IMac doesn't recognize HP 4635 Scanner

The Scan program that comes with the 4635 doesn't recognize the scanner. I can scan using Photoshop or Image Capture. The printer works fine.

Hello , and welcome to the HP Forums, I hope you enjoy your experience! I see you're having problems scanning.  I would like to help! I would suggest deleting the printer from your print system, using this document: Uninstalling the Printer Software. Once you have deleted it, I would suggest verifying and repairing the disk permissions: About Disk Utility's Repair Disk Permissions feature. I would also suggest running your Apple updates:  OS X: Updating OS X and Mac App Store apps After the updates, I would recommend reinstalling the printer: HP Officejet 4630 e-All-in-One Printer series Full Feature Software and Drivers Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums!

  • The iMac doesn't recognize my external hard disk

    My iMac doesn't recognize my external hard disk. The iMac also keeps a DVD inside. It doen't throw it out despite "eject".

    Sounds like you might need to make that call. In the meantime here are a few of things you could try that may help:
    To eject the disk try a restart holding down the mouse button - hopefully it'll eject.
    If you are running either Mountain Lion (10.8) or Lion (10.7) try booting into the Recovery HD:
    Restart holding down Command+r. At the screen with 4 choices choose Disk Utility and then select Macintosh HD and click on repair disk. If it fixes anything click on repair disk again until you get a clean pass. Restart as normal from the Apple menu.
    If you are running an earlier OS you would normally carry out this process by putting the grey restore disk that came with your Mac in the Disk drive and restarting holding down the C key. Choose your language and at the next screen from the menu bar select Utilities>Disk Utility and then follow the above instructions (I realise you won't be able to do this if you have a disk stuck in the optical disk drive).
    Try an SMC and PRAM reset: https://discussions.apple.com/docs/DOC-3603
    Try a Safe Boot: Restart holding down the shift key until you see a grey progress bar. Once it's booted restart as normal from the Apple menu.
    If none of this helps, I guess you need to make that call. Good luck.

  • New imac doesn't recognize firewire 400

    Just got the new imac and transferred all data from my old (non-intel) imac using a firewire 400-to-800 adapter.
    Now, my new imac doesn't recognize my external (400 firewire) drives anymore. One of the drives has an USB which works with the new mac but transfers are very vey slow. The other drive has only firewire 400 and doesn't get recognized at all.
    Any solutions?
    Thanks.

    Adapters can be troublesome, I'd recommend replacing with a Firewire 400 to 800 cable like this one. You can normally find these at your local computer store, Radio Shack or of course Amazon.

  • Adobe Acrobat NI Pro doesn't recognize my wireless scanner, a Canon MG5520, but it prints from the same MG5520. This is ridiculous!

    Adobe Acrobat NI Pro doesn't recognize my wireless scanner, a Canon MG5520, but it prints from the same MG5520. This is ridiculous!

    I just used the "Quick Menu" in Adobe Acrobat XI Pro after wasting hours several days when the SSID and Network key/password were already activated and the Adobe software claimed no scanner was available. . These Adobe user manuals are next to useless. Now I'm still dealing with this problem: "Save As was unable to find tables in the document No file was created." (i.e., from the pdf file I created using NI). Well it's obvious there are tables in the pdf, but so far I haven't been able to get a result to determine the intrinsic accuracy of Adobe's pdf to Excel capability.

  • Photoshop elements 13 doesn't recognize my Epson scanner

    I have a Epson Workfoce 545 wireless printer/fax/scanner and newly installed Elements 13 doesn't recognize the scanner.  Do any of you in this community have a suggestion? 

    The scanner is NOT present in the network.  The "all in one printer" that the scanner is a part of  is listed, however.

  • Can't burn data to a CD because iMac doesn't recognize CD has been inserted.  Also, can't eject.  What to do?

    Can't burn data to a CD because iMac doesn't recognize that a CD has been inserted.  Also, it won't let me eject the disk. How do I get my iMac to let me burn the data to the CD and eject the disk?  
    Finder currently has 2 "Untitled CD"s listed in it.  One has been in there for months (without a CD inserted into the machine).  I have tried several times unsuccessfully to remove the item from finder.

