Connection Issues with HP OfficeJet 8620

[Rick037]

Is anyone else having difficulty "wakening" their HP 8620 printers? More often than not I have to shut the printer down and then reboot in order for it to accept a print request.

@Rick037, Welcome to the HP Support Community!

This issue may occur if there are connectivity issues between the printer and the MAC. Let us try these steps to resolve this issue: 

Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Wait at least 60 seconds.
3. Reconnect the power cord to the rear of the printer.
4. Turn ON the printer, if it does not automatically turn on.
5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

Update the printer firmware

Also, check for any software updates on MAC

Click here to know how.

• Make sure the printer and the MAC are connected to the same wireless network.
• This printer supports only 2.4GHz network.
• If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both the networks.
• The wireless status menu on your Mac should also give us quite a lot of information that would help us identify the issue. You can press and hold the option key on your keyboard and click the WiFi icon to get detailed information.

On the printer screen, go to Setup > power management > Sleep > Set it to after 15 minutes.

If the issue persists, restart the network devices

1. Turn off the Router, Printer, and the computer/ mobile devices.
2. Wait for 60 seconds.
3. Turn on the Router first and wait for all the lights to stabilize.
4. Turn on the printer and allow it to configure itself.
5. Turn on the computer/ mobile devices.

Let me know how this goes.
