1. Test overview.

This test is used to check that the scanner + 135 Film carrier are capable of scanning an IR image.
For that, the scanner will scan a B&W film, then will display the image so that the user is able to judge and accept or not the test.
If no IR image is scanned, all of the ADDR system is affected.

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 short B&W film must be used for this test (ref. 070 100 422A):
The acceptance of the test is manual.
No parameter is saved.

3. Pre-requirements.

• CCD IR Test is accepted to ensure that the measurement of the IR signal is correct.
• 135 Pre-Sharp Test is accepted to ensure that the IR image will be sharp enough.

4. Test realisation.

Click on RUN to carry out the test. A message will appear requiring to insert the short B&W film. When the film is inserted (Caution watch for the direction of insertion of film), click on OK.
The scanner will scan the first exposure film then will display the corresponding image.

5. Test Acceptance.

The acceptance of this test is left to the discretion of the user. The goal is simply to check that an IR image is visible, and that it is sharp.
If these 2 criteria are correct, click on OK then accept the test by clicking on ACCEPT.

6. Other affected tests.

If no image is visible or if it is completely fuzzy, the following tests will be affected :

• 135 Ratio RGB-IR.
• 135 Cal encoder 2.
• 135 Cal RGB-IR.
• 135 ADDR.

7. Trouble shooting.

If no image is visible : verify that the measurement of the IR signal by the CCD IR is correct (test CCD IR). If not, check the light channel from the source IR to the IR CCD.

If the image is completely fuzzy : redo the test 135 Pre-Sharp (adjustment of the lens to have a sufficient sharpness).
