7520 wont wake from sleep

[Terry104]

My printer will not wake from standby mode, the touch screen will make clicks when touched but never turn on, this is a wireless connection and nothing about how it is connected has changed, if I unplug the printer and plug it in it works fine until it goes to sleep....

Thank you for the reply, but the issue is with the printer, not the computer software....when the printer goes into standby/sleep mode, it will not wake up, touching the printers touch screen gets no response, pushing the printers power button will get the click sound but will not shut off the printer or cause it to wake up, I have to unplug it and plug it back in, after it starts up it works perfectly and absolutely nothing has changed on my computer.

I have tried the firmware update hoping to resolve this issue but it says that it is up to date.

I love this printer and it works perfectly until it falls asleep...

Use HP Print and Scan Doctor to check connectivity

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 in 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 manual IP address and that should fix the issue.

Check the network configuration or print the wireless test report

1. From the Home screen, touch the Wireless icon, and then touch Setup.

2. Touch and drag your finger vertically to scroll through the options. Touch Display Network Summary or Print Network Configuration Page.

Setting a Static IP Address

Once you know your printer’s IP address, 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.
