Scanned image data
have black line, white
line, darker image than
the original)
1. Shading data stored in CONTROL
board is not proper to perform an
image process.
1. Perform the
"Shading"
in Sec. 9.3.7 to over-write new data.
2. The dust exists on the Scanning
Glass ((F) or (B)) or its surrounding
(Reference area or others).
1. Wipe off the dust with the roller cleaning paper.
3. Problem with Pixel data from CCD
Board (F) or from image processing
circuit
1. Check the connection and soldering condition of the
following parts.
(1) between CN2001 (CCD Board (F)) and CN1001
(CONTROL Board)
2. Check the soldering condition of the following parts and their
surrounding circuit on the CCD Board (F).
(1) IC2002
(2) IC2003
3. Check the soldering condition of the following parts and their
surrounding circuit on the CONTROL Board.
(1) IC1007 (Gate Array: especially 68th to 71st pins)
(2) IC1004, IC1005 (A/D Conv.)
4. Monitor the following CCD Timing signals on the CN1001.
(1) FCCD_TG: See Fig. 10.1.1.
(2) FCCD_CLK1: See Fig. 10.1.2.
(3) FCCD RS: See Fig. 10.1.3.
(4) FCCD CP: See Fig. 10.1.4.
5. Replace faulty parts or boards.
4. Problem with Pixel data from CCD
Board (B) or from image processing
circuit
1. Check the connection and soldering condition of the
following parts.
(1) between CN2501 (CCD Board (B)) and CN1002
(CONTROL Board)
2. Check the soldering condition of the following parts and their
surrounding circuit on the CCD Board (B).
(1) IC2502
(2) IC2503
3. Check the soldering condition of the following parts and their
surrounding circuit on the CONTROL Board.
(1) IC1007
(Gate Array: especially 73rd, 74th, 79th, and 80th pins)
(2) IC1004, IC1005 (A/D Conv.)
4. Monitor the following CCD Timing signals on the CN1001.
(1) BCCD_TG: See Fig. 10.1.5.
(2) BCCD_CLK1: See Fig. 10.1.6.
(3) BCCD RS: See Fig. 10.1.7.
(4) BCCD CP: See Fig. 10.1.8.
5. Replace faulty parts or boards.
5. Lamp gets dark, or has almost
reached its life expectancy.
(only in case of a darker image.)
1. Perform the
"CCD Level"
test in Sec. 9.3.6 to check the
peak level.
2. Replace an applicable lamp. (Lamp (F) or Lamp (B))
6. Lamp drive circuit (for Front) does
not work properly.
(only in case of darker image)
1. Perform the
"CCD Level"
test in Sec. 9.3.6 to check the
peak level.
2. Check the Lamp Drive Board (F)'s soldering condition and
connection to the Lamp (F).
3. Replace the Lamp Drive Board (F).
7. Lamp drive circuit (for Back) does
not work properly.
(only in case of darker image)
1. Perform the
"CCD Level"
test in Sec. 9.3.6 to check the
peak level.
2. Check the Lamp Drive Board (B)'s soldering condition and
connection to the Lamp (B).
3. Replace the Lamp Drive Board (B).
