Printer falls asleep and won't wake up!

[RDholt]

My Officejet Pro 8620 falls asleep and then I can't print unless I restart my printer because it wakes up and it is offline. Then, it can take awhile for the print jobs in the queue to actually print. I am confused by other solutions I have found because I don't think my router has settings...? It's a  Comcast Business router and it's connected and that's all I know about it. I don't have an ethernet  cable plugged in right now. It is all wireless connected. I tried turning off the IPv6 and it just disconnected the network connection. I didn't restart the router because I was afraid of ruining everything at my company internet wise. I found the following solution  but I can't make sense of it based on the Comcast router that I have. If anyone can explain how to solve this problem please help! : 

I found this article about the problem online that I will copy and paste a part of here, "The HP rep said the problem was probably with my network, specifically with my router. In the last year I had switched Internet Service Providers. My modem, an Actiontec PK5001, came from Century Link, my local phone company, and is a combination modem and router. I had retired the Amped Wireless router I used to use with my previous ISP and put it in a cabinet. However, HP observed, “We did contact a person in R&D at your [Century Link] router manufacturer and they did confirm that there is no option to control multicast on the router, which we know can cause problems since the printer will not recognize the information being sent to it to initiate the job.”

"I had no idea what “multicast” meant, but I was told the remedy was to disable the wireless portion of my Century Link modem, install a separate router, and run the printer cables through that. Fortunately, I still had my Amped Wireless router. I re-installed it, then went into the settings for the Century Link modem and disabled its Wireless Radio (which is a checkbox). Once all my Ethernet cables were connected to the Amped Wireless router, lo and behold, the HP printer started working normally." Again, this is not talking about the router I have and I don't know how disable the wireless portion of my modem.....ect, 

I do not know anything about my router and I don't know how to use this information to help solve my problem but if anyone does please help!!!!

Thanks!

Thank you for joining the HP Community

I suggest you do a Hard Reset on the printer and update the firmware for the printer.

(1) Turn the printer on, 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) Unplug the power cord from the wall outlet.

(5) Wait at least 60 seconds.

(6) Plug the power cord back into the wall outlet.

NOTE: HP recommends connecting the printer power cord directly to the wall outlet.

(7) Reconnect the power cord to the rear of the printer.

(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

Restart the printer.

Assign Manual IP to the printer:

1) Print a Network configuration page from the printer's control panel. 

2) Look for IP address from the Network configuration page. 

3) Open web browser - Chrome or IE or any other browser that you are using. 

4) Type the IP address mentioned on Network configuration page into the browser's address bar or URL bar and press enter button. 

5) Go to the Network tab. 

6) Click on Networking from the left pane. 

7) Then click on Network Address (IP). 

😎 Click on Manual IP Address and go to suggest a Manual IP. 

9) Scroll down the screen and select Manual DNS server. 

10) Enter the Primary and secondary DNS server from the Network Configuration page into the Manual Preferred DNS server field. 

11) Click on Apply. 

Refer to the video link for step by step instructions - https://www.youtube.com/watch?v=SCnYyq80V9g 

Note: The video is for win 8 but steps are similar for other operating systems as well. You need to enter the IP address in the browser's URL or the address bar to access the printer page.

Create TCP/IP Port: 

1. Search Windows for devices, and then select "Devices and Printers" In the list of results.

2. Right-click the name of your printer, and then select Printer Properties.

3. Click the Ports tab, click on "Add port" select "Standard TCP/IP Port" and click "New Port"

4. Click next on the Add Standard TCP/IP printer port wizard, enter the printer IP address and click next and then click on "OK".

5. Now under the "Ports" tab you will find the Newport with the printer IP address, click "Apply" and "OK".

Restart the computer.
