This paper will present the opportunities that exist to improve “Reliability” in the Production printing environment using a strategy that includes Operator Replaceable Components (ORCs).There are varied definitions of “Reliability”. Availability is a commonly used operational measure of reliability performance of repairable systems.1 In a Production environment where a higher volume of output sheets results in greater revenue and profit for the print producer, the preferred definition of reliability is uptime or availability. Alternatively, a definition of the inherent reliability of a system is based on sheets, time or image count between failures or service calls.As we know, state-of-the-art technology selection, robust product design, and six-sigma quality components cannot totally prevent the physics and the mechanics of failure modes from having their effect on a tuned system.Many attributes need to be considered in the identification, selection, and optimization of ORCs for an effective “Reliability” strategy. Examples of attributes that will be explored in this work include functional dependencies, component life, distribution of component life, ease of use and handling, fault isolation and diagnostics, unit manufacturing cost, trigger event, time to maintain or repair, tools, operator skills, and calibrations.
