	&nbsp;</li>
	<li style="text-align:justify"><span style="font-size:18px">Restart the scanning software</span><br />
	&nbsp;</li>
</ul>

<h3 style="text-align:justify">&nbsp;</h3>

<h3 style="text-align:justify"><strong><span style="font-size:18px">Step 3: Verify Scan Stability</span></strong></h3>

<p style="text-align:justify">&nbsp;</p>

<p style="text-align:justify"><strong><span style="font-size:18px">Run a test scan to confirm:</span></strong></p>

<ul>
	<li style="text-align:justify"><span style="font-size:18px">No frame drops</span><br />
	&nbsp;</li>
	<li style="text-align:justify"><span style="font-size:18px">Real-time rendering without lag</span><br />
	&nbsp;</li>
	<li style="text-align:justify"><span style="font-size:18px">Stable data transfer to the workstation</span><br />
	&nbsp;</li>
</ul>

<p style="text-align:justify"><span style="font-size:18px">If scanning stabilizes immediately, the issue is confirmed as WiFi-related rather than scanner hardware failure.</span></p>

<h2 style="text-align:justify">&nbsp;</h2>

<h2 style="text-align:justify"><span style="font-size:18px"><strong>Temporary Chairside Optimizations:</strong></span></h2>

<p style="text-align:justify">&nbsp;</p>