    Please reset the SMC and PRAM 2-3 times each using the instructions in https://discussions.apple.com/docs/DOC-3603.  Then attempt to eject. If that fails please use one of Kappy's ideas:
    Five ways to eject a stuck CD or DVD from the optical drive
    Ejecting the stuck disc can usually be done in one of the following ways:
    1. Restart the computer and after the chime press and hold down the left mouse button until the disc ejects.
    2. Press the Eject button on your keyboard.
    3. Click on the Eject button in the menubar.
    4. Press COMMAND-E.
    5. If none of the above work try this: Open the Terminal application in your Utilities folder. At the prompt enter or paste the following:
    /usr/bin/drutil eject
    If this fails then try this:
    Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.

  • My imac doesn't recognize my backup drive anymore,what can i do?

    My Imac doesn't recognize my backup drive anymore,what can i do?

    Unfortunately, that usually means the drive has died although it doesn't mean some other hardware failure or even software failure (in some cases.)
    I think the wise thing to do is take it in for service.

  • IMac doesn't recognize input devices after going to asleep, must reboot

    Quite often, my iMac doesn't respond when I attempt to "wake" it using keyboard or mouse. The only way to wake the iMac is to tap the power button. However, when it wakes the mouse cursor is a spinning color wheel and the system does not recognize any input from the keyboard or mouse. I can leave it sitting for quite some time and it still will not recognize my input devices. When this happens I must hold the power button to reboot.
    This has been happening for a quite a while now, and it is highly annoying. I can't remember if this was happening before my screen was replaced by Apple a few months ago. It definitely did not happen before upgrading to Lion.
    I am hoping you guys can help, otherwise I suppose I will be calling Apple and see if they can figure it out. I am tired of this!
    Thanks,
    Robyn

    I'm having a similar issue. I put my screen to sleep before I go to bed, next day, the computer is frozen, but still on since I can detect heat from the top vent.
    I've checked memory for any errors (5 hours of testing) and removed any system extensions. Still gets frozen.
    I did attach an old USB mouse just to wake it up when it loses connection to the wirless bluetooth devices. I've been able to wake it up from this condition a few times.
    I will keep investigating. My iMac is 1 month old, 27" i5 quad core.

  • I moved to Mavericks and now my imac doesn´t recognize my Seagate Goflex external drive.

    why my imac does not recognize my Seagate  Freeagent goflex after upgrading to Mavericks?

    Luke 1248 First welcome to the discussions.
    If the Toshiba worked before the upgrade it will work again.
    First thing I would do is Unplug it the go to your Black Apple and make sure that your Software is UP TO DATE.
    Restart your computer and then Plug in the Toshiba again and see what you have.  If it still doesn't work Go to Toshiba's Web Site and see if they offer a New Driver for there Product. I hate to say this but Apple sent the Maverickks Operating System to All of the SoftwareDevelopers to make sure there product worked with the different periphrials and softwares.
    Some are a lot faster at responding then others, and naturally all users try to blame Apple on there products or Software not working.  The fact of the matter is it is those that have made the software and different periprials who are to blame for sitting on there hands.
    Come back and tell me if this worked for you.
    Cheers

  • My iMac doesn't recognize by usb keyboard since I installed security update 2015-002

    I installed Security Update 2015-002 on my iMac and since then it doesn't recognize my usb keyboard (I'm typing this with a bluetooth keyboard). I rebooted, unplugged and plugged back in the keyboard all to no avail.
    My system:
    Yosemite 10.10.2
    Mid 2011 iMac 27"
    3.4 GHz i7
    16 GB RAM
    Keyboard: Apple extended USB
    Any help would be greatly appreciated.

    Mine works okay.
    Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one. 
    Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
    Isolating an issue by using another user account
    Try booting into the Safe Mode using your normal account.  Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear and again when you log in. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don’t do them all at once.

