While the copy quality is excellent, the controls and setting functions are way too complicated and confusing. Just to change paper size settings requires wading through several hard-to-understand menus. Our previous copier automatically sensed paper size and adjusted settings accordingly. Also, while the documentation says we can use smaller size paper in the bottom paper drawer, the control settings will not recognize anything but 8.5 x 11. The extremely slow warm up when the unit is initially turned on is also annoying. It takes two or three times as long to get to the place where we can actually make copies as it did with our previous copier. It also goes into "sleep mode" way too soon, further slowing up intermittent copy operations. Finally, printing a "test" page every time we turn it on is a waste of paper and time.
