printers HP 8500 (A910a): print head for white stripes of printing cyan horizonnally

• Printers HP 8500 stopped printing

  I use Mac Book Pro with current OS (10.6.6) software to print wireless. The printer has stopped printing and scanning. (It works well and just started to act up today.) Obviously I did something that caused the problem but I don't know what.)

  It seems to be properly installed. When I send to complete a print job seems to accept the work it shows that 1% then closes in response.

  I tried to completely uninstall the printer and all HP - including the scan software software.  I did a software update from Apple and no update has been found/necessary. Still no printing/scanning.

  Any help will be appreciated. Thank you

• Cannot start the HP printing software (HP OfficeJet Pro 8500 A910a)

  Hello

  When I double-click the icon of the HP software on my desktop behavior strange results. Nothing opens and my computer behaves erratically. After a while I get the following error messages:

  instancefinderdlg.exe

  werfault.exe

  Then after that - my computer restarts so all by himself. But not a complete reboot - it just goes back to the initial logon screen and I get my password from Windows and displays the desktop.

  I am running Windows Pro 8.1 (64-bit). The printer is set to work wireless.

  After doubleclicking on the HP software icon and wait for the software to open, as I mentioned above, one thing I tried was a ctrl-alt-del and open Task Manager. I checked the services running, and there were multiple instances of a service life of HP (I not only remember the name but there seems to be dozens of the same HP service running).

  I also completely uninstalled all HP software use Revo Uninstaller and then reinstalled the software / driver for the OfficeJet Pro 8500 A910a - but this package did not make a difference; exactly the same problem occurred again.

  It happened only in recent days. Before that, I could double-click the HP software icon and open normally and I was able to check the settings, ink levels, etc. Interestingly, the printer seems to always work well - I can print in Word, print photos from Lightroom, etc. Just, I can't open my desktop HP printing software.

  Any help would be greatly appreciated. Thank you!

  Hi jedasa,

  I guess you can start to feel frustrated. I did some additional research and would like to try a few things. I want to delete the printer Assistant icon, open devices and printers, right-click on your printer and choose open. In the window that opens, please right-click on the Printer Wizard and click on create a shortcut. Now we can go to the desktop and see if it will be open from there. The icon will now by HP in a blue circle and say HP Printer Wizard below (see image below).  If it opens and works, we use this going forward, but if it does not continue with the steps below.

  

  1. Hold down the Windows Logo key ( ) on the keyboard and the 'R' to open the dialog box run, type %temp%
  2. Delete all files and folders in the temp folder. Choose Skip if all pop ups seem to say all files cannot be deleted
  3. Unplug the USB cable (if connected), open programs and features, click Editor (all HP software will be together now) and uninstall all software associated with the printer. You fill find the basic driver, study for improvement of the product, HP Officejet 8500 help. Be sure to do not uninstall other HP software, especially if your computer is a HP computer. I generally use the date as a reference. Printing software would have all been installed on the same date.
  4. Once the uninstall is complete, reboot the computer
  5. Follow these steps to reset the registry settings and options for Windows Installer.

• Help! 8500 a print report has white horizontal lines through the blocks of Magenta and Orange.

  I SOLVED MY PROBLEM BECAUSE OF THE HELP I RECEIVED BELOW.  MY ORIGINAL MESSAGE FOLLOWS.  BE SURE TO SCROLL DOWN FOR THE SOLUTION!

  Please see the focus 2 below: I read all the posts here and of course I cleaned the printhead of many many times.  It is almost the worst lines now.  The printer cartridges are all full, and I also turned the printer on and off the power, etc... . Thus only line ACEs and calibtrated a bunch of times.

  Is there anything else I can / try?  Is there something else to clean inside and the dust that creates streaks?     Doesn't seem wise to call and pay for this service.

  None of my impressions with the graphics seem to be good all of a sudden and he is hurt and slow down my business – do I have to buy another printer?

  Help!

  

  Is the a page of print head cleaning blocks magenta and red lines? This means somehow magenta ink is not put on paper on these lines. Because this is not the whole of the region, it's not magenta ink came out. Must be on the printhead nozzles is obstructed or somehow blocked. It is display in the fine lines on the quality report page you have posted. Broke the thin vertical line shows the nozzles at these locations are not belittling inks.

  If the clean print head does not resolve the problem, you may need to replace the print head.

  The 8500 has 2 print heads, one for the black and magenta/cyan. This page show you more about clean/replace the printheads on 8500 a: http://support.hp.com/us-en/document/c01615896

  In this page, there is a photo showing the printhead with the wording: "nozzles - do not clean", it is because that manually clean nozzles could easily damage the print head and make things worse. But if anything the problem and replace the print head, you can try to clean the area of the nozzle with a fluffy, wet with warm water. But when a printhead issue, when the "clean printhead" functioin does not help, I strongly recommend to replace the print head.

• My Officejet Pro 8500 wireless won't all print cyan?

