HP OfficeJet Pro 7780 Won't connect to computer wirelessly.

The printer worked very well for about three years then it failed to work on the USB cable connection. I connected with a network ethernet cable and it worked for about nine months. Then that quit working. So I connected with a wireless router and that worked for about three weeks. The Wireless Network Test Report indicates the Radio On = PASS, but the Radio Working = FAIL. The wireless wizard never finds the wireless network. Is there a solution or has this printer reached the end of lts life?
This question was solved.

Hi,
The printer wireless card is gone bad that is the reason it says wireless radio not working.the printer can only be used with usb or ethernet.

My HP OfficeJet Pro 8600 won't connect to my wireless router

This is bizarre. I have had my HP OfficeJet Pro 8600 for about 6 months. It has generally worked fine, and we have used it wirelessly only. But now it refuses to connect to the router. It can FIND the router, and it can find other networks in the area, but it won't connect to the router. I ran the Wireless Network Test, and the results say:
Wireless On - Pass // Wireless Working - Pass //
Network Name (SSID) found - Pass // Wireless Networks Detected - 9
Printer Settings Consistent with Wireless Router Settings - Pass / No Filtering - FAIL //
So it recommends solution as follows: "1 If MAC Address filtering is enabled, and you would like to keep it enabled, you must add the Mac address of your printer to the list of permitted devices for your router before continuing."
Except, guess what, I don't have MAC Address filtering enabled. I wouldn't know how to do that, much less check for it.
Also, before today, this was never a problem. HELP!
Thanks....
If you are interested, here's more detail and background.
Before today, the only problem we have had is that frequently our Apple laptop (OS X 10.6) has trouble connecting to the printer. This has been odd because the printer is connected to the network, and so is the laptop, but the laptop can't find the printer - it thinks the printer is "offline" (even though it's not). Usually, if I wait a while, it will find the printer, and it will resolve itself work fine. If not, we sometimes have found that it can fix itself if you restart the laptop -- restarting the printer does not make a difference. In fact, I did exactly that today, and it resolved itself. And I printed. Fine, right?
But then I wanted to do more printing, and the problem of the laptop not finding the printer came up again, so I decided to really "get to the bottom of this." I don't remember exactly what I did, but somehow I was persuaded by the online help, that the correct solution would be to go into my System Preferences / Print and Fax, and click on the "-", which de-installs the printer, with the idea of re-installing the printer. But then when I tried to re-install the printer, it could not find the printer. Ugh! Wierdly, it found an 8600 Scanner, but not an 8600 printers. After installing and de-installing the 8600 scanner a few times, I eventually deinstalled everything, and I decided to start from scratch. I got my HP disk, and installed all the software again from the beginning (even though it was already there), and then it looked for my printer, but couldn't find it. So then I got a USB cord, and plugged that in.
So, now I have a situation where I do have a working printer via the USB cord, but no wireless connection at all. In particular, since the Office Jet Pro 8600 won't connect to the router, I don't know what else to do. My Apple MacBook pro is 2 feet away from the printer, and it is connected to the router just fine (as is my blackberry), and I have never before had a problem connecting to the wireless router by the printer.
Any suggestions?

There are two things that can trip the mac filtering test to fail: actual MAC address filtering setup (sounds like this is not the case) and using wireless channel 6 or automatic for wireless channel in the wireless network settings (in the router). Since it does show failed for MAC filtering and you do not use this option, try changing the wireless channel in the router to 1 or 11. Those two channels provide the best compatibility with printers due to less interference. Almost everything defaults to auto or 6 for the channel and this causes a lot of interference. This change should not affect anything at all. To do this, you may need to contact the router manufacturer as the process differs from router to router.
What brand and model is the router?
Has anything in the network settings changed at all?
What version is the Mac OS X? There may be additional steps to take as it sounds like there are two separate issues involved and this could be revisited later.

HP Officejet Pro 6830 Won't Connect to WiFi

I've had the HP Officejet Pro 6830 for 6-9 months, it's been working great wirelessly the whole time. Three nights ago we had a power failure, now the printer won't connect to the wireless router. It sees the SSID, but when I enter the password, it says that the password is wrong. I am using an ARRIS Cable Modem. Any suggestions?

Hi @CWoodland ,
I see that you are having issues with setting up the network again for the printer, you are getting a message that the password is wrong. I would really like to be able to help you resolve this issue.
I would check the network password on the Mac, to verify the correct password is being entered.
How to Find the WEP or WPA Key or Password for Your Wireless Network.
You might have to restore the printer defaults and try again.
Go to Setup, Network Setup, Restore Network Settings.
Then run Wireless Setup Wizard again from the printer's display.
Go to Setup, Network Setup, Wireless Settings, Wireless Setup Wizard.
If you need further assistance, just let me know.
Have a great day!

