XEROX 7835 problem machine

So if this is what it takes....<br> <br> So we signed a service level agreement on a 7835 with Oxbow. The machine is now only 18 months old. In the last 6 months I most probably had 20 plus visits from various technicians. This for a machine that according to the specs, is only running at 17% of its capacity.<br> <br> Excuses from rollers that is dusty (sometimes in 5 days), bad paper quality (I only use rotatrim), the machine is to close to the window, etc. Never the machine.<br> Our certificates are printed on 300g, which must be reduced to 280g. Yet the specs indicates that it can print up to 300g. <br> The wireless unit was replaced with a cable as the \signal bounces from the walls"(router is about 14 m away). It also took a Hello Peter report before this was done"
