HP ENVY 7640 - When Prining Wireless - " Printer is Offline" or "Printer is not Available"

[CVS2]

I have 3 computers that print using the HP EVNY 7640 for the past 2 years with no problems until the last 2 weeks. All computers are on Windows 10. Two of the three computers print through my wireless network. The other computer prints via USB. The 2 printers that print through the wireless network have not been able to print for the past 2 weeks and when I attempt to print I get messages that indicate "Printer is Off Line" or "Printer is not available". I have uninsalled and reinstalled the printer software on all 3 computers and still have the problem. I have checked my Linksys router and it shows the printer as "On Line" . I have made no changes to any software or routers other than normal Windows 10 updates. The wireless network itself seems to be working just fine. I have no problems printing with USB connection. I have check the wireless settings on the printer itself and they look OK to me.

Suggestions on how to fix are appreciated & thank you

@CVS2,

Thanks for reaching out to the HP Support community!

• The Wifi network that you have is that a 2.4GHz network or a 5GHz network?
• The Wireless light on the printer, is that blinking or solid?
• Do you have any security software or antivirus installed on the 2 PCs?

Let's try these steps:

Step 1: Restart the WiFi Router, Printer, and PC

• Turn off the Wifi Router, wait for 60 seconds, turn it back on.
• Turn off the Printer, wait for 60 seconds, turn it back on.
• Restart the PC
• Try to print
• If the issue persists, proceed to the next step

Step 2:  Run the Print and Scan Doctor

• Download and run HP Print and Scan Doctor to automatically diagnose and resolve printer hardware and connection issues.
• After the Print and Scan Doctor opens, click Fix Printing to test your printer, and then follow any instructions to resolve the issue.
• Try to print after running the Print and Scan Doctor. If the error persists, continue to the next step.

Step 3: Check the connectivity

• Make sure the Printer and PC are connected on the same WiFi network.
• Obtain the IP address of the printer by touching the icon on the printer control panel.
• Open a web browser(like Google Chrome, Firefox, Microsoft Edge, etc.)
• On the address bar, type the IP address of the printer and hit Enter.

           

• Check if it opens the EWS page of the printer. (Refer to the below example)

            

• Go to the Tools menu on the EWS page and try to print a self-test page.
• Check if it prints

Let me know what happens.

Just an FYI - The wireless network is 2.5Ghz - The wireless light is solid on the printer. I have Comodo anti virus which I disabbled to see if I could print but no luck. I have done step 1 - did not solve the problem. I have done step 2 (Scan Doctor). The good news is that the scan doctor recognized the printer. It fixed some "port issues". Then I ran a test page. It would not print. I clicked on the "did not print" button and the scan doctor app froze up and I had to restart the computer. I ran scan doctor again, same problem, the app froze up when I click on the "did not print" button after running the test page.

I have not done step 3 yet. Will do so shortly.

PS - I have no other computer related issues. All computers work well & my Linksys router / network works well for everything else

Thanks for your interest

Just completed step 3 - Was able to open the EWS web page and printer is connected to the network. When I clicked the print button, nothing printed & no error message

@CVS2,

Let's try Printing the Network Configuration Page.

From the main menu on the printer control panel, slide the screen from right to left to access the set-up menu.

Go to 'Network Set Up'>'Print Reports' > 'Network Configuration Page'

Please share the Report.

Also, there would be a setting called 'Channel' on the router.

Printers have less wireless interferences on channels 1,6 or 11.

If the channel is set to a different number, try changing it to 1,6 or 11 for better connectivity with the printer.

Try to print again.

Let me know what happens.

Cheers!

I was able to print the HP Network Configuration page. What info do you need from it?

Still trying to figure out what channel the router is on.

[CVS2]

Router channel is set to "Auto" for the 2.4Ghz network. I went to change it to channel 1 but I got a message saying all of my devices will be disconnected if I do so, so I stopped for the time being, because I am not sure how to reconnect all devices (I have about 12 devices on my network)

[CVS2]

I have scanned the HP Network Configuation document but I have not figured out how to attach it to a post in this community (or if it is allowed)

@CVS2,

You can change the Router channel to 1,6, or 11. It would not affect the devices already connected.

Please try switching the 3 channels if they do not work.

In case if you face any network issues, you can switch back to the old settings.

Cheers!
