activation of printing caused wireless printer HP Multifunction Pro L8770 to freeze all the time.

Product: Range of HP Pro L8770 multifunctional printers

Operating system: Windows Vista

No error message; the printer display screen froze after that I enabled printing on a printer wireless by entering the password for my Internet.

Now, the wireless on the front panel light shows a blue light, but printer is therefore more receptive to requests from the computer (printing, scanning, etc.), and all the keys on the front panel of the printer is no longer arouse a reaction.

Unplug the printer power cord then by him restarting does not reset the problem.

I have no way to disable wireless printing.

HELP please.

Thank you.

You will need to perform a partial reset to try to put the printer back to factory settings.

To make a partial reset:

  1. Make sure that the printer is turned on.
  2. Pull the power cord to the rear.
  3. Pull out the power cord from the wall.
  4. Wait 30 seconds.
  5. Reconnect the power cord, but do not connect the printer.
  6. Press and hold the 3 and # buttons on the printer.
  7. While maintaining the 3 and # buttons, plug in the printer.
  8. As soon as you see lights up, release the buttons.

That should put everything back at the factory.  Once you have done and get the printer up, be sure to update the firmware.  The firmware update, you can try installing wireless if you wish.  It should fix what caused the problem, and if it isn't, you have the steps for a partial reset to fix.

  • with these changes, I can only print a page of print preview ability has been removed I use it all the time when you want to print something on a Web site

    When I was on a website and I tried to print a page, it allows to be a tab that says "FIREFOX" in the upper left corner of my screen, I could click on that tab and I had several options, one was "print" and "print preview". All the time, I use the Preview button before printing to see how the page would look like when I was feeling and how many pages there are. I could then choose to print all or part of an article and adjust it to what I wanted to print. I don't have this tab in the upper right corner. A tab for "open menu" is now in the upper right corner, however, in this menu is only a button 'print '. There is no option for "print preview" and so I can't address that I want to print. I could also adjust margins, etc. of a tab from the view, I can not find too. I really hope there are always options and how I find, where are they located?

  • Re: Satellite Pro A300-1EA - wireless connection, drop all the time

    Hi, I have a problem with my wireless connection fall all the time on my Satellite Pro A300 1EA.

    It happened earlier, but I've fiddled about a little with change of drivers and the removal of the connection settings for the registry and it then worked fine for months, until yesterday.

    There were several updates for Windows installed yesterday, but none of them have been updated driver for the wireless card, and they don't look like they should cause problems. The fact that the problem happened before makes me think that the updates can be anything to do with it.

    I use the * Intel PRO/Wireless 3945/4965/5100/5300 * for Vista 32 - bit version 12.2.0.11.3 drivers from the Toshiba download page.

    Other computers on the same access point have no problem, so I think it is specific to this laptop. The connection speed is normally 6 Mbps, but I cannot even check e-mail now without the abandonment of the connection.

    Laptop will be thrown against a wall soon if no one can help you.

    Thanks in advance.

    Edit: I've already made sure power settings are at maximum to the WLAN card, even if on battery, or what power management.

    Hello

    Have you tried to use the Windows System Restore feature? After that your WLAN should work fine again.

    In addition, I can recommend the latest WLAN driver in the Intel page, it s version 12.4.xxxx. I installed the driver on my Qosmio laptop and don t have any problems with it: [www.intel.com].

    If you have any other questions, please let us know!

  • The wireless on my Aspire 5535 is all the TIME

    The wireless on my Aspire5535 is all the TIME, it goes out not when the wireless button is pressed, instead, I get a message on the screen "No. Wireless Device" even if there is a card physically installed. Press the bluetooth button, and the message is 'No Bluetooth Device'. I changed the Atheros card and installed newer drivers have also replaced the 'launch plug. I still get the same problem. The machine works well with a dongle, but I would use the USB port. Should I buy another wireless card instead of 'G' band go to a bunch of "N"? As there is no update of the Bios I can't do anything with the Bios, (thinking that it is may be damaged). Should I buy a Bios Chip?

    or someone has any ideas on how to solve my problem.

    Greetings to all

    Barry D

    Hey Jack,

    Thank you for all your help and suggestions. I'll take the machine except maybe find the problem, but for now I'll stick to the dongle / eathernet, I usually at home, when to use the system of 'Home Plug' which I find better than the dongle. Once again thanks a lot for your help

  • I want to activate the outputs audio multiples to be active, so I don't have to wear my helmet all the time, or need to disconnect anything to the speakers.

