Photosmart c4280 scanner "USB not connected" to Mac running 10.9.5

I've combed this forum and others and tried all the tricks.  I can print and copy, so there's no USB problem.  I've turned it all off and rebooted, downloaded an update, removed and re-added the printer, plugged, unplugged the USB and power cords.  I've tried using image capture but it says it is not connected to a scanning device.  I've reset the printer and uninstalled, per the directions in another thread.  Now when I add the printer back, the C4200 series is not an option for software, since I deleted it (and software updates on Mac of course detects no updates available)  so the default is "Generic PCL Printer" and of course, it still says the USB is not connected.   What now?  Thank you!

Hi @techtrampled,
Welcome to the HP Forums!
I understand that you are getting a USB not connected error using your HP Photosmart c4280 on Mac 10.9.5. I am happy to help!
I would recommend to go through the steps in this printer is offline guide, 'Printer is offline' Message Displays on the Computer and the Printer Does Not Print: Mac OS X.
Hope this guide helps, and have a wonderful day!

  • On my photosmart C4200 series printer, error message says USB not connected

    I have a hp photosmart C4200 series it's saying the USB not connected. I made sure all connections were secure and still same message. I unplugged it and then plugged back in at tower and printer, still same. I changed out cable, still same problem.  Is there anything else I can do aside from buying a new printer? Thanks, Jenn

    Hi @jennirvinpest,
    Welcome to the HP Forums!
    I noticed that you are getting the error message that says your USB is not connected with your HP Photosmart c4200 series.  
    For further assistance, I will need some more information:
    The Product/Model Number of your printer. Follow instructions in this link. Finding Your HP Product Model Number.
    If you are using a Windows or Mac Operating System, and the version number. To find the exact version, visit this link. Whatsmyos.
    If the printer is able to make copies.
    If the power cable is plugged into a surge protector, or directly to the wall outlet. Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector. This applies to Inkjet printers as well.
    Thank you for posting, and hope to hear from you soon!

    Mac. Yosemite- Illustrator CS6 and CC both crash right after starting. Have Suitcase 6 (not 5). current Wacom drivers. Tablet not connected to Mac. Anyone else experiencing this?

    Hi,
    Scott Agnew,
    Please check if there are any updates pending for Suitcase fusion and Illustrator.
    You can also try resetting AI preferences.
    User Library/Preferences/Adobe Illustrator [#] Settings
    Rename Adobe Illustrator [#] Settings to old Adobe Illustrator [#] Settings
    User Library/Preferences/Adobe/Adobe Illustrator/Version[#]
    Rename Version[#] to old Version[#]
    Access user library Access hidden user library files | Mac OS 10.7 and later
    Do you get any crash report. Look if it says anything for Wacom or extensis?
    Thanks,
    Nikhil Gupta

    I have Acrobat 9 and I get a message saying that "Either Scanner Driver is Not Installed or Scanner is Not Connected" when trying to scan from a document. This happened on two separate scanners with updated drivers. I already tried rebuilding my Acrobat installation to no avail. I'm using Windows XP.

  • MacBook Air Camera is not connected after mac OS update

    MacBook Air Camera is not connected after mac update
    I have a MacBook Air OS X version - 10.9.4 . I updated my mac 1 week before but todayI check that my mac in built camera is not working Even I try to check in this thing in all the apps. Please provide  the way how to sort out this issue asap.

    Use the suggestions here: http://support.apple.com/kb/HT2090
    The SMC reset often fixes your problem.
    Be sure you follow the instructions for your particular Mac model.
    If your problem continues, restart Mac.  Then download and install OS X Mavericks 10.9.4 Update (Combo).
    If that does not correct the problem, reinstall Mac OS X.
    If nothing else works, contact your Apple Service provider or Apple MacBook Support for help.

  • Usb not connected 4280

    i can copy but when i scan it says USB NOT CONNECTED but it is. i have had this printer FOREVER  but recently had windows 8 installed.  how can  i scan and no im not going to do an uninstall at this point.  i scanned manually recently but cant remember how i did it. 

