While on sleep mode my 8620 fails to print.  The document stays on queu but will not print until I turn off the printer and then turn it back on.

Hi @Marvin15,

I'd like to help with the sleep mode issue.

Try the suggestions below to resolve the issue-

Reset the printer -

• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
• Reconnect the power cord to the printer.
• Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

Set a Manual IP-

To set a manual IP and try the steps below

--->Touch on the wifi icon ((i)) on the printer, and take down the IP address 
--->Open a web browser (ex Chrome or Mozilla) and type in the printer's IP
--->then go to network ---> general ---> network protocols ---> select IPV4 only-->apply 
--->go to wireless ---> wireless 802.11---> select manual ip ---> apply
--->Enter 8.8.8.8 for the first DNS and 8.8.4.4 for the second DNS.  
--->then go to settings on the main ews page --> power management ---> select sleep mode to max 15min
 

Hope this helps! Keep me posted.
