2.3 Scanning Section

2.3.1 ADF section

When a document is placed into the document feeder, Document Sensor 1 (DS1) is activated and you will hear the short beep. The width of document is detected by ODB4, ODA3, DB4 and DA3 sensors and length of document is detected by DADFA3 and DADFLEG sensors.

The document will be transferred when either the start or copy key is pressed. Document separation is the process that allows a multi-page document to go through the scanner one page at a time. Separation occurs through the action of the separator roller and separator pad. As shows in the illustrations, documents in the feeder are pressed against the separator roller. The bottom document is separated from the remaining documents by the friction of the separator pad. Following document separation, the feed roller causes the document to advance. As it advances, the leading edge of the document activates the Document Sensor 2 (DS2) sensor. Once DS2 is activated, the feed roller continues to rotate until the document reaches the scan wait position. The machine uses the distance from DS2 to the scan wait position and the diameter of the feed roller to determine the number of rotations necessary to feed the document to the scan wait position.

When the document reaches the scan wait position, the light from the scanner lamp strikes the face of the document and is reflected into the lens through mirrors A, B, and C. In case the light intensity along the length of the scanner lamp is not uniform, shading compensation is provided to ensure even illumination. As the reflected image passes through the lens, it is focused onto the charged coupled device (CCD). The CCD then converts the dark and light areas of the image into electrical impulses, or image data. When there are following pages, DSS detects the end of the former page and the next page will be transferred. When DS2 detects the trailing edge of the document, the image signal output is turned off. The scanner continues to remain active for a few more seconds in case there is another document to follow. The scanned document is discharged through the document exit by the exit roller.

When scanning the back side of the document, the leading edge of the document will be detected by the Document Sensor DSS. It will be scanned by CIS at the scan wait position. When DSS detects the trailing edge of the document, the scanner continues to remain active for a few more seconds, and turn off.

2.3.2 FBS section

Light reflected from the original passes through three mirrors and a lens to form a reduced image on the CCD Sensor as the Scanner is moved by the Scanner Motor. The CCD sensor converts the light pattern (image data) into an electrical image signal. The electrical image signal is then output to the Main Board.

1 Reflector Tape When a book or other bound original is copied, the paper in the area near the binding generally fails to come flush against the glass, so that the copy of these areas is generally too dark. The Reflector Tape reduces this problem by reflecting light from the Exposure Lamp onto these areas of the original.

2 Exposure Lamp A fluorescent lamp is used to illuminate the original.

3 Mirror A Directs the reflected light from the original to the Mirror B.

2.3.1.2 Original Size Detection

When the machine is in Auto Paper or Auto Size, the original length detecting sensor mounted in the FBS section receive light reflected off the original to allow the machine to determine the original length size. And the CCD detects original width by reflecting light from the Exposure Lamp.

The copier CPU affirms and resets the readings of the original size at the following timings. Takes size readings: When the BIS sensor is deactivated. Affirms size readings: When the Start key is pressed with the BIS sensor activated or the APS sensor deactuated. Resets size readings: When the APS sensor is deactuated.

2.3.1.4 Mirror Carriage A and Mirror Carriage B Moving Mechanism

During a scan, the Mirror Carriage A projects an even amount of light from the Exposure Lamp onto the

entire surface of the original. The light is reflected from the original to the Mirror A of the Mirror Carriage A and then to the Mirror B and Mirror C of the Mirrors Carriage B.

The Mirror Carriage A is driven by the FBS Motor and front and rear Scanner Drive belts. Scanner speed is determined by the set zoom ratio in reference to the full size mode. The Mirror Carriage A is at home position when Scanner Home Position Sensor is blocked. This

position serves as the reference for the scan motion. The Mirror B and Mirror C are mounted to their holder at right angles to each other. They direct the light

reflected off the Mirror A through the lens to the CCD. The Mirror Carriage B is also moved by the Scanner Drive belts and pulleys driven by the FBS Motor. It

travels at a speed half that of the Mirror Carriage A, thereby keeping constant the optical path length between the Original Glass and lens.

