After upgrading to lion 10.7 I can no longer use my canoscan 9950f, why?

After upgrading to lion 10.7 my canoscan 9950f scanner is no longer recognized. Have I lost thye use of this scanner by going to 10.7?

Not likely. Make sure the scanner is still available in System Preferences > Print & Scan. You might have to delete the old scanner and add it again if your computer cannot "find" it.
Before you do that, and while you are in Print & Scan, see if  you can get it to scan by selecting the Scan tab.
In Lion, all scanning functions have been relegated to Preview, the Print & Scan preference pane, and Image Capture.

  • After upgrading to Lion, my Canon 7d can not be found.

    After upgrading to Lion, my Canon 7d can not be found.  I have used the USB connection to connect to my camera for several years with no problems, until now.  I have reset the SMC, by powering off the computer and unplugging everything for approx 30 minutes.  There are no new drivers available and any assistance will be appreciated.

    I was having the same issue after upgrading to Lion OSX. I searched the web and found many people had the same problem but no solution so...
    I called Canon and they told me to run 'Image Capture' its part of the Canon Software Suite so you should have it and then try downloading the pictures like you usually do. I use 'Image Browser' and with 'Image Capture' running in the background it works perfectly now.
    Hope this helps!!

    Hello Jean,
    Based of what you have provided then I would say yes download iTunes from Apple’s website and also make sure that your version of Windows is up to date as well. Take a look at the article below to walk you through that plus some other steps necessary to get you back to using iTunes.

  • After upgrade to 10.7.1 users can no longer connect to shares

    Ok , im not an admin to start off, but after upgrading the OSX lion server to 10.7.1 i can no longer connect to the sharepoints on my mac mini server.
    Through SMB or AFP .. i tried using the connect to server on one of my clients and when i attempt to log in , it shakes the login window as if my password were not accepted.
    Heres where it gets a little confusing to me, i have 2 mac mini servers both running OSX LION SERVER 10.7.1 .... The one that I CAN NOT LOG INTO is my OD Master... the second one is just used for file sharing...
    WHEN i attempt to login into the file share server (which is connected to the OD Master which is rejecting my user logins) i can connect JUST FINE and access the sharepoiints on that server...
    A couple more weird things... on the OD MASTER (again the server which is rejecting all user logins) I CAN login with my admin credentials and access the sharepoints... ??
    -- when i am locally logged into the OD MASTER server, if i add a new sharepoint from scratch and edit the ACL , NONE OF MY USERS SHOW UP nor any of my user groups... it only allows me to add the Administrator access to that share..
    Have i done something very wrong somehwere? this server that is having a problem is only used as a OD master and File share nothing else..
    I did not change any settings besides add a new mac mini server to the OD and performa the 10.7.1 upgrade.
    ANY HELP WOULD BE HUGE as i have spent a 12 hours trying to figure this out before i resort to a re install.

    I've only one hint to you, cause I've mot on Mac-Server.
    With 10.7 Apple have switched from Samba (maybe due to licence problems with GPL based stuff) to a own protocol called "XSMB"
    This had caused problems with some NAS systems too.
    Eventually someone have a glue to solve that, as several users have problems with SMB shares since that.

  • After upgrading to 8.0.2 I can no longer send mail

    After upgrading iPad mini to 8.0.2 I can no longer send mail, only receive. Error msg "the recipient was rejected by the server because it does not allow relaying". Have tried rebooting, also resetting network connections, still no good.

    Hi maxwell156, 
    Welcome to the Apple Support Communities!
    I know that using Mail on your iPad is very important and is frustrating when it doesn’t work as you would expect. In this situation, I recommend reading over and using the information provided in the attached article to help the troubleshooting process.

