5.12 Feed Motor Calibration Test

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. To perform this procedure you
must unload the media and remove both supply cassettes.
This procedure should be performed whenever a supply or take-up servo motor
or supply/take-up SDM board is replaced. Prior to performing this procedure
you should balance the forward/reverse spindle direction of the supply motor by
performing the Supply Motor Offset Alignment Procedure.
To perform the procedure:
1. Launch Avdiag from your PC.
2. In the Align Menu select "Feed Motor Cal".
3. Follow the instructions in the dialog box.
When the test is completed two values will be stored in the DEC. DSP/
Plate menu in DSP address location 4 and 5.

Prior to adjusting the A/B spindle sensors you must check the supply roller disks
at each end of the rollers. See Figure 5-4. The disks between spindle A and
spindle B and the drive roller must be touching.
