HP OfficeJet Pro 8720 - Will not Wake up

[Daniel_S1]

I connect my HP OfficeJet Pro 8720 to my iMac (OS 10.11.6) directly using a USB port. When the printer goes into sleep mode, I am unable to wake it up. The only solution is to turn the printer off and on. I have upgraded all the drivers, it doesn't seem to make a different. I cannot find a way to turn the Sleep Mode OFF. There are only options for 5/10/15 minutes.

Thanks for your help!

@Daniel_S1, Welcome to HP Support Community!

Ensure that the printer is up to date with its firmware and Mac is up to date with its software. If you are unsure you may use the links below to update the printer firmware and Mac software:

Update printer firmware

Update software on Mac 

Remove and add the printer

Click the Apple menu, and then select System Preferences.

Depending on your operating system version, click Print & Fax, Print & Scan, or Printers & Scanners.

Click the name of your printer, click the Minus sign, and then delete the printer.

Click the Plus sign, and then click Add Printer or Scanner.

Click the Use or Print Using box, and then select AirPrint

Click Add to add the printer to the list.

Try to print.

Also, check if your router has any firmware updates. Try assign manual IP to the printer. The steps on how to set a manual IP address can be found here.

For the DNS servers please use 8.8.8.8 for the Manual Preferred DNS Server and 8.8.4.4 for the Alternate DNS server. These are Google’s public DNS servers.