    Hello @kirksandiego and welcome to the HP Forums, I hope you enjoy your experience!
    I see you are experiencing issues scanning. I would like to help!
    I'd suggest removing the cartridges and performing a power reset.  Disconnect the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug the printer back in. Ensure you plug the printer directly to a wall outlet. Make sure to bypass any sort of surge protector or power bar.
    I would also recommend downloading and running the HP Print and Scan Doctor.
    Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums!

  • Ever since I installed MAVERICK, nothing now works, Flash Player won't run, printer works but scanner will not and the computer runs so slow.  Any help anywhere?

    Ever since I installed MAVERICK, nothing now works, Flash Player won't run, printer works but scanner will not and the computer runs so slow.  Any help anywhere?

    wqn02h, first thing I would do is use Disk utility to repair permissions. Once this is done. Make sure you have the latest versions of the software you use. Also, check the manufacter of your printer/scanner for updated software. If they don't have updated software there are 3rd party alternatives that will work.

  • C4380 Scanner is not detected on Mac Snow Leopard (10.6.8), by USB or wifi

    Hello,
    Working with a MAC with Snow Leopard (10.6).
    Suddenly longer able to access the printer via WIFI. Reinstall the software and configure the network went back to the printer.
    Now the printer is working correctly by USB and WIFI, but the scanner is not detected.
    Can you help, please?
    Thank you very much.

    When you re-downloaded the drivers and software, did you get the FULL FEATURE drivers?
    Did you download this from the website or from the CD?
    You can run the print and scan doctor, and check the results.

  • USB Barcode Scanner (Adesso) not reading on Mac Mini

    My friend bought an inexpensive USB bar-code scanner (Adesso Nuscan 1000U), which they said should work fine in OSX, to use on his Intel Mac Mini, running Leopard 10.5.4.
    Model Name: Mac mini
    Model Identifier: Macmini2,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 4 MB
    Memory: 1 GB
    Bus Speed: 667 MHz
    Boot ROM Version: MM21.009A.B00
    SMC Version: 1.19f0
    Serial Number: YM7309F0YL2
    After plugging the scanner directly into his computer, it was acknowledged to be an "non-standard" keyboard...
    - the "Keyboard Setup Assistant" window popped up, and he hit continue (instead of closing the window)
    - "Identifying Your Keyboard" came up, and he had hit "z" on his main keyboard (a mistake, he knows now)
    - said scanner will not "print scanned data to screen" as it ought to
    - scanner "goes to sleep" after it scans it's first barcode - does not 'wake' until unplugged and re-plugged into Mini. Never does this on other machines.
    - scanner works perfectly on three other Macs running Leopard (same version on all four machines), both Intel and G4 based
    - I have repeatedly trashed the "com.apple.keyboardtype.plist" file in hopes of re-setting his computer to read this device properly, with no luck - but each time it's trashed and we plug in the scanner it pops up the "Keyboard Setup Assistant" window, which we simply close... like on the other test machines.
    I know it's not the scanner itself, as it works fine on all other systems with the same OS. We had simply skipped the "Identifying Your Keyboard" prompts and closed those windows and the device merrily scans barcodes and prints them to any text window - as it should.
    Is there a chance that some difference in the Mini hardware would somehow not allow this device to work properly with it? I'm completely stumped. Thanks for any assistance!!
    -ant.

    Not to be rude or contrary, but if you read my entire posting, the same unit (usb scanner) works successfully on at least three other machines with different processors running Leopard.
    To further elaborate:
    • manufacturer has been contacted and in touch - they have no idea why it doesn't work on mini
    • no software or drivers - none needed for all the other machines
    • my workaround (deleting .plist file) did nothing except prompt
    the computer to ask me what kind of keyboard device it was (none)
    Thanks for the effort... and the welcome.
