Die Alignment Maintenance Routine
The 14 Callisto stationary dies have an overlap of nozzles between each adjacent pair. This
overlap, or alignment, is calibrated at the factory to ensure a seamless die integration. If a dark
or light line appears in the image at a die seam, the die alignment may need further adjusting.
Remember that die alignment is directly related to printhead height. Changing one parameter
may require changes in the other.
Adjust die alignment by printing out a test pattern to determine which die seam(s) need
adjustment. Select the corresponding color and die seams in the interface and adjust the
element to make it darker or lighter. Reprint the test pattern to see the results. If needed print
a sample label to verify the results.
To use the Die Alignment (Narrow Bands) Tool:
- On the Operator panel touch the Support/Tools icon.
- Select Maintenance->Calibrate Printer Manual->Die Alignment
- Touch Quick Print to print the CMYK quality report to identify the color(s) and die
numbers of the issue. This test pattern has the dies numbered and the CMYK colors
separated. Notice that this time you are looking for narrow lines in between the dies.
- Look at the printed report to determine the die(s) and color(s) where a narrow band is
occurring.
- For any narrow band, touch the vertical line in the grid that corresponds to the die
numbers and color for that band. If the narrow band is present across all colors, touch
the space in between the die numbers at the top of the column to select all colors for
that die. A popup box will appear that allows adjustment numbers to be entered.
Figure 8-26. Darken/Lighten Bands
- For dark banks, touch the down arrow to set the number to lighten the band.
- For light banks, touch the up arrow to set the number to darken the band.
TIP: Touch the number keyin to directly edit the number in the popup. An on-screen
keypad will appear.
