  should calibrate it.</p>

      <p>Make sure your scanner is connected to your computer with a cable or
      over the network.</p>
    </item>
    <item>
      <p>Scan your calibration target and save it as an uncompressed TIFF
      file.</p>
    </item>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Settings</gui>.</p>
    </item>
    <item>
      <p>Click on <gui>Settings</gui>.</p>
    </item>
    <item>
      <p>Click <gui>Color</gui> in the sidebar to open the panel.</p>
    </item>
    <item>
      <p>Select your scanner.</p>
    </item>

      calibration.</p>
    </item>
  </steps>

    not usually need to be recalibrated.</p>
