Calibrating Xpress XL

Keeping your machine in a clean, dust free environment will ensure that all the 

mechanical parts run smoothly. There are occasions when you may need to adjust 

some settings. 

One of the programs included with the system is a calibration utility. This utility 

includes a quick initial system test for checking the basic disc-transporting functions. 

Follow the procedure below to run this test.

Calibration Procedures

To work properly the Xpress XL needs to be correctly calibrated. If not calibrated 

propertly you may experience some of the following errors:

•

  If discs are not picked up from the input spindles

•

  If discs are being dropped off the trays or output spindles

•

  If discs are not centered when placed on drive trays

•

  If the arm has trouble picking up discs from the drive trays/ printer tray

•

  If the printer is not able to clamp the disc properly.

Calibration means making adjustments to the disc production system so the opera-

tion runs smoothly.

Prepare for the calibration procedure

Place a few discs on spindles 1 thru 4. Start the calibration utility program by double-

clicking its desktop icon. The calibration utility’s window will open.

Adjust the spindle calibrations

Click the 

Calibrate Position

 button and click on the button for the spindle you wish 

to calibrate (S1 for example). The disc transport arm will move over to the top of the 

spindle, move down close to the top of the spindle and then stop.

If the arm is not centered exactly over the spindle, the calibration of the spindle must be 

corrected. Use the two arrow buttons and to “bump” the position of the arm counter clockwise 

or clockwise respectively. When the arm is centered, click the 

Save

 button to accept the change. 

Recheck the alignment by repeating this step. Click the 

Cancel

 button if no change is necessary.

Repeat this step for spindles 1-5 & Rej1 - Rej2.

Calibrate the arm height

To calibrate the height at which the arm travels above the spindles and below the 

printer(s), click the Calibrate Spindle Height button.  The arm will move over S3, 

move slightly to the left, tap the top of the spindle, move to the top of the elevator, and 

then back down.  The positions are automatically saved.

Adjust the drive calibration

There is no separate calibration for each drive. Only one station on each side (D1 

or D7) must be calibrated. Have at least one disc on spindle 4. Click the 

Calibrate 

Position

 button and the 

D1

 button. The disc transport arm will pick up a disc from 

spindle 4 and move it over to the drive. Once it senses the drive tray, the arm will 

move back and stop above the drive tray.
