1. Test overview.

This test checks that the ADDR functions correctly.
For this, the scanner will scan a standard film containing scratches and dust and will display the corrected and the none corrected image. The user will judge of the effectiveness of the ADDR.
If the ADDR does not or hardly functions, the customer could complain that the scanner does not remove scratches and dust very well.

2. Test conditions.

This test relates to the 135 Film carrier inserted in the scanner.
The 135 Film carrier must be present in the scanner to carry out this test.
A standard film (short preferably), containing dust or stratches on the first exposure must be used for this test.
The acceptrance of the test is manual.
No parameter is saved.

3. Pre-requirements.

• 135 Sharpness-CoeffG test is accepted so that sharpness in the centre of film is at its maximum.
• 135 Cal V-Offset On Edges test is accepted so that Voffset is correctly adjusted.
• 135 Cal Encoder 2 test is accepted, the RGB - IR shifts must be calibrated.
• 135 Cal RGB IR test is accepted so that the shift of the IR image compared to RGB image is calibrated.

4. Test realisation.

Click on RUN pto carry out the test. A message will be displayed asking for the film to be inserted (first exposure containing scratches and dust). Once the film is inserted, click on OK.
The scanner will scan the first exposure then will display several images :

• The RGB image, allows to go from a 0% correction to a 100% correction to ADDR button efficacity.
• The IR image, check for the presence of dust and scratches.
• Difference between the IR image and RGB image.

Click then on OK then on ACCEPT to accept the test.

Note : the correction is better on Average resolution than into High resolution. Also, the test 135 ADDR uses the Average resolution.

5. Test acceptance.

It is up to the user's discretion to judge of the efficacity of the ADDR. If the image corrected seems correct (scratches and dust erased), the test can be accepted.

6. Other affected test.

None.

7. Trouble shooting.

If the effectiveness of the ADDR is not sufficient :

1. Redo test 135 Cal RGB IR then restart the test.
2. If not, redo tests 135 Cal Encoder 2 then 135 Cal RGB IR then start again the test.
3. If not, check sharpness then redo tests 135 Cal Encoder 2 then 135 Cal RGB IR then start again the test.
