Check whether there is something blocking the light and check the Lamp, Lens, Mirror, and White Color Correction Plate for deterioration or contamination.
1. Turn ON the power and enter the Diag mode. Change the value of NVM [715-030] to "1" and then perform IIT Faulty Parts Diagnosis. After performing the IIT Faulty Parts Diagnosis, select [Change Settings].
2. A 3-digit or 4-digit number is displayed in the [Current Value] field.
3. Check the upper 1 or 2 digits, or the lower 2 digits using the following table and replace the appropriate parts.
Sample Display
110 (3-digit display):
LED Lamp failure and LED Lamp Flexible Print Cable is damaged or has poor contact.
(The first digit "1" in "110" is the upper digit, which indicates the LED Lamp ("0" in "01" is not displayed). The last two digits "10" indicates the LED Lamp Flexible Print Cable.)
1000 (4-digit display):
The LED Lamp Flexible Print Cable is damaged or has poor contact.
(The first 2 digits "10" in "1000" are the upper digits, which indicates the LED Lamp Flexible Print Cable. The lower 2 digits "00" indicates that nothing is applicable (no failure).)
4. After replacing the appropriate parts, change the value of NVM [715-030] to "1" and then perform IIT Faulty Parts Diagnosis. After performing the IIT Faulty Parts Diagnosis, select [Change Settings].
5. Check that the display in the [Current Value] field becomes "0".
6. If the problem persists after performing the above procedure, check the following:
Check for burnt out LED Lamp (DC330 [062-002]). (PL 1.5, PL 1.11)
Check the Flat Cable between the LED Lamp PWB J7001 and the IIT Trans PWB J723 for open circuits, short circuits, and poor contacts (especially, check whether the Flat Cable was inserted in a skewed manner).
The connection between the CCD Lens Assy J701 and the IIT Trans PWB J710 for open circuit, short circuit, and poor contact.
The Flat Cable between CCD Lens Assy J700 and Controller PWB J336 for open circuit, short circuit, and poor contact (especially check whether the Flat Cable was inserted in a skewed manner).
7. If no problem is found, replace the Controller PWB. (PL 35.2) |