  • After upgrading to 10.5.3 I can no longer login to my RedHat ES4 shares

    Hello,
    I am a new Mac user so please forgive me if there is a simple answer to this question...
    Since I installed the 10.5.3 update over 10.5.2 I can no longer login/connect to my RH ES4 (SMB Version 3.0.10-1.4E) shares. I can still login to my CentOS 5 (SMB Version 3.0.25b-1.el5_1.4) and my older RedHat 7.3 (SMB Version 2.2.3a) shares, as well as a few windows shares, without any problem. It is just the RH ES4 shares that I can no longer connect to.
    For legacy purposes I configured SMB on both my MacBook Pro and the above mentioned servers to use plain text passwords. To do this on my MacBook this I created nsmb.conf in /etc which contains the following...
    [default]
    minauth=none
    Everything worked perfectly minutes before the upgrade to 10.5.3 and nothing else in the network, software or hardware, has changed.
    Any help would be greatly appreciated.
    Thanks,
    Tom Boilard

    Welcome to the forums... unfortunately SMB issues are not fully mainstream.
    Anyhow, I have scanned the change log of files touched by the update (searching for SMB - original list courtesy of Rixstep). This yielded:
    /Library/Preferences/SystemConfiguration/com.apple.smb.server.plist
    /private/etc/smb.conf
    /System/Library/CoreServices/SmbFileServer.bundle/Versions/A/Resources/DesktopDe faults.plist

    Items highlighted in bold could be relevant.
    Have you checked that your entry in nsmb.conf is intact? If it is, could it be overridden by a change to one of the other conf files (or a plist)?

  • After upgrade to Firefox 6, certain sites can no longer be loaded.

    After upgrading from Firefox 5 to FF 6, certain sites will no longer load. These sites both use Typepad and that seems to be where FF6 hangs. Have not had this problem with FF5. Tried clearing cache, deleting bookmarks (to sites that won't load), and typing in address. That doesn't help. Sometimes, the sites load partly (i.e. with only words, no images); other times, load after a long time (several minutes); most often will not load at all.

    I've only one hint to you, cause I've mot on Mac-Server.

  • I can't turn on my Mac Book Air after upgrade the Lion software. Please, can you help me?

    I bought a Mac Book Air 3 month ago. I upgrade Lion software several hours ago. Later I reboot and I left to work. When I arrive, I can't turn on my MAC. Only light up the capital letter light, all the other parts are
    dead o seem to be. Can you tell me what I have to do to solve the problem, please?

    We can't, but Apple can, contact customer service, have your serial number ready and for a small fee Apple will send you a replacement.
    If you're in a hurry, go to the Apple Store and purchase a copy of OSX ($29 in the US)

  • After upgrading to 27.0.1, I can no longer access one secure site. I now get Error code: ssl_error_bad_mac_alert. This worked before the update.

    I am trying to access the GUI administration page of my wireless controller. It is using a cert issued by the vendor that makes it, so the names do not match. I have created a permanent exception for the certificate. Whenever I try to access the site, I now get the following error every time:
    Secure Connection Failed
    An error occurred during a connection to 172.24.6.10:4343. SSL peer reports incorrect Message Authentication Code. (Error code: ssl_error_bad_mac_alert)
    The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
    Please contact the website owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site.
    This page worked fine before the most recent update.
    Is there a setting or something I can change to allow this page to load?

    Thank you both for your suggestions. I had seen the possible solutions of time and ipv6, but those did not help. I cannot recycle the wireless controller, as that would disrupt my business's network too much.
    Cor-el, your answer was what worked for me. I went through each security.ssl3. setting like you suggested and found that
    security.ssl3.dhe_rsa_des_ede3_sha is where the error was coming from.
    With that one set to false, I was able to connect to the admin page again. When I set it back to true, the error comes back.
    I also found that specifically any one of the following were needed for teh connection to work as long as the one above was false.
    security.ssl3.rsa_aes_128_sha
    security.ssl3.rsa_aes_256_sha
    security.ssl3.rsa_des_ede3_sha
    so I am leaving the one that caused the error disabled and it is working again.
    Thanks!

  • After upgrading to Firefox 6.0 I can no longer get ANY youtube video to play. I already did the suggestion regarding my firewall.

    When I try to go on to the YouTube site I get a message from Firefox that says:
    ''''''''* * The connection has timed out
    * * The server at www.youtube.com is taking too long to respond.
    * * The site could be temporarily unavailable or too busy. Try again in a few
    * * moments.
    * * If you are unable to load any pages, check your computer's network connection.
    * * If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.''''''''
    I have already gone through the step you suggested to make sure Firefox is a trusted site with my security program, but nothing has changed.

    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