  I have been using this printer for about 4 years. A few months ago, he stopped printing cyan and I'm now talking to her. I ran the clean print heads, etc. and cyan has not come at all. This is after trying a former and new officer, print cartridge Cyan HP. Help, please.

  I have the 8500 institutions and experienced a similar problem. I managed to sucessfully troubleshoot. I replaced all ink cartridges that did not help. I replaced the two print heads and now it will be printed as the day, it was new. Be sure to shake each printhead for at least 10 seconds prior to installation.

  Printhead part numbers are listed below.

  Yellow and HP 940 Black Printhead

  Cyan and HP 940 Magenta print head

  I won't you be kidding the print heads are expensive. ($62.00 each), but they should solve your problems.

  Try them, replacement print heads are under warranty if you really have nothing to lose.

  Good luck.

• HP officejet Pro 8500 a: HP officejet Pro 8500 has driver software for Mac OS v 10.10.2

  Dear Sir

  could you please provide me with the HP officejet Pro 8500 (A910a) a software driver for MacBook pro (OS X Yosemite v10.10.2) everything in is not available on the site.

  Kind regards

  Hello Sabrina,

  Welcome to the HP Forums.

  I see that you need the software and drivers for your printer on the Mac 10.10 operating system.

  The reason why you are not able to locate is simple because they are not available at this time.

  I have a suggestion that you can try.  Please click on the following link for HP v3.0 for OS X printer drivers.

  This driver will give you the possibility to print from your Mac.  You can use the scan to Apple for any analysis software that is already on the Mac.

  I hope this information is useful and if you have any other questions, do not hesitate to ask.

  See you soon,.

• How to put a heading for a group of controls without line below the title text?

  Hello

  Is it possible to write a heading for a group of controls and indicators made by "chiseled online", such as the chiseled line remain invisible under the title text and remain visible everywhere else? For example, the titles 'Printer', 'Range', 'Copies' and 'Zoom' in a Microsoft Word form in the PDF file attached. Note that there is no line under the title text and there is no text box surrounding the text of the title. I want to have that kind of title for the Group of controls and indicators in a GUI of my LabVIEW application.

  Any help will be appreciated.

  Thank you.

  Any label you use as long as you COLOR IT CORECTLY. Use the background with transparent border color... just set the boxes of color as shown.

  

• HP series 8500 909 printer offline

  I have a new HP 8500 wireless printer. Setup was easy and the printer and wireless worked well. However, after some time, Windows 7, says that the printer is offline. There is no way to reconnect to the printer, even if is not in mode 'sleep' and wireless Internet works fine. The only solution I've found is that whenever the printer offline message, I need to go to the control panel > printers > and remove the HP 8500 and then reinstall it by selecting "add a printer". Needless to say, it is a pain. Anyone facing this problem and find a better solution?

  If it looks like your question:

  After you install the product on a network, you turn off the computer, and then, and the product loses functionality. The product is no longer prints and disappears from the icon of the product in the menu devices and printers in Windows 7 (64-bit).

• DeskJet F4280: White stripes (no printing) - F4280

  Horizontal white stripes (no printing) - seem to be in the same location on the page when they occur.  'Only' occur when printing from a Microsoft Works word document or spreadsheet, or copy a page perfectly printed.  Test the printer Windows page ok being IRS forms and instructions were published recently.

  @PapaPhil,

  Welcome to the HP community! I wanted to stop to my suggestions to help with your problems. If I understand the questions, print outs of Microsoft Works and when making the copies of your Deskjet F4280 all come out with horizontal white bands on them...

  As copies are a feature that doesn't involve all the computer, it is a sign of a hardware problem. You can try a power reset (see below) and to ensure that the printer is connected directly to a wall outlet, avoiding the power and surge arresters bars.

  Try to make a copy again from the front of the printer and if the horizontal bands to continue, you will need a new unit and I would say to contact HP to see on your next printer options.

  If you find that copies work fine, please let me know and we can move on to troubleshooting software because it will show us that the printer itself is OK!

  Hi @robgit,

  Please check back with the results of your efforts.

  You may need to configure the automatic duplexer in the HP printing software.

  Discover sone of the procedure described in this document - printing on both sides of the paper (duplex) (OS X). Note: This model of printer supports automatic duplex printing. Scroll down to "How do I duplex automatic if my printer takes in charge?" in the FAQ section.

  Please let me know if it helps.

• Get a fixed header for Mobile site?

  Hello

  I'm trying to put in place a fixed header for my mobile site. I have tried several things and continue to operate in the same question. Although I have not tried to display on another mobile platform other than iOS 8.1, but the issue I'm having, it's that my address bar will not collapse when I defined in the page scrolling effect. So what ends up happening, is that I'm losing the top of my page, because the address bar is always visible. Is there a work around?

  I have attached a picture of my site and another site with what I am trying to accomplish.

  Thank you!
