MICR reader mechanism (only when the printer is used with the MICR reader): 240,000 passes The MICR reader is defined to have reached the end of its life when it reaches the beginning of the Wearout Period. MTBF: 180,000 hours Failure is defined as Random Failure occurring at the time of the Random Failure Period. MCBF: 29,000,000 lines This is an average failure interval based on failures relating to wearout and random failures up to the life of 12 million lines. Receipt: Life: Mechanism: 15,000,000 lines Thermal head: 100 million pulses, 100 km Auto cutter: 1,500,000 cuts MTBF: 180,000 hours MCBF: 37,000,000 lines Reference Information 4-11
