Unit (ORU) level is 15 minutes.
It includes:
- Identifying the faulty ORU
- Changing the ORU
- Cleaning paper paths
- Testing locally

For these printers it is 10.000 HRS @ 25 % D.C. (excluding print head).
Duty cycle rate estimated for this printer is calculated as follows:
Paper Movement & Print Time
Duty Cycle = ---------------------------------------------------- = 25 %
Power-on Time
Reference usage of 25% duty-cycle is assumed on the basis of the following
parameters : 60% column density, 50% line density, 40% character density, 40
hours/week.
