Looking over these stats everything certainly seems to be in order. This printer is certainly prepared for some very serious use and it obviously going to thrive in a mid-sized office. The issue I am concerned about is when the use slows down a bit or when it is used in a smaller office setting. This is when the 99 second warm up time could be an issue. If the printer is not being used all the time it is going to need to warm up before being used- who wants to wait over a minute and a half if they are only printing something every half hour or so? This is going to be an issue with any big color laser, not just the CLP-510n though, so its not so much a flaw as a characteristic, but that is not going to make you feel better when you are waiting.
