Method and apparatus for compensation of arbitrary banding sources using inline sensing and control
Abstract:
A method for compensation of banding in a marking platform includes: initiating a signature learning mode; establishing a timing reference after marking modules have achieved constant velocity; marking a test pattern over multiple intervals of a lowest fundamental frequency among marking modules; obtaining image data for the test pattern from a sensor; and processing the image data in relation to the timing reference to form banding profiles for multiple banding sources. Alternatively, the method may include: initiating a cycle up stage in a phase learning mode; establishing a timing reference after marking modules have achieved constant velocity; marking a test pattern over multiple intervals of a lowest fundamental frequency among marking modules; obtaining banding image data for the test pattern from a sensor; and processing the image data with banding signatures in relation to the timing reference to form phase estimates for each banding signature. Additional embodiments are also provided.
