Hi,
Take a look at this link.
I hope that this helps.
Dear Support!
Everytime my printer goes for standby for some days, after that I'm not able to print. The Easy Printer Manager says network cable disconnected, but if I print a status page it can be seen the printer is connected to wifi with valid IP address. If I try to print something it says the printer is offline, can you help to resolve the issue?
Thanks,
Peter
