Hello,
I just bought a Officejet 4620 multi function device and apart a lot of issues with ePrint not working at all, which I really don't care about, I am facing a strange problem. When I first connected the power cord the printer turned on regularly and performed a series of self tests which worked fine. I was able to print from an iPhone and a Windows laptop without issues and after some trouble I got the scanner to work too, everything through WiFi, without ever connecting any device to either USB or LAN ports.
The problem arises when I turn the printer off: for some time I can turn it on again by pressing the power button on the device keyboard, but if I leave it off for a long time (let's say a couple of hours) it cannot be turned on again unless I unplug the power cord and then plug it in again. I have noticed that there is a green led behind the device; if that light is on it means I can turn the device on without issues, but when it goes off I must unplug and plug back in the power cord for the device to turn on.
Is there anything I can do to fix this?
Thanks
Andrea
