I have flashing lights and impossible to turn on or off.

I have flashing lights and can't turn on or off.

Thank you for your help.

Hi P a-t

I understand that you have lights flashing and the printer will not turn on or off.

I'd do a power reset to see if that will solve the problem. When the printer is still lit, disconnect the power cable to the back of the printer, if the printer has external power supply with a detachable power cord unplug for 15 seconds and reconnect it. Then, disconnect the power cable from the wall outlet. Wait 10 seconds and reconnect the power cable to the wall outlet first, then the back of the printer and turn on again.

Make sure that the printer is connected directly to a wall outlet. (do not use a hub or a surge protector)

Please provide the following information so that I can better help you.

What operating system do you use?
Here is a document to your operating system Windows.

Here is a document to verify your operating system Mac.

Please provide the name and the product number of your printer.

How is the printer connected? (USB, ethernet, wifi)

    Hi neuserivergirl,

    1. have you made changes on the computer before this problem?

    2. which version of the operating system is installed on your computer?

    What version of the operating system Windows am I running?

    You can disconnect the power cable from the plug, and then try to turn on or off.

    It seems to be a hardware problem, I suggest you contact the manufacturer of the printer for assistance on this issue.

  • C4680 flashing light and sound with Mac OS x 10.6.8 and USB connection

    Printer and light beeps flashes when asked does not print.

    When I opened the door of the cartridge, ink cartrideges will not move.

    Power levels when I check in the printer utility are ok.

    When I unplug to reset then reconnect to power, by flashing and beeping resumed. I unplug the night so I can sleep, and in the morning when I plug it, it beeps and flashes.

    Have tried to reinstall the printer on the Mac OSX.6.8 OS. Always beeps and flashes.

    When trying to print, get message the printer offline.

    If I go to system preferences and open the print and fax, the printer finally hiccups, even if beeping, goes to the line and prints.

    After 5 minutes, it starts to beep and flashes again.

    I would appreciate ideas... I worked through this aqppears troubleshooting guide if I search "flashing lights" and printer just keeps beeping and flashing.

    It looks like a hardware problem, I will consider the question more away, but if a sensor is damaged, then that could lead to these issues.

    I would also like to check this site for possible updates:

  • Does not print to Deskjet 3930 flashing light and all of a sudden!

    Hello, newbie here, the first time on this site (it's amazing how this small printer was!).  Had this printer for years (please don't laugh it's how old).  It was printing fine, never a problem with her all these years.  Then all of a sudden, my son tried to print something and the printer turns on, sounds like it is printing from the beginning, but then just blink.  I tried new ink cartridges, unplugging, resetting the print queue, downloading and installing software HP Print doctor.  Nothing.  One day we just fiddled with it by opening and closing top a whole bunch of times, turning on and outside (no real procedure) and voila, it started but then stopped at half way through.  So we opened and closed in on the top and he finished print perfectly!  Then he had no problems printing, but only if you keep printing immediately.  The next day, we needed to print again and back to the same problem.  It will not be printed, continues to add to the queue printing and the green light stops flashing.  What could be?  Please don't tell me to buy a new printer, I have new ink for this printer and I love how small and compact and simple to use.    It of as if there's a thing with it now or something.  Thank you.

  • I uninstalled flash player and impossible to reinstall

    I had problems reading of streaming videos and decided to uninstall and reinstall flash player. I am running XP SP3, so I used the Add/Remove programs and uninstalled. Now, I can not re - install. I passed on the adobe site (http://www.adobe.com/software/flash/about/) and chose to install the drive via Firefox, but it failed and proposed a manual installation. Clicking on this link puts me on the adobe site, but by selecting the download button sends me to a page of advertising for other adobe products and no download occurs. I ran Internet Explore to see if I could download the file and Firefox recognize, but while it shows 'Adobe Flash Player 11 ActiveX"in the list of installed programs, Firefox doesn't know any difference. Any suggestions?

    A virus does not appear to be the problem. I have not been able to install from the adobe web site, but I did a search for the executable flash player downloaded and executed directly. This approach was implemented to me. Thanks for the help.

  • HP Photsmart C7280 - flashing lights and error messages on blue when screen off the printer.

    HP Photosmart C7280 All in One.

    This 3 year printer seemed to install OK when I it connected via a wireless modem/router.

    My turn and Lap Top printed ok for months. They use Windows 7 64-bit.

    Recently when the printer was left off for a few days all its lights started to blink.

    If I disconnect and reconnect it the power and cable modem/router, the printer works ok again until it is turned off.

    The lights will start to Flash.  Also, I'm getting 2 error messages on blue screen when the power is off and the lights are flashing...

    B8SIFE84 blue screen error code still appears, and once I saw the blue screen B3772734 error code appear as well.

    I deleted and reinstalled the device by using the printer software HP correct and downloaded and installed all the relevant printer updates that I can find. The problem still persists.

    Help, ideas or thoughts to the subject of what to do to solve this problem would be appreciated.

    Don't

    Have sussed out.
    Power supply is 'blacktus cactorum cactus. "
    It is unclear when it is off.
    Looks like this is a new printer for "don't" then buy HP shares and buy a 5 year warranty with the new printer.

  • DeskJet f4280 on off flashing light and not cut or answer

    My printer worked many years, but began with the printing of form elongated and defective.  I changed the color cartridge is low and printed an alignment page right after a few tries, and now when I try to scan the page to align cartridges buttons are frozen.  The button scan or resume will not respond and walk / stop light continues to blink.  What should do?

    Looks like the printer is stuck in an error state.  Are there mistakes on the product or simply the lights flashing?

    Have you tried a hard reset of the printer?

    Unplug the unit when turned on

    Disconnect the other end of the power cord to the power source

    * Wait 30 seconds

    * Plug the unit back to

    For example, see the procedure described in the document for the inadmissible printers troubleshooting, found here.

    If you get on the printer and it works, then there are also a document for issues of the cartridge.  The document can be accessed here.

  • BlackBerry Smartphones camera flash lights and blocking unit

    I have the camera set to Auto flash.  Whenever it flashes, it is not just flash - it stays on and blocks the entire system (with the exception of the light).  A battery pull resets the device (including light).  Something about the function of flash is the cause because if the camera does not use the flash there is no problem.  Any recommendations?

    Hi and welcome to the forums!

    Try to open the video camera and using light. All the problems?

    I open the camera, options, change the flash for another option and then save.

    Open the camera again, select the flash option you want and save. Then make a battery

    Pull as shown.

    Let us know how it goes!

    Thank you

    No data will be lost when you do the following: remove the battery while the device is activated.
    Remplacer replace after one minute, let the device reboot 1-3 min, see if the problem is corrected.

  • Satellite A300 - no power light and won't turn on

    Hello:

    My satellite A300 fell off my office. It has been disconnected.
    A few hours later, I tried to turn it on, but does not work when I plug the ac cable lights that turn on normally.
    Ive opened to check if there is nothing broken, but it seems all good.
    What can I do?

    My battery is dead, so I can't do anything with it.

    on the virtual path that is not easy to say what the problem is here, but if there is no reaction and led DC is not on I assume that there is a problem with the power of electronic power supply on the motherboard.

    Visually, everything can be OK, but some connectors are probably damaged.
    Repair (Exchange motherboard) is quite expensive, so I think you should sell it on eBay and get any other machine.

    Satellite A300's beautiful machine, and you can get another A300 used on eBay for about 100-150 Euros.