1 PC Drum Changes the image of the original projected onto the surface of the drum to a corresponding

electrostatic latent image. 2. Drum Charging Generates a negative DC charged layer on the surface of the PC Drum. 3. Photoelectric Conversion Section The CCD converts the light reflected off the original to a corresponding electrical signal and outputs it to

the IR image processing section. 4. MFB2 Board Converts the electrical signal to a corresponding 8-bit digital image signal, makes various corrections,

and outputs the results to the memory. Compresses and stores in memory the digital image signal, and then outputs it to the PH image

processing section. After going through necessary corrections, the digital image signal is converted to a corresponding

analog signal, based on which the intensity of the laser light is controlled. 5. Laser Exposure A laser beam strikes the surface of the PC Drum, creating an electrostatic latent image. 6. Development Negatively charged toner adheres to the latent image on the PC Drum surface, creating a visible image. AC/DC negative bias voltages are applied to the Sleeve/Magnet Roller, thereby preventing toner from

sticking to the background. Toner scraped off by the cleaning mechanism is recycled. 7. Paper Feed Feeds sheets of paper from the appropriate paper source. 8. Manual Bypass Feeds sheets of paper from the Manual Bypass Tray. 9. Image Transfer A positive charge is applied to the Image Transfer Roller to transfer the visible image on the surface of

the PC Drum onto the paper.

2-15

10. Paper Separation The PC Drum Separator Fingers remove paper from the surface of the PC Drum. 11. Cleaning Residual toner is scraped off the surface of the PC Drum. The toner is then recycled back to the Developing Unit. 12. Erase The PC Drum is exposed to light, which effectively neutralize any residual charge on the surface of the

PC Drum. 13. Fusing Heat and pressure applied by the Right and Left Fusing Rollers fuse toner on the paper. 14. Paper Exit Feeds paper out of the copier onto the Exit Tray.

resolutions. To shorten the First copy out time, the motor starts before the print direction. It starts when the document is set or when a key is pressed. When there is no print direction, it stops after a while.

2-18

The signal output from the Master Board triggers the firing of the laser. The laser beam travels to the Polygon Mirror, lens, and SOS Mirror to eventually hit the SOS Sensor, which generates an SOS signal.

The SOS signal determines the laser emission timing for each line in the main scanning direction.

The shutter between the PH and Drum closes automatically when the Drum is removed.

This machine employs a spent toner recycling mechanism. The Cleaning Blade which is held pressed against the surface of the PC Drum scrapes residual toner off the surface.

The waste toner is conveyed by Spent Toner Feed Roller to the Spent Toner Recycling Duct and eventually back to the Developer Mixing Chamber.

Any potential remaining on the surface of the PC Drum is neutralized by both light from the Erase Lamp and a DC negative voltage applied by the Charge Neutralizing Sheet.

2.4.5 Toner Unit

2.4.5.1 Toner drive mechanism

The IU motor provides the drive for replenishing toner from the Toner Bottle to the Sub Hopper and to the Developing Unit.. There is no motor provided for the exclusive use of the Toner Bottle. The transfer is controlled by the main hopper toner solenoid and sub hopper toner solenoid. The Toner bottle home position is also controlled by the main hopper toner solenoid, and by a ratchet.

2.4.5.2 Toner Replenishing Mechanism

Toner Replenishing Control (from Toner Bottle to Sub Hopper) A reed switch in the Sub Hopper is used to detect a Toner Empty Condition. When the Sub Hopper Toner Empty Switch is turned ON, the Sub Hopper Toner Solenoid is energized, which causes the Toner Bottle to start turning.

Toner Near Empty Detection A toner near empty condition is detected when the Toner Bottle has turned 30 times continuously. At this time, a corresponding message is displayed on the Control Panel, but a new copy cycle can still be initiated.

Toner Replenishing Control Toner/Carrier (T/C) ratio of the toner in the Developing Unit is detected based on the output produced by the ATDC Sensor. The standard T/C ratio is 14.5% and toner replenishing sequence as shown in the below table is carried out according to the detected T/C ratio. When the T/C ratio becomes 10% or less, the copier will enter the T/C recovery mode. If the T/C of 19% or higher, or 7% or less is detected, a ATDC Sensor failure occurs and a malfunction code is displayed.

When the copier enters the T/C recovery mode, the IU Motor is energized to carry out the toner replenishing sequence for a maximum 150 sec. If the T/C ratio is not recovered to 14% or higher even when the I/U Motor has been energized for 150 sec., a toner empty condition results and the initiation of a new copy cycle is inhibited.

When the T/C ratio has been recovered to 14%, toner in the Developing Unit is agitated for 60 sec. and it then becomes possible to start a new copy cycle.

2.4.6 Image Transfer Section

A charge is applied to the Image Transfer Roller to transfer the toner image formed on the surface of the PC Drum onto the paper.

The image transfer current is controlled according to the size and type of paper, B/W ratio of the original, and whether the copy cycle is 1-sided or 2-sided.The surface of the Image Transfer Roller is cleaned by applying the same negative polarity as the toner.

When servicing, the Image Transfer Roller Unit is re
