System Preferences hangs at "Loading Print & Fax..."

Hi,
I tried to load a Canon printer driver for the ir1023. After the install it required a restart. The Mac Pro never fully turned off, so I was stuck having to do a manual shut down with the power button. I am sure this messed everything up.
When I logged back on System Preferences hangs at "Loading Print & Fax..." when I click the icon. So I deleted the printing preferences, from my preferences folder and still nothing.
I ran the canon installer and that ran successfully, but did not remedy the problem. No Mac programs will print, Photoshop will not launch and Text Edit won't quit.
I ran Disk permissions from the Leopard disk, still no improvement.
Any ideas on how to fix my printing woes without a reinstall?
And I was having some hardware issues with my Time Machine drive - so I had no backup to fall back on.
Thanks!

I would run the UFR2 driver installer again, but when it shows Easy Install at the Installation Type pane, change the menu to Uninstall. This should remove all the UFR2 files, most of which are copied to ./Library/Printers/Canon/UFR2.
With the Canon files removed, try to open the Print & Fax pane again. If it still fails to load, you could try opening the CUPS web page (http://127.0.0.1:631). From here you can select the printer list and job list and possibly remove any existing printers or jobs that are in the system. Ideally we would like to reset the printing system, but I don't think we can do this from the web page or from Terminal - we need the GUI of Print & Fax.
Will do some more reading and get back to you....

  • System preferences quits when clicking print&fax

    Every time I open print&fax in system preferences the application stalls for some seconds and then moves to the next window. but when I click on the plus to add a printer it stalls again, then opens the window to search for printers, then the application (system preferences) quits. It's beginning to get very frustrating and I never thought I would have a problem like this with a Mac. How do I fix it? Should I take my Macbook into a retail store for help?

    figured out the problem finally. turns out my hard drive was defective and dying out, which seemed to be causing the sudden hesitations when opening up certain applications. unfortunately i found out the hard way and my hard drive crashed with all of my info. they replaced it but ALWAYS BACK UP YOUR FILES!!

    Best regards, Mikkel

    To further explain:
         I didn't need to locate any invisible files in my case.  I discovered that I had 4 versions of the System Preferences application on my computer.  (The System Preference applicatioin is what loads the preference pains when you seledt System Preferences.)  I merely searched for "System Preferences" in spotlight.  Spotlight located 4 different versions of the System Preferences application. Some of those versions apparently tied to preference panes that used the old 32 bit encoding from the non Intel processor days.  When I clicked on the System Preferences under the Apple menue it was apparently pulling up an old version of the System Preferences applicatioin instead of the correct one in the main Applications folder.  I also noted that if I clicked on System Preferernces in the dock or directly in the the Applications folder, I would not have the problem of some of the preference panes not able to be viewed because of the " "it doesn’t work on an Intel-based Mac" message.  So I surmised that the correct System Preferences application was in the Applications Folder on the top level of the drive directory like it was supposed to be but that when I clicked on System Preferences from the Apple menue it was loading one of the 3 old System Preferences applications that were buried elsewhere on my hard drive.  If you find you have more than one System Preferences application on your hard drive you need to trash the other System Preferences Applications.  Before trashing the duplicates, you should test the one in the main Applications folder by directly double clicking it and make sure all the preference panes in it work properly then trash the duplicate System Preferences applications you found in spotlight.
         You may also find like I did, that you not only have duplicates of the System Preferences on your hard drive but also several old duplicates of the entire Applications folder buried on your hard drive. if that is the case you should compare each folder and make sure there is nothing in the old duplicate Applications folders you still need.  You will probably find that all of the latest versions of your applications are in the main Applications folder where they should be.  If so then trash all the old duplicate Applications folders as well.  Keep only the main Applications folder on the top level of the hard drive.
         Trashing all these extra old Applications folders that held old duplicates of all my applications in them on my hard drive solved a bunch of other problems I was having with some of the applications as well.
         For the technically minded:  Why does this happen with Mavericks and not with Mountain Lion?  I suspect that the old Applications folders and old duplicate System Sreferences applications didn't matter to Mountain Lion because it searched for the System Preference application under the Apple menu differently than Mavericks does.  I believe Mountain Lion seached all the top levels of the Application folder before drilling down into any subfolders to find the System Preferences application.  Mavericks apparently does it the opposite way.  It searches the first subfolder in you Applications folder and drills all the way down in that subfolder first before going to the next subfolder and drilling down in that subfolder all the way to the bottom.  So it searches all the subfolders before searching the main level of the Applications folder for System Preferences.  Since my old duplicate System Preferences applications where in subfolders with titles that were earlier in the alphabet than the main System Preferences application it searched those subfolders first, found the old System Preferences application in the those earlier folders and loaded the old System Preferences first in the subfolders instead of the correct one further on in the main Applications folder.  If any one else has a better idea let me know.

