968W AIO Dell: When trying to scan or make copies, the printer shuts down and turns back on. It will pass thru a blank paper when trying to make copies or scan after it re-initializes. After several tries, it will then make the scan or print. Frustrating! It behaves normally when controlled by PC; just does this when I use buttons on the actual printer itself.  Just started doing this in the last month.  Have had printer for three years+.
