• HP Officejet Pro 8600: Recently a fax pops up when I try to print photos and the picture does not print

  We have a printer all-in-one HP Officejet Pro 8600 operating from a desktop HP with Windows 7. Recently, in the last two weeks my wife told me, we cannot print photos. The documents appear to be printed without a problem, but when trying to print a photo we get a window titled 'Send Fax - HP Officejet Pro 8600'. We have never used or even hung fax capablitly since we have owned this printer (maybe 2-3 years). All of a sudden, this window is displayed when we try to print a photo and the photo does not print.  I can't tell you that my wife did not hit accidentally a wrong button somewhere down the line, but she says she does not. I tried to attach a screenshot of the window, but for some reason that it does not take it. It's probably something very simple, but technically challenged myself, I can't understand. Help, please.

  Thank you

  Vince Pellerito

  Print picture of what program?  Some programs to keep their own default values for the printer.  It seems that the default printer for the printing of the photo program has been set to Fax.  Try to open the program, select the Officejet Pro 8600 as the printer rather than the Officejet Pro 8600 fax.

  Sometimes a problem with Firefox can be a result of malware installed on your computer, you may not be aware of.

  You can try these free programs to search for malicious software that work with your existing anti-virus software:

  • Microsoft safety scanner
  • MalwareBytes' Anti-Malware
  • Anti-Rootkit utility - TDSSKiller
  • AdwCleaner (for more information, see this other AdwCleaner download page)
  • Hitman Pro
  • ESET Online Scanner

  Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP, if you do not already have one.

  More information can be found in the article troubleshooting Firefox problems caused by malware .

• Printer and driver; When I try to add Epson Stylus SX415 he does not appear in the list of printers

  My Epson Stylus SX 415 does not want to play with my windows 7. it did before. Printers on my computer, it has a 410 SX that I can't remove for any reason any. When I try to add SX415 he does not appear in the list of printers of ideas?

  Have you tried to download and use the driver provided by Epson for this printer?

  Windows 7 will install the drivers for some printers, but not all, and in many cases, the software installed does not have full use of the features of the printer.

  Remove printers from the list in the devices and printers sometimes takes awhile, and even a re-boot.  Uninstall will fail if there are no printed documents in the print queue in Windows to be printed.  You must delete this queue first.  There is a troubleshooting printer built into Windows 7 that can help too.

• Are there problems with Microsoft 7 and Frontpage 2002? The system shuts down when I try to add a hyperlink.

  The system shuts down when I try to add a hyperlink.  The hyperlink insertion page opens.  But when I try to click on the link that reads "Microsoft Frontpage has stopped working.  A problem caused the blocking of the program works correctly.  Windows will close the program and notify you if a solution is available. »

  Edited to add: if I type in the hyperlink, it seems to work.  But in the past, I just clicked it.  But now when I click on it is when she stops.  Strange.  Did not this on the Vista computer.

  Hello CaptainKAG,

  Thanks for posting on the Microsoft answers Forum.

  I recommend you post in the Forum Office where this problem is related to FrontPage 2002. We can install on Windows 7, but is not fully compatible, so some features may not work properly. Office 2003 and Office 2007 are fully compatible with Windows 7.

  Hello Subocz E M.

  Thank you for using communities of Apple Support. I see that you had problems adding pieces and turn off Genius. I know how it is important to be able to add music to iTunes. I'm happy to help you.

  Since you are being invited to turn off Genius, you can add music, please use the following information to resolve these two issues:

  Turn on or off the Genius

  If iCloud music library is enabled, you cannot disable Genius.

  Choose file > library > Genius (toggle Genius).

  Turning off the Genius Genius Genius Shuffle shuts and and the Genius Mix.

• Using script - library locked when you try to add the file to it

  Hello

  I'm just a simple script that I can run with my engines of the action, so if I add new enum values I can create new wrappers quickly. I am able to create a new VI on disk, but when I try to add the the VI to the library, I get "error 1562: library, or the specified project is locked." Just before adding the article, I tried to adjust the State of the library "Not locked", but has not been the tower.

  Directions to see the error:

  Open attached zip file

  Open 'Engine.lvlib Action '.

  Run "Script - Create Wrapper.vi.

  Please let me know how to get around this, I thank you,

  Gregory

  There are two reasons at least a library locks: 1) something he possesses is running, 2) is open in two or more instances of the application.  (This applies to classes too.)

  I started a project and took your scripts out of the library (to avoid the #1) and then open your Library Reference by path in your script, be sure to include the reference of the application (to avoid the #2).

  Works now.  (With the exception of the Init.vi but you mentioned earlier that you knew about it. But point 1 and 2 of article work fine.)

• I get "access denied" when you try to add the component 4543BD

  I get "access denied" when you try to add the 4543BD to my diagram. This component has been added since a previous version. I use Multisim version 12.0.0 student edition.

  Hi Diarra,

  I checked my database and the 4543 isn't in the student edition. If you open a drawing that was created in a version more recent as the education edition and copied the part to your database, when you place this part, you will get the access denied message.

  Attached is a diagram with the part, you can open it and build you circuit around it.