    Pretty simple question really. I want to activate the outputs audio multiples to be active, so I don't have to wear my helmet all the time, or need to disconnect anything to the speakers. I checked the 'sound' thing in the Control Panel, but the enable option is not letting actually work. So if I want friends to hear my video games or something else, I turn on my speakers and they can hear it now.

    Thank you.
    Windows 7, 64 bit.

    Audio original tittle: multiple

    Windows does not support this. This is handled by the device drivers or hardware - if they don't support the outputs multiple, you can try the search for an alternative solution.

  • Printer HP Officejet Pro 8600 Plus works but the Scanner does not

    I recently bought a Toshiba laptop with Windows 7 Home Premium operating system.  My previous laptop is a Toshiba also upgraded to Windows 7 Home Premium operating system.  I have a printer HP Officejet Pro 8600 more all-in-one printer.  The printer/scanner works fine with my laptop more older but with the new laptop that I can't get to the printer.  I am not able to get the scanner to work.  I reloaded the software several times but the scanner still does not work.  The scanner works fine with laptop more old, even if it has the same operating system.  I get an error message that says "Scan of the computer is turned on.  You can start a scan from the printer.  Your computer is not listed as an available computer control panel of the printer.  If please restart your printer and try again. "Can anyone help with this?

    Hi ranjisamaraweera,

    Even though I'm MVP I represent Microsoft or speak. If I can and will speak
    as I think.

    The proper functioning of the printer and Scanner is the direct responsibility of the producer of material
    and no windows. There are hundreds of these devices that work correctly on Windows 7 if
    those who don't have no drivers and other interfaces which are not compatible to Windows 7 should be
    written correctly. Of course many older devices are not supported by their creators for later
    Versions of Windows. Microsoft passes but does not write drivers and interfaces
    Printers and Scanners need to function properly. So, the manufacturer and no one else, is totally
    Manager to see if there are interfaces and appropriate drivers.

    Many device makers do not write new drivers and interfaces for older hardware because either
    they cannot support the new methods or because they want to sell new hardware.

    Personally, I don't think that Microsoft is lying because they also say that device manufacturers have the
    Omos unique to provide the necessary compatible drivers and interfaces.

    I hope this helps.

  • OfficeJet Pro 8500 has left black print all the time

    Just recentily my printer prints as if it was almost out of black ink (text has missing parts and streaks).  If I have a third level cleaning I can finally return to normal black.  After a few printed pages, it begins printing with portions of the rear lack again.

    When I do the cleaning of the print head of all colors but black shows correct in the first and second level cleaning.

    All the ink cartridges show good levels.

    Show the print heads.

    My question is my back ink cartridge would be haviing a power problem the ink in the print head?  Is there something in the third level of cleaning that would make the flow of the ink properly for a short time?  This problem appeared after I replaced the black ink, but not immediately.  I have always used HP ink cartridges in the printer.  I'm tempted just ro replace black with another cartridge to see which takes care of the problem but didn't do it if anyone else had the problem and found a solution.

    Just tried to replace the cartridge with a new back and I'm having the same problem with it.

    Hey there 3R.

    Thanks for the images and information! Which really kinda helps.

    I notice that the black is better temporarily by the third cleaning, and also consider other colors, I have noticed them all degrading by the third cleaning. According to me, this looks like a problem with the two print heads, now I can visibly see Printing outs. The yolk is less apparent among peach and green and the cyan and magenta also show a lower quality tone.

    Replace the print heads cannot guarantee a fix.

    I always suggest calling HP to see what are your options for a trade.

    I hope that my opinions and suggestions helped you some.

    All the best,

  • BlackBerry Smartphones BlackBerry keeps beeping all the time - just beeps when the connection with the carrier is active.

    Gentlemen.

    I have a Curve 8900 with the 4.6.1.133 (Platform 4.2.0.85).

    This unit maintains a beep every 10 seconds, I tried to remove the battery when the BB was on, wait a minute, put it again.

    I looked at all the configurations.

    I Don t no the slightest idea and wanted to throw it in the window.

    Any ideas? Advice?

    NEW INFORMATION. The device stores only beep if the wireless connection with the carrier is active. If it s off the beeps stops. I m using Claro to the Brazil.

    Camilo

    I found the solution. This is a bug beetween the network operator's SIM card software and the BlackBerry device. It s already solved. I had to follow certain steps to enable and disable a specific feature of the network operator and wait a dialog box confirm my operation.

    The beeps comes with the dialog box, but the apears only dialog box if you are in a specific screen of the blackberry. If you are in the home screen, it will not appear and you hear the beep.
