Hey @regloor,

Welcome to the HP Support Forums!

I understand that you are having some issues with your Laserjet M176n asking to cool down after printing. I can help you with that.

To start, make sure the printer is plugged directly into a wall outlet and not a surge protector. Once done, while the printer is powered on, remove the power cable from the back of the printer for one minute.

Please let me know if you still see the cooldown issue after following the above. If you do not, please click on Accept Solution. If you appreciate my help, please click on the thumbs up icon. Both icons are below this post.

"remove the power cable from the back of the printer for one minute"  helped perhaps ( not sure ) for the cool-down but print of 1 page always take 1,5 minutes. 

This is a lot too much. 

Do you have a solution for that ? 

If not, I will have to bring it back to the shop and ask refund.

Alright, as a test, take a sheet of paper and make ten copies and let me know if you see the cool down message or if the copies are made any faster.

no cool-down message and it took about 3 minutes for 10 color copies, ie about 20 seconds / copy.

So the question is : why 1,5 minutes by print when printing envelopes.
How can we make it faster for envelopes ?

Thank you very much for your help.

Since you could quickly make copies it's not necessarily the envelopes, it's either an issue with your PC or it's an issue with your network.

If the printer is connected to your router through an Ethernet cable:

1. Turn the printer off.
2. While the printer is powered off remove the power cable from the back of the router for one minute.
3. When the lights return on the router, turn the printer on.

Now:

1. Try printing on regular paper (as opposed to an envelope).
2. Try printing an envelope.

Please let me know if this improves your print speed. If the regular page prints quickly, but the envelope does not, it's an issue with either envelopes or the program you are printing from. If neither print quickly, the issue is related to your operating system or print system.

it is a lot better now : I come to about 25 seconds / envelope !! ( print quality photo ) in place of 1,5 minute

Thank you very much for your very useful help.
