Abstract
A system of measuring the bare belt signature of a surface that does not require the use of extra print jobs, or extra belt cycles, during the printing of the actual print job. Instead, the inter-document zone and other 'toner-free' areas within the test job itself are used to extract an estimate of the bare belt signature. More specifically, prior knowledge of the job content and of the location of the area between image pitches is used to identify areas of the belt that should be toner-free. These areas are then treated as 'bare belt' segments, and the sensor signal for these areas are extracted, aligned according to their spatial location along the belt, and then averaged to produce a final estimate of the bare belt signature.