Officejet Pro 8600 won't connect to wireless with Wireless extender connected

I am trying to get an Officejet Pro 8600 to connect to a wireless network, but it will not connect when my wireless network extender is connected. Once I disconnect the extender, it connects fine. Here is the setup. I have a Netgear wireless cable gateway CG3000D with a Amped Wireless Dual Band Router (R20000G) connected to the Netgear via ethernet cable. The Amped router is setup as a wireless extender, the Netgear and Amped share the same SSID. All my other devices work just fine connecting, laptops, cell phones, and IPads. When the Officejet 8600 tries to connect with the Amped connected, it tells me invalid password. Once I disconnect the Amped, the Officejet connects just fine. Any ideas how to get the Officejet to connect to the wireless with the Amped extender connected? Thanks

Are you using the same passkey on the extended network? (It is best to)
If so I would try using different SSIDs. The printer will try to connect to the network with the better signal which might change depending on wireless interference. There is no way to force the printer to connect to one network over another if the SSIDs are the same.
One other possibility. Is the passkey the same for both 2.4 and 5ghz on the Amped Dual Band router? Most routers can be set up to have different passkeys for each band. The printer is a 2.5ghz device and will need that password the same on both the Amped and Netgear routers.
Please let me know your results. Extending networks is becomming more common. Understanding how to work with them will help everyone.

Officejet Pro 7780 Won't Print Black

Only 1 year old. Colors are okay, but I either get a horrible quality black or none at all. Text and graphics affected. It's not the ink cartridge, as I have replaced this. Have also powered down/up, cleaned print jets, re-alinged, recalibrated linefeed, re-installed/updated driver and reflashed/updated firmware. All to no avail. Occasionally get a message that alignment is bad, and the alignmnet routine also gives me an error. In rare occasions (usually while prinitng from internet source), or faxes that arrive, the black is okay. But these are exceptions.
Thanks.

Did you get any response to you query. My officejet pro, also just over a year, will not print the black ink. I have tried cleaning the print head - it juts gets worse, I have tried changing the print heads - but no difference. I have changed all the cartridges and then it goes mad and says they all need replacing. Now after switching off for a while it prints some black but has lines going through it. Surely the shelf life of these printers must be longer than a year! Any ideas?

HP Officejet Pro 8600 - Trying to connect to wrong wireless network.

I have cable wireless and due to provider requirements I have had to disable my hub wireless and plus in another router to the hub to provide wireless. The hub has a network name and the router has the same name but shows a "2" after it. When I try and connect my printer to this itonly picks up the Hub and says wireless is disabled which is correct. How can I get it to recognise the router instead?
I hope this makes sense

Officejet 6500A plus won't connect to new wireless router

I recently purchased the Netgear R6250 Wireless Router. My HP Officejet 6500A plus was able to connect to my old router, the Netgear WNDR3400, but it will not connect to my new router using the WPS feature, nor the Pin method.
I get "An error has occured" message when using the WPS, and an "Invalid Passphrase" with the manual input. I have verified the passphrase several times with the same result.
Is the issue with my new router (i.e. I need to make some sort of change to its settings that are not indicated in the manual) or is there an issue with the Printer (i.e. something special needs to be done to allow it to connect to this new router)

Yes, download the user guide here.

My new HP Office Jet pro 8600 won't connect to my wireless Airport

I try and set up my new Office jet to my wireless and I get the message: More than one access point/wireless router has been found that matches your wireless network name. I only have one router and it is an Apple Airport Extreme. I've tried doing throught he network wizard and tried doing it through the installation on the computer with it directly connected to the computer. I called HP and was on the phone for an hour and all they could come up with was that the Airport had 5 GHz and so it will sense two routers. Huh???? What can I do? I don't want a new router since I just got that one.

If your router supports dual band broadcasting 5Ghz and 2.4 Ghz, log into your router and look at the two wireless profile names. The names (SSID) should be changed so that they are different from each other for each band 5 and 2.4. Also if the SSID is the default SSID that ships with the router, change it to a unique name as a neighbor within range may have the same SSID. Rename to "my unique SSID" and connect the printer to the new network name "my unique SSID" as example. If you need further assistance, list the exact model of your router

HP Officejet pro 8500 won't print and keeps asking for a proxy setting. Help.

HP Officejet pro 8500 won't print and keeps asking for a proxy setting. Help.

Hi,
Can you confirm that you have an Officejet 8500a or Officejet 8500? On the 8500a model, you can set the networks proxy address and port setting from the front panel of the printer (setup>Webservices setup>proxy). If you are unsure what your proxy settings are you'll need to contact your network admin. If your network uses a proxy users name and password for all devices, you need to enter this information along with the proxy address and port in the printers embedded web server. Type the products IP address into an internet brownser window (printer must be connected to the same network as PC). Select the network tab, and than look for the proxy settings option. Enter in the information and click apply. Once the networks proxy information has been correctly inputed into the embedded web server, try printing again. If unsuccessfully, you might try reinstalling the printer software after uninstalling it. Hope this helps!

