Abstract

A method for determining a working gap includes a first recording step for ejecting ink from a recording head onto a first recording medium having a known medium thickness to record a test pattern, a first imaging step for capturing the test pattern recorded on the first recording medium in each of a state where a distance between the recording head and the first recording medium is a first distance, and a state where a distance between the recording head and the first recording medium is a second distance, a function calculating step for calculating a function to determine the distance based on the number of pixels of the captured test pattern, a second recording step for recording the test pattern on a second recording medium, a second imaging step for capturing the test pattern recorded on the second recording medium, and a working gap determining step for determining, based on the number of pixels of the captured test pattern and the function, a distance between the recording head and the second recording medium.