    Welcome to the Apple Support Communities
    Try to delete the Desktop settings file. First, open Finder, select Go menu > Go to Folder, and type ~/Library/Preferences. Then, delete "com.apple.desktop.plist" and "com.apple.systempreferences.plist", and restart. Finally, you should be able to go to Desktop and Screen Saver on System Preferences

  • System Preferences Hanging

    I upgraded my First Gen Macbook to Snow Leopard when it came out. Just recently however, I have started having a problem with system preferences. The first time I open system preferences, it hangs, stalls, and crashes. Once I force quit it, I can launch it normally. So recap:
    Launch System Preferences: Hang, Force Quit
    Re-Launch System Preferences: Open immediately
    A minor annoyance but still an annoyance

    You are not alone friend, I have a 1st gen Macbook Pro, fresh install of Snow Leopard, new user account, NO migration, all updated, and all voodoo done as well (repair permissions, chkdsk, blah blah blah). I have to launch System Preference, watch it hang, force quit, and relaunch successfully. Works that way EVERY time. If I wait too long, I can't open it. Now I open it and just leave it open all day. If I didn't change so many settings so often, I wouldn't care. This entire experience of upgrading to Snow Leopard has sucked. Shame on you Apple.

  • System Preferences hangs with Mountain Lion

    Various parts of system preferences hang under Mountain Lion.  Prior to upgrade there was no problem. Any ideas?

    I am still having this problem as well.  Multiple panes will fail to launch.  A reinstallation of ML failed to fix this.  I even did a fresh reinstall, manually copying over my Documents, Music, Pictures, and other essential files to a backup drive beforehand.  Almost all System Preferences fail to launch.  A list of those that fail:
    Desktop & Screensaver
    Security & Privacy
    Notifications
    iCloud
    Mail, Contacts, & Calendars
    Date & Time
    Software Update (The only one that seems to extend beyond the preference pane.  Software update will not launch, even though I know there are iPhoto and iTunes updates to be downlaoded.)
    Dictation & Speech
    Time Machine (I really, really, really, really, really want this one to work!)
    Startup Disk

  • System preferences hangs

    installed ML, but system preferences hangs so can't change any preferences.It opens the icon, but the window never appears.
    I have re-installed - but same happens
    moreover, I can't get it to restart without forcing a quit by turning on/off button (it hangs on the blank 'light grey' screen)
    I have checked repair permissions, no problem there.

