very hot. I tested the fan with a 9 volt battery and it works perfectly.

    Can someone tell me exactly what the problem is? And how to solve it.

    Thank you.

    > Can someone tell me exactly what the problem is?
    On this virtual path, no one can say with certainty what the problem is. We can only speculate what may be the problem.
    Usually, cooling fan starts immediately after starting the laptop slows down and offers the optimum temperature of material. After reading your ad I didn t understand how it works. He turns and there is no sign of life?
    Problem can be power.
    Cooling fan will be controlled by sensors of temperature and activity depends on the temperature of the material but if your machine cooling fan does not work, I imagine that there is no electric power.

    What do you think?

  • Satellite Pro M30-701: TouchPad does not work after installation of XP Pro

    My touchPad does not work after reinstalling XP Pro OS with recovery disk. I install a driver for Toshiba M30 - 701 Synaptics TouchPad tpdrv-sp-m30-xp - 7920.zip

    Can you help me solve the my problem please?
    Excuse my bad English...
    Thank you
    Jorge Neto

    HI Jorge,.

    If you have reinstalled your system using the Toshiba recovery disks the touchpad should have the right drivers and be fully functional. I seem to remember that it is possible to disable the touch pad using one of the "keyboard shortcuts" (F9 on my SA30) in order to check that it has not been inadvertently pressed.

    Kind regards

  • Re: Satellite Pro S500 - brightness adjustment does not work correctly

    On my Satellite Pro S500 (preinstalled Windows 7 64-bit) change the brightness by pressing FN - F6 or FN + F7 does not work. The other NF - f... combinations seem to work correctly.

    When I press FN - F6 (or F7) a control box to change the brightness to poster (as expected), but the level is still displayed as "1" independent of the current value (for example changed from Control Panel or with the eco utility) and it is not possible to change it with FN - F6 or F7. I just reinstalled vap and restarted the computer, but nothing has changed.

    Hi asdf.

    I put t know what s wrong exactly but normally the FN keys are associated with value added Package, but you wrote that you already reinstalled

    In my opinion, you should try a system restore to an earlier point. Maybe something messed up the registry, you can start System Restore in Windows Advanced Boot menu.
