C. Operational descriptions

The OPC drum surface is negatively charged by the main charger. The laser beam images are radiated to the OPC drum surface by the laser unit to form latent electrostatic images.

1) The OPC drum surface is negatively charged by the main charger.

3) After transfer operation, remaining toner is removed by the cleaning blade.

When LD lights are radiated to the OPC drum CGL, negative and positive charges are generated.

Positive charges generated in CGL are attracted to the negative charges on the OPC drum surface. On the other hand, negative charges are attracted to the positive charges in the OPC drum aluminum layer.

Therefore, positive charges and negative charges are balanced out on the OPC drum and in the aluminum layer, reducing positive and negative charges to decrease the OPC drum surface voltage.

Electric charges remain at a position where LD lights are not radiated.

As a result, latent electrostatic images are formed on the OPC drum surface.

Residual toner removed from the OPC drum surface is transported to the recycle toner collection section in the toner cartridge by the waste toner transport screw.

Fusing roller (Pressing)

The fusing heat roller (heating) is provided with two heater lamps, which heat the fusing roller to fuse toner onto paper.

The fusing rollers (pressing) are made of silicon rubber because of the following reasons and purpose.

1) Paper is separated upward. (Since the fusing roller (heating) is of higher hardness, the fusing roller (pressing) is deformed to separate paper upward.)

2) The nip quantity is increased to increase heat capacity for paper.

3) By pressing paper with the flexible roller, toner is fused without deformation.

(4) Fusing temperature control

The temperature sensor is provided at the center of the fusing roller (heating).

The roller temperature is detected by the thermistor sensor, and the heater lamp is controlled so that the temperature is maintained at the specified level.

In addition, the fusing temperature is switched according to the kind of paper.

MX-M350/M450 N/U MAINTENANCE AND DETAILS OF EACH SECTION 7 - 35

3. Paper transport in duplex printing (with AR-DU3/DU4 installed) (1) Switchback operation and paper exit to the left tray

1) Paper transported from the fusing section is sent to the paper exit section of the machine.

2) When the male bin stacker (AR-MS1) or the finisher (AR-FN5) is installed, the paper entry gate solenoid (FGS) selects the paper entry gate to discharge paper outside the machine.

3) The paper exit sensor (POD2) detects the rear edge of paper, and the paper exit motor (POM) is rotated reversely.

4) Paper is taken into the machine again, passed over the reverse gate, and transported to the duplex unit.

5) When duplex printing is made, the ADU gate solenoid switches to the upper side of the ADU paper exit gate to switch the paper path to the ADU.

6) When paper is discharged to the left tray or when paper is transported to the console finisher (AR-FN7), the ADU gate solenoid switches to the upper side of the ADU paper exit gate to switch the paper path to the ADU.

(2) Paper transport speed in duplex printing

The transport speed may be doubled in duplex printing depending on the paper position. The positions of double speed are as follows:

1) From when the rear edge of paper passes the fusing section to when switchback operation is started.

2) From switchback operation, after the lead edge of paper passes APPD1, until a certain amount is transported.

3) After that, paper is stopped at the ADU paper feed position, and fed to the laser printer again.

4. Transport with AR-FN6 installed

The AR-FN6 is provided with the decurler to improve alignment capability of finishing. The decurler makes decurling against curling of paper by means of the difference in rigidity of the upper roller (metal) and the lower roller

(sponge).

A. General

There are following three methods of scanning documents in this machine.

a. Place a document on the table glass. The copy lamp unit is

operated to radiate copy lamp light onto the document, scanning the document with the CCD.

b. The SPF feeds a document. The lamp illuminates the docu-

ment and the image is scanned into the CCD that converts it from A/D.

c. The SPF feed a document. The LED's of the CIS unit (attached

to the SPF) aluminates the back side of the document. The CIS scans the information.

C. Operational descriptions

(1) CCD/lens unit

This machine employs the reduction optical-type line CCD (Charge Coupled Device) of scan resolution of 600dpi and 7450 pixels. CCD scan is performed by shifting the scan positions sequentially by the carriage unit (lamp and mirror) scan or moving the document with

the SPF. Lights reflected by the document are reflected by each mirror to form images on CCD elements through the reduction-type lens. The CCD

converts the optical energy into electrical energy (analog). (Photoelectric conversion)

(2) CIS unit

The image sensor which scans back document images is attached to the SPF. The close-contact type image sensor (Contact Image Sensor) with scan resolution of 600dpi and 7196 pixels is employed.

For the CIS to scan documents, the scan position is sequentially shifted by shifting the document by the SPF, and the LED light in the unit is radiated to the back of the document, and photo energy is converted into electric energy (analog signal).

MX-M350/M450 N/U MAINTENANCE AND DETAILS OF EACH SECTION 7 - 48

(3) Image signal flow

The image signal converted into electric energy (analog signal) is A-D converted on the CCD PWB. Image processes such as white balance and shading correction are performed on the scanner control PWB. The image signal is then sent through the mother board to the MFP control PWB.

In the MFP control PWB, image process is performed according to the setting content of the operation panel. The image data are converted into laser lighting signals (VIDEO signals), and sent through the mother PWB and the PCU to the LSU (Laser Scan Unit).

In the LSU, the VIDEO signals are converted into laser beams, which are radiated onto the drum.

(4) Carriage (lamp unit) shift (scan) speed

The carriage scan speed depends on the copy magnification ratio. Speed up to 171% = 110mm/s Speed of 172% - 400% = 55mm/s
