5. Pull the camera carriage to the front of the printer.
6. Slacken off the auger clamp screw.
7. Release the auger, nozzle and syringe as one assembly from the drive gear
and the ‘C’ clamp.
8. Remove the pneumatic air connector from the rear of the syringe assembly.
9. Dispose of the syringe and nozzle components in accordance with any
national, federal or local disposal regulations.
10. Fit a replacement nozzle to the auger.
11. Fit the pneumatic air connector to the rear of the syringe assembly.
12. Lift the complete assembly up toward the auger drive gear. The auger valve
screw engages with the square shaft of the drive motor, rotate the exposed
portion of the drive belt at the same time pushing the assembly upward
ensuring that it is in the fully up position.
13. Refit the assembly into the ‘C’ clamp.
14. Refit the in-line air connection to the pneumatic air connector.
15. Tighten the plastic auger clamp screw. Do not over tighten.
16. Remove the nozzle dust cap. Ensure that the nozzle assembly is in line with
auger valve and not bent or at an angle.
17. Close the printhead front cover.
18. Reconnect the printer to the pneumatic supply and unlock the mains elec-
trical isolator.
19. Switch the mains isolator ON.

21. Select Load Board and load the calibrated test product as described in the
Calibration section of this manual.
22. Select Product Changeover.
23. Select UnLoad Screen.
24. Select Stinger Dispenser. An extended menu is shown.
25. Select Purge Process. The camera axis drives to the centre of the board.
There are two process types for purging - Standard Purge Process and
Enhanced Purge Process. The former purges air pockets from the dispense
head, alternatively, purging is used to empty a dispense head of material. The
enhanced process allows the purge to be carried out at a purge station. The
purge station also has a nozzle wipe facility.
The enhanced purge process is used when a complete system purge is
required, either at the start or at the end of a production batch. As this process
requires a large volume of material to be purged, a purge station is used to
collect it.
Purge station consumable monitoring is turned on in Maintenance\Machine
Setup\Options\Stinger Options\Stinger Consumable Monitoring.
When the pot is full an action panel is displayed reminding the user to replenish
the pot.
26. For calibrated test product purging, select Open Cover Commands. Open
the front printhead cover.
27. Selecting Start Purge starts the purge routine. Adhesive is delivered onto
the centre of the boards’ upper surface until the Stop Purge button is
selected.
28. Purging should be monitored to ensure that the adhesive delivery is flowing
without being spurious or spluttering. Any signs of inconsistency are likely
to be due to air pockets in the delivery mechanism. Provided the assembly
has been set up correctly this should be almost negligible.
29. Load the screen.
30. Close the printhead front cover.
31. Press the System button.
