1 GENERAL PRECAUTIONS
1.1. Safety Precautions
1. Before servicing, unplug the power cord to prevent electrical shock hazard.
2. When replacing parts, use only manufacture’s recommended components for safety.
3. Check the condition of power cord. Replace if wear or damage is evident.
4. After servicing, be sure to restore the wire dressing, insulation barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, perform the following electrical tests to prevent shock hazard.
6. The power supply unit in this scanner contains dangerous levels energy.
1.2. Electrical Tests
1. Unplug the power cord and check for continuity between the earth ground connection on the plug and the metal cabinet.
There should be zero ohm resistance found.
2. With the unit unplugged, short the AC Live-Neutral of the plug with a jumper wire.
3. Turn ON the power switch.
4. Measure the resistance value with an ohmmeter between the jumpered AC plug and each exposed metal cabinet part, such
as screwheads, etc.
Note
Some exposed parts may be isolated from the chassis by design. They read infinity.
5. If the measurement is less than 1 MΩ, there may be a danger of electric shock.
Note
This hazardous condition must be corrected before the unit is returned to the end user.
1.3. Standard for Repair Service
Repair service shall be provided in accordance with repair technology information such as service manual
so as to prevent fires, injury or electric shock, which can be caused by improper repair work.
1. When performing repairs, neither the products nor its parts or components shall be modified.
2. If cable assembly is supplied as the smallest unit when servicing, make sure to replace
the cable assembly.

5
1.4. For Service Technicians
ICs and LSIs are vulnerable to static electricity.
When repairing, the following precautions will help to prevent recurring malfunctions.
1. Cover plastic parts with aluminum foil.
2. Ground soldering irons.
3. Use a conductive mat on the worktable.
4. Do not hold IC or LSI pins with bare fingers.
1.5. About Lead Free Solder (PbF: Pb free)
Note
•In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder
that contains lead.
•We will use PbF when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn),
Silver (Ag), and Copper (Cu).
•This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and
repair work we suggest using the same type of solder.
Distinction of PbF PCB
•PCBs manufactured using lead free solder will have a PbF stamp on the PCB.
Caution
•PbF solder has a melting point that is 50 °- 70 °F, (30 °- 40 °C) higher than Pb solder.
Use a soldering iron with temperature control and adjust it to 700 °±20 °F (370 °±10 °C).
• Exercise care when using higher temperature soldering irons: Do not heat the PCB for too long time in order to
prevent solder splash or damage to the PCB.
•PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100 °F (600 °C).
•When applying PbF solder to double layered boards, check the component side for excess solder which may flow onto
the opposite side (See figure below).
1.5.1. Suggested Pb free solder
We recommend you to use the following solder when re-soldering components for repair. Before using other Pb free solder than the
following solder, make sure to confirm that the solder maker (you use) has the license agreement for Pb free solder.

4.5. DIMM Module Extension
A maximum of 1024 MB (total size for front and back sides) extended memory may be required depending on the combination of
the paper size, mode, and resolution. To determine how much extended memory is required for a certain configuration, refer to
Fig. 4.5.1 and Fig. 4.5.2.
Note 1:
If configurations requiring a lot of memory (high resolution, color mode, etc.) are used with
KV-S5055C Series, the scanning will be suspended intermittently while the data is
being transferred to the computer.
As a result, the images may be disrupted slightly due to the effect of suspending the scanning.
In cases like this, the image quality will be improved by installing additional memory in the scanner.
To determine the amount of memory that is required to avoid suspending the scanning, refer to Fig.4.5.1. and Fig.4.5.2.
Note 2:
Originally, CONTROL Board has 32 MB memory built in.
Note 3:
For the additional memory, the scanner requires the same type of memories for each side (Front and Back)
to be installed at the same time. (For example: “128” means that you must install 128 MB of memory for front-side
scanning and 128 MB of memory for back-side scanning.)
Note 4: Recommended memory
(1) 144 pin SDRAM (Unbuffered SO-DIMM)
(2) Non ECC
(3) + 3.3 V ± 0.3 V power supply
(4) Frequency / CAS Latency: 100 MHz / CL=2 or 133 MHz / CL=2
(5) Support for Full Page Burst
(6) Memory size: 128 MB, 256 MB, or 512 MB
(7) Height: Less than 31.75 mm (1.25 in.)
Note 5: “X”
“X” in the Fig. 4.5.1 and Fig. 4.5.2 means the scanning will be suspended intermittently (START/STOP function
will operate.) even if the maximum amount of memory (total 1024 MB) is installed.