HP Officejet Pro 8600 won't save scanned document in searchable PDF or .rtf format

HP Officejet Pro 8600 won't save scanned document in searchable PDF or .rtf format
The scanner scans the document without a problem but when I select 'SAVE' and
specify a location and file name, a system error 'The HP scan application was
unable to save the file to the specified location'. It will save a regular PDF file
or a JPG file with no problem, but trying to save an searchable PDF or .rtf file
results in the above mentioned system error.
This problem occurs either from HP SCAN or from the 8600 scan panel.
The computer is running Windows XP and the I.R.I.S. OCR software is
loaded.

Hello TrailsEnd,
Welcome to the HP Forums!
I understand you're receiving an error message "The HP scan application was unable to save the file to the specified location". I will do my best to assist you!

Officejet Pro 7780 - Unable to print or scan

I have HP Officejet Pro 7780 printer that can be connect to Netgear router by cable or wireless and by wireles to HP Pavillion laptop running Windows 7. I use to be able to print and scan using HP Solution Centre or use MS Windows drivers,however after a Windows update (not reverseable) I can neither print / scan using either drivers.
1) I can install / replace MS Windows drivers (eg. using tab "Devices and Printers" - "Add a printer" from desktop start button. Add a printer finds the printer, and IP address and installs the driver). However it then reports the printer as being offline (although it is turned on and prints from other devices).
2) *Similarly installing the latest HP driver package (OJProL7X00_Full_14) the software finds the printer and IP address and then installs the software but then cannot configure and comes up with a fatal error and uninstalls. It then proceeds to look for solution having run log, and says solution found. Proceeding through the process though did not work, as the next time around on restarting and reinstalling the printer is not even found.
Neither has it helped to do a maximum level clean using OJProLX00_Scrubber_14 and HP Print and Scan Doctor and use a 3rd party registry cleaner, though this gets one back to point "*" above.
I have wasted many days trying to sort this,
Suggestion?

Same annoying problem for me. They have a real issue and it is not getting taken care of.

Officejet Pro 251dw won't print with applications inside Parallels 9

I've used HP printers with my Mac computers for years and had no problems, even when I was working with Windows XP and Windows-based applications inside Parallels Desktop on the Mac. All I would have to do to have the Windows-based software capture the printer (connected with a USB cord) was to click on a drop-down menu item under "USB." Recently I upgraded our OS to Mavericks and had to upgrade Parallels from Version 6 to Version 9. A week ago we had to replace our old HP Deskjet 6500 printer, and we chose the Officejet Pro 251dw. We connected the new printer wirelessly to our home network, and we were able to print from both our desktop iMac and our MacBook Pro with no difficulties. But when I needed to print something from PrintMaster 12, a Windows-based desktop publishing program running on Windows XP inside Parallels Desktop 9, the job wouldn't print, and I got a message that the printer wasn't connected. After doing my own troubleshooting, I spent several hours on the phone with Parallels tech support, including having them connect to my computer over LogMeIn and change all sorts of settings, but the best I could get was that the printer queue report said that the job was printing, but the touch screen on the printer flashed rapidly back and forth from "printing" to the date and time, with a large red X next to the date-time read-out, and still no job printed. After having two or three first-level techs and then a second-level engineer working on the setup, the Parallels people finally gave up and said that the problem must be in the settings inside the printer and that we'd have to have someone who works with printers.adjust them. Has anyone out there had this sort of problem working with Parallels Desktop 9 and the Mavericks OS? It wasn't just the desktop publishing software; the same thing happened when the engineer went into the Windows XP printer settings and tried to print a test page.

Rocky8,
This is a little outside our area of printing, but I'll try and help you the best I can. My question for you is the printer showing up under the USB menu in Parallels. If it's not showing up then you need to determine why the USB connection isn't showing up in your Parallels USB menu. This could be a couple of issues, but the one that I think might be happening is the version of the USB port your using. Can you verify that you're not connecting the printer via a USB 3.0 port. Try plugging into one of your other USB ports to see if the printer will show up in the parallels USB menu.

HP Officejet Pro 8500 won't install

My HP Officejet Pro 8500 won't install on my second Macbook Air (while it did on my first; both new Macbooks with up to date software).
The message I get is: "Softwareaktualisierung kann aufgrund eines Netzwerkproblems nicht nach Updates suchen." (Update software is unable to search for updates due to network problems). But the network just works fine, as does the software update when approached by the apple menu. Everything can be accessed without any problem - except this driver.
It also does not help to download the OS X drivers from HP - this also won't install the printer, probably for the same reason.

For some unknown reasons, it now worked via the general software update (after I got 50 error messages before).
