Performance of Dust Evasion System Test—detailed results, continued

This is a portion of the ﬁrst image taken. There were streaks both in the image and in the

background.

Conclusion

The scanner’s ability to remove large amounts of dust from the imaging area was observed.

However, there was still a noticeable streak in the image after the dust was removed.

The intent of this test was to run the scanner until there was a visible streak in the image and

disable the scanner. When the scanner was re-enabled the dust detection system was to

detect the dust, clean the imaging area and continue scanning. This test would be repeated

until the Dust Detection System could no longer correct for the dust on the guides.

To speed up the creation of dust, the Dust Creator Tool was used.

During our testing we noticed that there were very visible streaks in the images. When the

scanner was disabled and re-enabled, the Dust Detection System did not detect the dust.

The dust streak grew from 1 pixel wide to about 49 pixels wide. Dust was not detected by the

Dust Detection System using either the ON1 or ON2 settings.

Conclusion

The Dust Detection System did not detect dust that was clearly visible in the image.
