Hey there! @RonieDeguit, Welcome to HP forums.
I understand you are getting cool down mode error on your printer.
Don't worry I'll try to help you out.
Did you make any changes to your printer?
Does the issue when you make a copy from your printer?
I appreciate your efforts for trying out the steps before reaching out to us.
However, Try the steps recommended below.
Reset the printer
Turn the printer on, if it is not already on.
Wait until the printer is idle and silent before you continue.
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.
NOTE:
HP recommends connecting the printer power cord directly to the wall outlet.
Reconnect the power cord to the rear of the printer.
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.
If the issue still persists try performing an NVRAM reset on your printer and check if it helps.
Since the steps to perform NVRAM reset is confidential. I will send you the steps in a private message.
Please watch your inbox for more information.
If the issue still persists after trying out the steps, it is a hardware issue with your printer.
If the solution provided worked for you, please mark an accepted solution for this post.
Let me know how it goes!
Have a great day ahead! 🙂
