(8) Ensure that the power sockets and plugs are not cracked or broken in any way. Any such defects should be
repaired immediately. Take care not to cut or damage the power cable or plugs when moving the machine.
(9) Use caution during thunder or lightening storms. Samsung recommend that this machine be disconnected from
the power source when such weather conditions are expected. Do not touch the machine or the power cord if it
is still connected to the wall socket in these weather conditions.
(10) Avoid damp or dusty areas, install the printer in a clean well ventilated location. Do not position the machine
near a humidifier. Damp and dust build up inside the machine can lead to overheating and cause a fire.
(1 1) Do not position the printer in direct sunlight. This will cause the temperature inside the printer to rise possibly
leading to the printer failing to work properly and in extreme conditions could lead to a fire.
(12) Do not insert any metal objects into the machine through the ventilator fan or other part of the casing, it could
make contact with a high voltage conductor inside the machine and cause an electric shock.

1.4 Super Capacitor or Lithium Battery Precautions
1. Exercise caution when replacing a super capacitor or Lithium battery. There could be a danger of explosion and
subsequent operator injury and/or equipment damage if incorrectly installed.
2. Be sure to replace the battery with the same or equivalent type recommended by the manufacturers.
3. Super capacitor or Lithium batteries contain toxic substances and should not be opened, crushed, or burned for
disposal.
4. Dispose of used batteries according to the manufacturer’s instructions.
1.3 ESD Precautions
Certain semiconductor devices can be easily damaged by static electricity . Such components are commonly called
“Electrostatically Sensitive (ES) Devices”, or ESDs. Examples of typical ESDs are: integrated circuits, some field
effect transistors, and semiconductor “chip” components.
The techniques outlined below should be followed to help reduce the incidence of component damage caused by
static electricity.
Caution >>Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
1. Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain off any
electrostatic charge on your body by touching a known earth ground. Alternatively, employ a commercially available wrist strap device, which should be removed for your personal safety reasons prior to applying power to the
unit under test.
2. After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface, such as
aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity of the assembly .
3. Use only a grounded tip soldering iron to solder or desolder ESDs.
4. Use only an “anti-static” solder removal device. Some solder removal devices not classified as “anti-static” can
generate electrical charges sufficient to damage ESDs.
5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to damage ESDs.
6. Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most
replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a comparable conductive material.
7. Immediately before removing the protective shorting material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed.
8. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until completely plugged or soldered into the circuit.
9. Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the brushing
together of clothing fabric and lifting one’s foot from a carpeted floor, can generate static electricity sufficient to
damage an ESD.

4.2 System Layout
SCX6220/6320F can be divided into the following main constituent parts: Main Controller, Operator’s Panel,
PC Interface, Scanner, DADF, Line Interface and Power Supply. The Main Controller uses the SPGPm
processor. The Operator’s panel (OPE) and the DADF each have their own MICOM which communicates
serially with a UART built into the SPGPm processor. The Scanner uses the CIP4e processor to control the
CIS. The Line Interface is an FM336 integrated with the Main Board which communicates with the LIU at
speeds up to 33.6Kbps.
The Power Supply has both the SMPS and HVPS integrated on one PBA.
4.2.1 Feeding section
There is a universal cassette which automatically loads paper and the manual feed which supplies paper
single sheet at a time. The cassette has a friction pad which separates paper to ensure single sheet feeding, and it has a sensor, which checks when the paper tray is empty.
- Feeding Method: Universal Cassette Type
- Feeding Standard: Center Loading
- Feeding Capacity: Cassette-550 sheets (75g/m2 , 20lb paper standard)
- Multi-function tray: 100 sheet (75g/m2 , 20lb paper standard.)
- Paper detecting sensor: Photo sensor
- Paper size sensor: None
- Driven by gearing from the main motor
4.2.2 Transfer Ass’y
This consists of the PTL (pre-transfer lamp) and the Transfer Roller. The PTL shines a light onto the OPC
drum This lowers the charge on the drum’s surface and improves transfer efficiency.
The transfer roller transfers toner from the OPC drum surface to the paper.
- Life span: 100,000 sheets (in 15~30°C)
4.2.3 Drive Ass’y
- Gear driven power unit. The motor supplies power to the paper feed unit, the fuser unit, and the
toner cartridge.
- Duplex motor drives output roller for forward and reverse functions.
- DADF Unit : the DADF has its own MICOM which controls the paper feed motors.
The two motors are, like the printer drive motors, used to feed the paper through the ADF
mechanism. The ADF duplex motor is used for reversing the paper feed for double sided
originals. Both DADF motors operate a a maximum of 2940pps.

4.2.5.2 CCD Imager Control Specification
• CCD Image sensor uses +5V Power and Inverter uses +24Vpower.
- CCD Max. Driving Frequency : 10MHz
- CCD Line time : 0.68ms
- White Data Output Voltage : 0.7V°æ0.5V (Mono Copy, 0.68ms/line)
- Maximum Inverter Current : 600 mA Max.(Power +24V)
4.2.4 Fusing
The temperature change on the heat roller’s surface is measured using a Thermistor. The resistance of the
Thermistor changes as the temperature changes. The value of the resistance is measured using an A to D
converter and the value is sent to the processor. The processor controls the AC power to the heat coil. If
the processor decides that the temperature is out of range an error message is displayed on the KCD
display. Refer to the table below.
Heat Coil Method
Error Description
Open heat error When preheating, it has been lower than 68°C over 15 seconds.
Lower heat error • After finishing the preheating process, the fuser has not reached 100°C (preheating stop
temperature) within 15 seconds of the temperature reaching 68°C.
• Printing
1) When the main motor is on and after 0.92 second, it has not reached 160°C
within 20 seconds.
2) After the second consecutive page, the fuser has been 20°C lower than the fusing
temperature for more than 4 seconds.
Over heat error This error is not displayed immediately when the fuser reaches 220°C.
The temperature is checked after 3 seconds. If it is over 240°C, it is error.
If the temperature has been higher than 220°C for more than 25 seconds, it is an error
even though the temperature doesn't reach 240°C.
