Printer is functioning fine, works wirelessly fine - but will not enter sleep mode. Tried to turn printer off but control panel states 'Initialzation in Progress...do not turn printer off.' It has said this for a couple of days now. Can't turn off. Tried unplugging. Goes right back to control panel at set up, eventually switching to ink level panel and stays.
Printer previously functioned completely since installation - a week ago - it did go into sleep mode.
