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 eld 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 classied as “anti-static”

can generate electrical charges sufcient to damage ESDs.

5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufcient 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 oor, can generate static
electricity sufcient to damage an ESD.

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 manufacturer.

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 manufacture? instructions.

2.3.3.5.1 Scanning Technology

1) Color Separation : Single-Pass color separation

Color separation is done with transmissive color lters put over the CCD elements themselves as part of

CCD manufacturing process. The CCD used in CLX-8380ND Series has three rows of imaging elements.

Each row has a color lter directly over the CCD elements, one row red, one green, and one blue.

2) Image Signal Input :
The output signal of CCD is designed for being ADC in S4L9335X through Bypass-Cap, and then

processing through the Signal which is dened between S4L9335X and CIP4.
It uses CDS (Correlated Double Sampling) which implement double Sampling for black level and image by
using signal of CIP4E, when AFE receives each pixels.

3) Image Processor :
It reads pixel data of CCD (Charge Coupled Device) by 600dpi Line, and in accordance with the mode set

from CIP4, said data is experiencing Error Diffusion Algorithm in mode or stored at Scan Buffer through
DMA without Halftoning Algorithm in PC Scan mode. At this time, both above modes conduct processing
after Shading Correction and Gamma Correction.

4) Optical System: Lens Reduction type All-In-One( Scanning Lamp + Lens + CCD Image sensor)

5) Light Source : Xenon Lamp

3.2 Disassembly and Reassembly

3.2.1 General Precautions on Disassembly

When you disassemble and reassemble
components, you must use extreme caution. The
close proximity of cables to moving parts makes
proper routing a must.
If components are removed, any cables disturbed
by the procedure must be restored as close as
possible to their original positions. Before removing
any component from the machine, note the cable
routing that will be affected.

Whenever servicing the machine, you
must perform as follows:

1. Check to verify that documents are not stored in

memory.

2. Be sure to remove the toner cartridge before you

disassemble parts.

3. Unplug the power cord.

4. Use a at and clean surface.

5. Replace only with authorized components.

Releasing Plastic Latches

Many of the parts are held in place with plastic
latches. The latches break easily; release them
carefully.
To remove such parts, press the hook end of the
latch away from the part to which it is latched.

6. Do not force plastic-material components.

7. Make sure all components are in their proper

position.
