2.4.3.2 Calibrated Test Product Page
1. For calibrated test product purging, select Open Cover Commands. Open the front printhead
cover.
2. 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.
3. 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 de-
livery mechanism. Provided the assembly has been set up correctly this should be almost
negligible.
