At Westmark, we support about 50 machines under service contracts.
Machines that are left up and running 24 hours per day tend to be
more reliable (i.e. have more hours between failures).  Cooling down
and warming up a machine ages it faster than letting it run.

Preventive maintenance, however, like cleaning air filters and
lubricating moving parts, seems to be required more often if the
machine is kept on.
