Y-axis Geometry (Continued)
Rotates the drum at a constant velocity and samples the Y-axis position. Uses the data to
determine Y-axis motor and drum vibration and the most significant other vibrational frequencies.

This procedure performs a "4 corner" test using the minimum and maximum velocity and
acceleration used during printing and minimum and maximum load for a total of eight test cycles.
Measures servo response parameters under various conditions.
