HP Color LaserJet Pro M477fnw is not communicating with computer only a few seconds after starting

[MotyBP]

I've been using HP Color LaserJet Pro M477fnw for quite a while. Lately when I am printing the printer stays at sleep. Even if I manually awake the printer it still doesn't respond. The connection is great. Every time I click print on my cumptuter i restart the printer multiple times untill it finally prints. Any sullution

How are you connecting, USB or Network? Is the firmware on your printer up to date?

I am connecting with wireless. But this doesn't seem to be the problem. Since sometime the printer remains awake throughout the night while the computer is off. and the screen is frozen

Just to confirm, is your firmware up to date. Print a configuration page and confirm what date code is showing. HP has made many improvements to this model and they are only applied if you have the current firmware installed. Date code for current is 20190113. If this is not what shows on your configuration page then you need to update. First step in resolving this problem.

The device is running the latest firmware.

I found that solution a while ago but for me it didn't work.

Any other solutions?

 In the energy settings page you can check to see what events are set to wakeup the unit. It is actually possible to set it so that no events wake the printer which then requires you to restart the printer to get it to work. If you are connecting USB make sure usb events and control panel are set as valid events to wake the printer. If all these settings are correct then my next step would be to NVRAM reset the unit, check YouTube for videos that show how that is done.

I didn't see any option on what should awake the printer.

It used to work for a long time untill the day the warranty ended.
