I have this copier at my workplace. It sits outside my office and I use it hourly while on the job so this gets used up to 10 hours a day. By reason of default that it is closest to my office I get asked to help the 'male' personnel when they get stuck programming it or jam it up!!! I would estimate that we've had this machine for well over 5 years and it has been very reliable. It is a basic monochrome (black ink) copier and when it gets going it can print up to 32 pages per minute. I like the fact that the base has 3 paper trays/drawers so we keep two stacks of 8-1/2 x 11 paper in the top, 8-1/2 x 14 paper in the middle and in the bottom drawer we keep the 11 x 17 paper. If a big job comes along I can change any of the trays to whatever is needed the most. I can collate, do two sided copies, enlarge and reduce to whatever size is needed and constantly use the automatic paper feeder to do my copying while I am busy doing something else. It has a power down mode after a certain time period so it is energy saving which is probably very wise for our office as it is left on 24/7. Maintenance has been very minimal considering how much it is used and getting parts has never been a problem. Highly recommended!!!
