Troubleshooting 8-7
8.1 Troubleshooting X and Y-axis Motion
If the Dispensing Head is not moving correctly in the X-axis and Y-axis, refer to Table 8-2 for a summary
of the symptoms, probable causes, and fault isolation procedures.
? NOTE Problems resulting from environmental and application abnormalities, spills,
obstructions, and workpiece irregularities that are not system related should be
eliminated prior to advanced troubleshooting.

TIP To quickly identify problems, look for obvious signs such as burnt, discolored, missing,
damaged, or loose parts, obstructions, and foreign objects. Obvious uncharacteristic heat,
noise, odor, vibration, or movement can be used to quickly isolate problems. If a problem
reoccurs frequently, there may be other root causes to the problem.
