Our Xerox Copier has been down for some time now with no hope. We called in two companies who tried to repair without any luck. All they gave us was recommendation to replace Fuser, Belt etc. We called Kensington Office Machines as our last option. The tech from Kensington was very polite, friendly and knowledgeable. Apparently, the sensor flag somewhere was misaligned. He fixed our Workcentre 7970 in no time. Thank You Guys.
