1. Problem with Pixel data from
CCD (F) Board 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 of their surrounding circuit on the CCD Board (F).
(1) IC2002
(2) IC2003
3. Check the soldering condition of the following parts
and of 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.

1. The surface of Scanning Glass
(B) is dirty.
Clean the surface with Roller Cleaning Paper.
2. The Scanning Glass (B) is not
attached to the scanner
properly.
1. Check the condition of the glass
attachment.
2. Reattach the glass (See 8.2.8.)
3. Lamp (B) does not light or gets
dark.
1. Perform the
"Lamp ON/ OFF"
test in Sec. 9.4 to
check whether the Lamp (B) lights or not.
2. Check whether control signals are supplied to lamp
(B) drive circuit (Lamp Drive Board (B)), normally.
(1) Connection between CN1007 (CONTROL Board)
and Lamp Drive Board (B)
(2) Monitor the following signals, executing
"CCD
Level"
test in Sec. 9.3.6.
• CN1007-6th (FLAMP_ON): Approx. +3 V
• CN1008-7th: +16 V
3. Check the Lamp Drive Board (B)'s soldering condition
and the connection to the Lamp (B).
4. Check whether the Lamp (B) is damaged, or is
broken.
5. Replace faulty parts or board.
4. Problem with Pixel data from
CCD (B) Board or from image
processing circuit
1. Check the connection and soldering conditions
between CN2501 on CCD Board (B) and CN1002 on
CONTROL Board.
2. Check the soldering condition of IC2502, IC2503, and
their surrounding circuit on the CCD Board (B).
3. Check the soldering condition of IC1007 (Gate Array:
especially 73rd, 74th, 79th, and 80th pins) and of its
surrounding circuit on the CONTROL Board.
4. Check the soldering condition of IC1004, IC1005 (A/D
Conv.), and their surrounding circuit on the
CONTROL Board.
5. 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.
6. Replace faulty parts or boards.
