Feed Motor Cal
The “Feed Motor Cal” test calibrates the speed of the Supply Drive Servo Motor to
the speed of the Take-up Nip Drive Servo Motor. The media and supply cassettes
must be removed prior to performing this test. The two values will be stored in the
DEC. DSP/Plate menu in DSP address location 4 and 5.
This test should be performed after replacing either servo motor or supply/take-up
SDM boards