  • Please help: iMAC doesn't recognize TC.  Amber light flashes continuously

    This is my second day trying to install Time Capsule. Some background: I have an Arris brand Comcast cable modem. Internet service is fine when I connect the modem directly to the iMac, but not when I run it through Time Capsule. Air Port utility scan comes back saying it can't locate a wireless device. I've double and triple checked all cable and power connections. In addiion I've installed and reinstalled the Time Capsule software, with no effect. I also followed the following steps:
    1. Unplugged the power cable from the TC
    2. Unplugged the cable modem and hit the reset button
    3. Waited more than 2 minutes
    4. Connected ethernet cable to modem; and to iMac
    5. Restored poser to modem
    5. Restored power to TC
    Still no effect: iMac doesn' recognize TC
    I also bypassed the modem and directly connected the iMac to the TC. Light continues to flash amber. I also turned on Time Machine from the dock. Predictably, I got an error message that the storage device oouldn't be found.
    What else can I try? Should I reset the Time Capsule, or will this just foul things up even more? Thanks.

    you need to call your ISP and have them release the DHCP lease on the mac address of your PC and allow the mac address of your TC to join the nestwork.
    You PC 's mac address currently has the DHCP lease.

  • Anyone knows what do do when iMac doesn't recognize any USB or Bluetooth?

    Hello,
    if anyone can help, please. my iMac does not recognize anything I plug into the USB ports in the back. I can't use any keyboard or mouse or track pad. It does not recognize any bluetooth such as magic mouse, wireless keyboard or track pad. When I plug in an older keyboard or mouse it does not see it at all either. don't know what to do. Can't do anything on the computer, which otherwise seems to be working fine, except everything I was using is frozen on the desktop. any advise?

    Zap the PRAM and Reset the SMC, then try again.

  • IMAC doesn't recognize my Canon GL2 camcorder any longer ?

    I am using a 24 inch Imac with a processor 2.16GHZ intel core 2 Duo running Tiger 10.4.10.
    I am using Final Cut Pro version 5.1.4
    Up to the present time I've been able to use my Canon GL2 Camcorder for downloading. Suddenly, for no apparent reason, my Imac doesn't boot up properly when I have the Canon turned on. My 3 external drives don't show up on my desk top unless I turn off the Canon camcorder. Obviously, when I launch Final Cut Pro and attempt to log and capture, the viewer comes up with the message, "No Communication" Interestingly enough, when I connect my Panasonic DVX 100B camcorder to my Imac,it works perfectly for downloading. In addition, I have the exact same Imac in a 20 inch screen running the exact same operating system and exact same version of FCP. My Canon GL2 works perfect on this Imac. Can anyone help me solve this problem. I would be forever grateful.
    Henri

    Did you have other devices connected to your old iMac while capturing? If not that's why it was working.
    One of my cameras is a Canon and besides MacPro and MBP I have also an old iMac. It never worked with external drives connected for the very reason I explained in the link I sent to you.
    Canon FW cameras are just likely to mess up with other FW connections on the same FW bus.
    Best,

  • My imac doesn't recognize my HV30

    Just bought a canon HV30 and Final Cut Express. When I connect the HV30 via firewire to my imac and turn to play nothing happens. It is only recognized if imovie is running.
    Is there a setting that I'm missing.
    I also have the same problem with my Powershot G7. My imac will only recognize it when iphoto is running, but I by-passed that problem with a card reader.

    Change your Easy Setup to an _HDV-Apple Intermediate Codec_ that matches the cameras output.
    Restart FCE.

  • Imac doesn't recognize external monitor but was working

    i had my HP monitor (HP 2011x) connected to my imac for about three months and when i went to move my monitors and imac to clean my desk, my imac no longer recognizes the monitor.  all i did was shift the monitors to the left w/out unplugging any cables. 
    i've seen multiple threads about the same issue where the external monitor is no longer recognized and the majority of no solutions.
    has anyone come up with a solution to this? 
    i restarted in safe mode to try and connect - no joy
    i cleared the pram - no joy
    any ideas?
    thank you.

    thanks man ... i might just do that.  it is just aggravating b/c this problem seems to have been around for a long time (based on all the support forums threads started about it).
    i went to the apple store this afternoon and verified my thunderbolt to hdmi was working and sure enough it was.  i talked to two staff members there and they were equally as clueless why the external monitor is not being recognized via the cable.
