The scanner will loose it's ability to reset a starting point when the power is turn on or off, resulting in Scanner error or locked. Printing is also disabled. This is routine problem. There is a major problem in tonner sensing hardware and software. When new tonner installed, machine will not reset and believe that tonner is still empty. This is confirm error. This is common problem in this samsung model printer. The exit for printed paper is poorly planned. I like the size of this if improve somthing it is better perform in all manner.
I suggest to people who plan for purchage it think a lot and focus on other model. This is my own view.