    On my MacPro:
    My problem began with a nearly non-functioning Mail program after upgrade to OS M Lion, which is detailed in my post a few days ago. After trying everything I could to resolve it unsuccessfully, (rebuild directory structure, fix permissions, trash preferences for iCloud apps, zap PRAM, and several other efforts, including a reinstall of M Lion from recovery drive) I contacted Apple Support and ended up on the phone with a rep.  We set-up remote access so he could see the Mail hang-up everytime I attempted to fill in the outgoing email address field in a new message window (spinning ball) - it took up to 30 sec for each letter I typed to appear and overall about 2-3 minutes to completely populate the field with the address. All other Mail functions were working better, but seriously sluggish.  We tried disabling each email account, one by one to see if another account was causing the problem (my primary account is a .me address).  No problem with other accounts.  Then the unexpected happened.  He asked me to open Safari and log into iCloud so we could see if Mail was working via the web.  Upon login, the icons for all the iCloud applications appeared with completely corrupted text labels under each icon...  each was a mix of letters and symbols stacked on top of each other.  It appeared that my entire iCloud account might be corrupted. However, testing the same login via Firefox worked just fine, so the issue was narrowing to iCloud and interaction between the default apps between this computer and iCloud via Safari.  We then attempted to open Contacts from Launch Pad on HD - It opened, but none of my contacts were there.  Further indication of iCloud account corruption. Since I am able to access and use all iCloud features and apps on my MacBook Pro, an early assumption is that the OS upgrade to Mountain Lion on my MacPro may have been severely corrupted.  Before going so far as to do a clean install of M Lion, we installed a Data Capture program and I ran through the attempts to set-up and send a new email while it captured all system activitiy in that process.  This data and the screen captures obtained during this session have now been sent up to Apple OS engineers to dig into and figure out why, and how a corruption of the ML install could have occured. I have agreed not to do a 'clean install' of the OS until the engineers get back to me as they may need to run more remote diagnostics on this computer to narrow it down to the actual cause.... this, so that a fix can be implemented before countless other computers are effected.  I am scheduled to hear back form them today or on Monday and I will post the results here. They seem quite busy with bug fixing right now.  The toys and features of Lion and M Lion are very cool, but I am seriously beginning to miss the speed and reliability of Leapord/Snow Leopard.... even Tiger - I fired up my old G5 tower with Leopard ... it is amazing just how fast and solid it is compared to these new OS builds that feel and look more like virtual machines than a real Mac OS.   I hope all these diagnostics and interaction with senior engineers provide some solid solutions soon.

  • System Preferences Hangs After a Successful Sync to .Mac

    Okay, I think this is going to be a tough one to track down, but I'm hoping you guys can help.
    Problem: When I manually sync my data to .Mac using the .Mac area of System Preferences, System Preferences hangs right after the sync process completes.
    If I manually start the sync in System Preferences and then quit System Preferences while the sync is in progress, the sync completes with no ill effects (i.e., because System Preferences is no longer running, it can't hang when the .Mac sync completes).
    Things I've done to address the problem:
    (1) Trashed com.apple.PreferenceSync.plist (restart system and try recreating the problem ... no change).
    (2) Trashed the contents of ~/Library/FileSync/ (restart system and try recreating the problem ... no change).
    (3) Unregister my computer from .Mac, delete old sync data, and re-register my computer with .Mac (as I said, the .Mac sync completes, so this was just a shot in the dark ... restart system and try recreating the problem ... no change).
    The system.log records the following when System Preferences hangs:
    Jun 7 00:07:31 Joel-McIntoshs-Computer System Preferences[401]: exception while performing selector syncPlanWithIdentifier: on server: NSPortTimeoutException connection timeout: did not receive reply
    Jun 7 00:07:31 Joel-McIntoshs-Computer SystemUIServer[107]: exception while performing selector syncPlanWithIdentifier: on server: NSPortTimeoutException connection timeout: did not receive reply

    Jun 7 00:07:31 Joel-McIntoshs-Computer System Preferences[401]: * Break on _NSLockError() to debug.

    Thanks for the help. I think I've tracked down the problem.
    I created a test user and the sync and system preferences worked fine.
    I started trouble shooting by going back to the main account, and testing item by item various third-party "items" that were present in the main account, but that were absent in the test user account. I removed most third party "stuff" and started adding it back in one at a time and testing sync with each addition.
    I finally recreated the System Preferences hang after I installed TextExpander -AND- had .Mac sync checked in the TextExpander preferences (it didn't hang if that box was not checked in TextExpander). Unchecked, no hang ... checked hang.
    I've contacted the developer for assistance.

  • System Preferences Hang

    I've just recently been struggling to print on my HP Laserjet 1020 and a Canon all in one and uninstalled both of the printers and rebooted my laptop. Now the System Preferences screen hangs when I click on the Print/Fax option. Any suggestions on how to fix this?

    Maybe try to go to your user/library/preferences folder and remove com.apple.systempreferences.plist and possibly another one relating to the print preferences (not sure which), and restarting?
