Service Manual

Theory of Operation

After publication of this service manual, the parts and mechanism may be subject to change for

improvement of their performance.

Therefore, the descriptions given in this service manual may not coincide with the actual machine.

When any change has been made to the descriptions in the service manual, a revised version will be

issued with a revision mark added as required.

Revision mark:

• To indicate clearly a section revised, show to the left of the revised section.

A number within represents the number of times the revision has been made.

• To indicate clearly a section revised, show in the lower outside section of the correspond-

ing page.

A number within represents the number of times the revision has been made.

NOTE

Revision marks shown in a page are restricted only to the latest ones with the old ones deleted.

• When a page revised in Ver. 2.0 has been changed in Ver. 3.0:

The revision marks for Ver. 3.0 only are shown with those for Ver. 2.0 deleted.

• When a page revised in Ver. 2.0 has not been changed in Ver. 3.0:

The revision marks for Ver. 2.0 are left as they are.

5. Copy process

5.1 Copy Process Overview

1. PC Drum

• Made up of an aluminum pipe coated with a photoconductive layer, on which an electro-

static latent image is formed.

2. Drum Charging

• A uniform negative DC charge is deposited across the entire surface of the PC Drum.

3. Photoelectric Conversion

• A CCD sensor is used to convert the image data represented by light reflected off the

original to a corresponding electric signal which, in turn, is output to the IR image pro-

cessing section.

4. IR Image Processing

• The analog electric signal is converted to an 8-bit digital image signal (A/D conversion)

which, in turn, goes through appropriate corrections before being output to the PH image

processing section.

5. PH Image Processing

• After going through corrections, the digital image signal is converted to a corresponding

electric signal (D/A conversion), with which the laser is turned ON or OFF as necessary.

6. Laser Exposure

• The laser beam strikes the surface of the PC Drum, forming an electrostatic latent image.

7. Developing

• Toner negatively charged in the Developer Mixing Chamber is attracted onto the electro-

static latent image changing it to a visible, developed image.

• A developing bias (Vb) is applied to the Developing Roller to prevent toner from being

attracted onto those areas of the PC Drum which correspond to the background areas of

the original.

8. Paper Take-up

• Paper is supplied from the paper feed tray.

9. Bypass Paper Take-up

• Paper is supplied by way of the Manual Bypass, one sheet at a time.

• The optional Multiple Bypass (MB-501), when mounted on the copier, permits continu-

ous paper supply.

ineo 161

ineo 210

Outline

10. Image Transfer

• A DC positive charge is applied to the Image Transfer Roller to transfer the visible image

on the surface of the PC Drum onto the paper.

11. Paper Separation

• The PC Drum Paper Separator Fingers remove paper from the surface of the PC Drum.

• The Charge Neutralizing Plate neutralizes any charge left on the paper.

12. Cleaning

• Residual toner on the surface of the PC Drum is scraped off.

• The toner is then recycled back to the Developing Unit.

13. Main Erase

• The surface of the PC Drum is irradiated with light and any surface potential remaining

there after cleaning is neutralized.

14. Paper Transport

• The paper is transported to the Fusing Unit.

15. Fusing

• The developed image is permanently fused to the paper by the combination of heat and

pressure applied by the Fusing Roller.

16. Paper Exit

• The paper is fed out onto the Exit Tray.

• The optional Job Separator (JS-503), when mounted on the copier, allows a specific tray,

in which paper is fed, to be selected according to the operating mode.

5.2 Image Forming Process

5.3 Drum Charging (Step 1)

• A compact comb electrode is used for drum charging to reduce the amount of ozone pro-

duced and save space. The Drum Charge Corona deposits a charge evenly across the

entire surface of the PC Drum.

• The Scorotron system is used and the grid mesh provided between the corona wire and

the PC Drum ensures that a uniform charge is deposited across the entire surface of the

PC Drum.

Step Process Function

Step 1 Drum charging Forms a charge layer on the surface of the PC Drum.

Step 2 Exposure

Forms an electrostatic latent image on the surface of

the PC Drum.

Step 3 Developing

Changes the electrostatic latent image to a visible,

developed image.

Step 4 Image transfer

Transfers the toner image on surface of the PC Drum to

paper.

Step 5 Paper separating

Separates the paper, onto which the toner image has

been transferred, from the surface of the PC Drum.

Step 6 Fusing Fuses the toner on the paper permanently.

Step 7 PC Drum cleaning Removes toner left on the surface of the PC Drum.

Step 8 Charge neutralizing

Neutralizes any residual charge left on the surface of

the PC Drum after the PC Drum cleaning process.

Step 9 Image Transfer Roller cleaning

Removes toner sticking to the surface of the Image

Transfer Roller after image transfer.

Step 10 Toner recovery

Recovers toner removed during the PC Drum cleaning

process.

5.4 Exposure Process (Step 2)

• The surface of the PC Drum is irradiated with light reflected off the original, which forms

an electrostatic latent image.

5.5 Developing Process (Step 3)

• Toner is attracted onto the electrostatic latent image produced through the exposure pro-

cess, thereby forming a visible, developed image.
