M477fdw won't stay in standby - keeps waking up

HP Recommended
Microsoft Windows 10 (64-bit)

Hi,

My M477fdw Laser Jet Pro has started waking itself up a minute or two after going to sleep.  It used to go into standby / sleep mode just fine.

 

It's connected to my wifi and hardwired to a desktop.  I've rebooted the desk top, tried leaving it powered off and disconnecting the printer cable.  none of those actions helped so I don't believe the desktop computer is involved.  Is there a setting buried in the printer that causes this or something buried in a queue?  I've checked all the queus I know of an there's nothing sitting there.  I've changed the "go to sleep in X minutes" setting.  No help.  Rebooting the printer doesn't change anything.

 

Any idea what's making the thing wake up all the time?

hi,

May the printer connected to a phone line? for my experience, such behavior may occur due to a phone line condition.

 

If it is connected to a phone line, please unplug the phone cable and check if that may make any difference then.

 

If it makes a difference, try replacing the phone cable to another 2-wire phone cable, if this is a DSL line also make sure it is properly connected through an ADSL Micro-filter to its Phone port and try replacing the Micro-filter, if these make no difference please clarify what phone line type the printer is connected to, assuming it is.
