After updating to Mountain lion I am having trouble printing to my wifi Epson printer

After updating to Mountain Lion I am having trouble printing on my wifi Epson Workforce 645. I keep getting an error message and my computer is set in the system prefrences to that printer

What is the error message?

This update also clears your "computer name" in Syst Prefs > Sharing, and entering a computer name solves network print issues for many.

  • After updating to mountain lion, icloud password has not been accepted by system preferences

    After updating to mountain lion my icloud password in the system preferences has not been accepted anymore. I already changed the password. Also the new one is not accepted by the system preferences. On iPhone and online everything is fine. Any idea?

    I just got off the phone with Apple Support. They say they are having problems with iCloud and this issue should be resolved in 3-4 hours. We'll see......

  • TS3276 hi after updating to Mountain Lion, it becomes difficult to quit Mail, always have to Force Quit. And while Mail is on standby, the fan keeps on running full power, the laptop is hot. Why is this happening?

    hi after updating to Mountain Lion, it becomes difficult to quit Mail, always have to Force Quit. And while Mail is on standby, the fan keeps on running full power, the laptop is hot. Why is this happening?

    If your computer was hot it wasn't asleep - it either didn't go to sleep or it work up after you put it to sleep. I've seen both things happen. First, read this article and follow the instructions.
    1) For the next few days/weeks pay attention to the blinking light on the front of your computer when you close the lid. Don't put the computer into your backpack/case until it begins to blink. Wait a minute or so after it starts to blink to make sure it doesn't stop blinking - the signal it woke back up.
    2) having followed the above instructions, if you take the computer out and it is hot again or if you take it out and discover it has powered down (you'll know this because when it starts up the battery will be drained and you'll see a progress bar over a ghostly display that will eventually become normal) immediately start the Console program and perform a search on 'sleep' and then 'wake'. This should bring up all the recent log files about sleep state changes (going to sleep and waking up). You should see one for when you put the computer to sleep and put it away and the next one should be just after you got it out. You'll find at least one though that shouldn't be there. That will tell you when the computer work up (when it shouldn't have) and might give a clue as to why.
    One of the whys could be a magnet that is making the computer think the lid has been opened.

  • Line 6 tone port gx doesn't work properly after updating to mountain lion, i'm hearing artefacts, how is that possible?

    i am using logic 9 and line 6 toneport gx for recording my guitar. on the previous version of OSx everything worked perfect, but now, after updating to mountain lion, i hear noise after i play something. the settings were: input: toneport, output: coreaudio, 44100, buffer 512. now they are the same and i have noise. i've installed the latest drivers for toneport and changed the buffer settings. when the buffer is large, i can play some seconds without the noise but it appears after 15-20 seconds. and when the buffer is small it appears faster. i assume it has to do something with the buffer size but i don't know for sure. any ideas?

    I have the same problem after updating to ML. It's unusuable for recording until it gets sorted out.
    I think it's a problem at the Line 6 end. They are aware of it, and are working on some patch/fix to address the strange artifact sounds, so hopefully it will be ready soon.

  • After updating to mountain lion on my mac pro I am unable to connect my g-raid

    After updating to mountain lion on my mac pro I am unable to connect my g-raid 1T external hard drive using the firewire connection? I have 4 places to plug the firewire into, none work. All ports used to work with Snow leopard?

    Try this:
    Boot into Safe Mode then restart normally.
    Repair the Hard Drive and Permissions - Lion/Mountain Lion
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
    If this does not work to fix the problem, then:
    Reinstalling Lion/Mountain Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • Since the last software update for mountain lion I am having a problem when moving screenshots to trash. Now a Finder box appears saying finder wants to make changes and I have to enter my password for every action.

    Since the last software update for mountain lion, I am having a problem when trying to remove any screenshots to the trash. A box appears saying "Finder wants to make changes. Type your password to allow this"
    I have checked Finder Preferences and cannot find any box that I can 'UNTICK' to resolve this. I sometimes take a lot of screenshots when I am researching something and now find I have to enter my password for every screenshot to be removed to trash.
    Anyone got a solution please, Thanks

    A brief search. Or even glancing at the "more like this" list to the right will show that this is a known problem and there is no current solution. Workaround includ saving to the desktop and importing from there or opening in Quick Look and adding to iPhoto from there

  • After upgrading to mountain lion my calendar does not print in weekly mode anymore

    after upgrading to mountain lion my calendar does not print in weekly mode anymore

    I'm having the same problem with both my Vivotek wired network camera and Panasonic wireless network cameras. At first I thought this was an issue with the video framework in Mountain Lion, but if Firefox is working (I haven't tried it yet), it sounds like it may be an objective-c video library that has been changed. It's possible Firefox is using an objective-c interface that calls an objective-c function that isn't called by Safari or IP Camera Viewer, etc., (possibly a function that is on its way to be deprecated) or Firefox could use it's own library that directly calls the video framework.
    Could be the Mountain Lion objective-c framework has a buffering issue.
    Since this is occuring in both 3rd party software and Apple software, it sounds like it's an Apple issue. 3rd party applications typically utilize the Apple Developer objective-c frameworks to access video frameworks/libraries (for example, MJPEG). Thus, contacting 3rd party developers may not solve the situation (unless they can figure out a temporary bandaid--possibly figuring out the video framework call that Firefox uses and patching their software to do the same (not a simple task), but could still provide more feedback to Apple via their developer status.
    Has anyone attempted to record from their cameras via iMovie or Final Cut Pro X HD? I will try mine later tonight to see if it records the hanging. If it does, then it's looking more and more like Apple's the culprit.
    My suggestion is for everyone to file a bug report via http://www.apple.com/feedback/macosx.html

    Hi Al,
    Long shot, but...
    Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there, some things will change it for their own use, then not set it back.

  • Odd error message that started after update to Mountain Lion

    Ever since updating to Mountain Lion, I get this error message every now and then:
    Nothing in particular seems to cause it, and there isn't a server to which I'm trying to connect. My computer is a mid 2010 MacBook Pro
    Can someone tell me what this means in the first place and how I can fix the problem?
    Thanks!

    Open the Time Machine pane in System Preferences. If it shows that Time Machine is ON, click the padlock icon in the lower left corner, if necessary, to unlock it. Scroll to the bottom of the list of backup drives and click Add or Remove Backup Disk. Remove all the disks, then add them back. Quit System Preferences. Test.

  • Constant Crashing of iPhoto after updating to Mountain Lion and iPhoto 11

    I recently updated to Mountain Lion and also to iPhoto 11. iPhoto crashes constantly. From reading other posts I opened while holding the option key and started a new library. It seemed to work then, but now what do I do to get my old photos?

    That is a test and it shows that the application is ok. The problem is with your library. Not to data (the library)
    So the next thing is to see if we can fix your library. Go back to your main library and post the first 50 lines of  the crash log. Also any error message, recent changes, any other observations that might help
