1. Test overview.

This test is used to check that the scanner + 120 film carrier are capable of scanning an IR image.
For this, the scanner will scan a B&W film, then will display the image so that the user can accept or reject the test.
If no IR image is scanned, all ADDR system is affected.

2. Test conditions.

This test relates to the 120 film carrier inserted in the scanner.
120 film carrier must to be inserted in the scanner to carry out this test.
A short B&W film must be used for this test (ref 070 100 424A) :
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.
• 120 Pre-Sharp test is accepted to ensure that the IR image is sharpish enough.

4. Test realisation.

Click on RUN pto execute the test. A window will be displayed requiring the insertion of the short B&W film. When the film is inserted (watch for the direction of film), click on OK.
The scanner will scan the first exposure of 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 of is simply to verify that an IR image is visible, and that it is sharp enough.
If these 2 creteria are good, to click on OK then to accept the test while clicking on ACCEPT.

6. Other affected tests.

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

• 120 Ratio RGB-IR.
• 120 Cal encoder 2.
• 120 Cal RGB-IR.
• 120 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, verify the light channel from the IR source til the CCD IR .
• If the image is completely fuzzy : : Redo the test 120 Pre-Sharp (lens adjustment to have a sufficient sharpness ).
