Recently purchased a 6500DN and have noticed that when I'm printing a two-sided document multiple times, the printer doesn't seem to keep up. I print a simple two-sided letter and after the first print, the printer takes over 10 seconds to print the next, and then again and again. There is a long enough gap between prints that the print motor is able to turn off!
It seems as if the printer is receiving the document everytime it prints, instead of receiving it once and just printing off copies!
Anyone able to help me here? I'd love to have this printer get even close to the PPM promised by this printer!!!!
