HP Envy Pro 6400 printer drops off network

[timothyhuber]

The HP 6400 regularly drops off my WiFi network and I have to pull the plug and restart the printer to connect. I have experienced this ever since I purchased. Initially, it was a Google Nest Wifi mesh network but I recently upgraded the network to a Netgear Orbi Wifi6 mesh.  The behavior has continued. 

I see there are some other instances of this flagged in the community, but there does not appear to be any sort of resolution.  There were some comments about issues with 2.4Ghz/5Ghz networks but given that every other piece of Wifi equipment I have seems to have no problem navigating that scenario, I doubt that's a real issue.

Would appreciate any suggestions?

Welcome to the HP support community.

I understand that you are getting printer connectivity issues

Are you getting any error messages?

Which operating system is installed on the computer to which this printer is connected?

Meanwhile:-

Perform a power reset

1. Turn on the printer, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Wait at least 30 seconds.
5. Plug back the power cable straight to a wall outlet and printer without any surge protector.
6. Turn on the printer.

Update the printer firmware

Let me know how it goes.

Thank you for your reply.

The only error messages I receive is when I attempt to print or scan from either my Windows 10 computer or my Android phone. and the printer appears offline.  I have confirmed this by using the HP Smart app on both Windows 10 and on Android.  The printer itself appears normal, there are no lights flashing or other error messages.

My only recourse at that point is to perform a power reset, as you described.  While I appreciate the suggestion to power reset, that is a workaround not a resolution. The issue is that the printer drops off the network regularly and has to be power reset.

From browsing the support community, it appears that I am not the only one with this issue.

I understand that you are getting the printer offline error, follow these steps to fix the issue.

Use HP Print and Scan Doctor to fix connectivity and printing issues.

Download HP Print and Scan Doctor.

1. Run HPPSdr.exe from the download location on your computer.

2. Once HP Print and Scan Doctor opens, click Start, and then select your printer.

   • If your printer is not in the list, turn it off and on, and then click Retry.

   • If there is a connection problem, follow the instructions in HP Print and Scan Doctor.

3. If a screen prompts you to turn on printer updates, click Yes.

4. If a screen prompts you to make your printer the default printer, click Yes.

5. Try to print.

Assign a manual IP address and that should fix the issue.

Find the printer IP address to assign it manually.

1. Make sure there is plain white paper in the input tray.

2. Touch and hold the Information button  for 3 seconds.

   All the control panel buttons light up.

3. At the same time, touch the Information and Resume buttons .

Setting a Static IP Address

Once you know your printer’s IP address from the page you printed, entering it is pretty easy. Here’s what you do:

1. Run your Web browser.
2. In the Web browser’s address bar, type the IP address of your printer and press Enter. Assuming you entered the right address, the HP printer control panel should appear.
3. Click the Networking tab.
4. Under Connections, click Wireless.
5. Under IP Address Configuration, click Manual IP.
6. Enter the IP address, subnet mask, and default gateway in the appropriate boxes.
7. Click Apply.
