Xerox Phaser 8400 Service Manual

4-44 Phaser 8400/8500/8550 Color Printer
Y-axis Drive
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.
