MCBF (Mean Cycle Between Failure)*
1 End of life is defined as the point at which the printer reaches the beginning of the wear out period.
2 This is a random failure occurring at the time of the random failure period.
3 This is an average failure interval based on failures related to wear out and random failures up to the life of 10 mil-
lion lines.
