Always use the same set of tiles for daily calibration that were used for
the initial color calibration. Do not mix tile sets.
6.4.1 Steps for Tile Calibration
• Remove the requested tile from the box of tiles supplied with the
instrument. Carefully place the tile (with the glossy side down)
squarely on the window. Be sure the tile covers the window.
• Press the color/trash button(s). The software automatically compares
the color of the tile to the standard values recorded for that tile. If
necessary, it adjusts the system constants.
• After the first tile observation is completed, repeat the procedure for
the remaining four tiles.
Once the color head has observed all five tiles, a Pass/Fail screen will
appear. A warning message may appear requesting service if the
reading for the central tile is out of tolerance. Pressing ENTER will
return to the COLOR CALIBRATION MENU. The new calibration values are
saved in the system.
After this initial calibration, use Color/Trash Module Testing to check
calibration each day.
