Deadband Test
The Deadband Test is important when using bidirectional printing. It looks for horizontal shifts of one color, not
vertical shifts within a color to verify that alignment for bidirectional printing is performing properly both electrically
and mechanically.
Run the Deadband Test to verify that the printer calibrations (electrical and mechanical alignment) are correct.
1 At the Control Panel select Utility Menu/Service Menu/Calibration Menu/Deadband Test. A test pattern
prints.
2 Use an eye loupe and examine the test pattern – all 6 colors should line up across the entire print.
Note: Verify alignment at 3 primary points: vertically at the right side (observe next to last line), left side (next
to last line), and center area of the printed pattern. It is best to perform this final test on the widest media
possible. Do NOT be too critical of the “Deadband Test” results. The lines should be fairly straight, but they will
almost never be perfectly straight. If there is a large difference then go back to the “Color Deadband” and
the horizontal alignment tests and check the settings.
This is the last step of basic calibration. If you still see horizontal micro-banding then perform the Micro-
banding Calibration procedure in the next section to further minimize micro-banding.
