9. Users can decide the alignment options, with reference to stencil/screen
artwork design; however, DEK suggest following the procedure below:
a. Make an alignment mark, on the shim, measured 45 degrees above
horizontal as shown.
b. Align the wafer notch or pattern to the alignment mark.
10. Close the front cover.
11. Press PLATE Vacuum. The Plate Vacuum button light is ON. The pins
retract. Shim vacuum holds the shim in place.
12. Press START Vacuum. The Start Vacuum button light is ON. The pallet
moves to the selected conveyor output. If the printer is ready to demand a
product, the pallet transfers into the printer.
13. After printing, the pallet transfers back to the NUTEK Linking Conveyor.
14. If the keyswitch is set to Mode 1 or 3 the front cover can be opened. The
printed wafer is removed and a blank wafer is loaded. If the keyswitch is set
to mode 2 the pallet is transferred to the ball placement printer for process-
ing. On completion, the pallet is returned to the conveyor.
15. Remove the wafer and restart the cycle for the next wafer.

All transit brackets and setting rods should be removed prior to powering up
