2. Newly employed technology

Item Content Remark

1 LED printhead employed • Employment of the 4bit LED provides

16-gradation expressions for each of YMCK.

• Free from mechanical noises which are produced from the unit such as an LSU. Printing is started immediately without waiting for stabilization of the polygon motor speed.

• Lower power consumption than an LSU

2 Oil-less fusing system employed • Development of a new wax-free toner

• The wax-free fusing system provides a simplified structure and improved paper feed capability.

• Notes and remarks can be put on a copy image similar to normal page.

B. Scanner function (Option)

The scanner function is enabled by canceling the product key in the MFP model. This function also requires installation of 256MB expansion memory.

(1) PUSH SCAN

PUSH SCAN is used to send scan data to PC or a file server by the operation on the machine operation panel.

PUSH SCAN has the following three modes:

• SCAN TO E-MAIL (SMTP) Scan data area attached to an E-mail.

• SCAN TO FILE SERVER (FTP) Scan data are sent to a file server by FTP. The URL can be e-mailed simultaneously.

• SCAN TO DESKTOP (FTP) Scan data are sent to the desktop user. (SHARPDESK and the

network scanner tool are required.)

b. Basic operations (PUSH SCAN)

Network protocol TCP/IP, SMTP, FTP, (HTTP) Trial mode Supported by the service diag.

The upper limit is 500 scans (surfaces). Without canceling the product key, scanning functions are enabled. 500 counts in total of color and black-and-white scans. No counter for the trial mode. Resolution level: [lowest] or [lower] key only.

Destination registration 500 items of scan to E-mail from Embedded Web Server + group, and 100itmes of Scan to FTP + Desktop (Max.

600 items can be registered.) Scan to E-mail and group can be registered from the operation panel. A destination name can be set with max. 18 characters in two bytes (or 36 characters in one byte).

An E-mail address can beg set with max. 50 characters in one byte. Address book The static address book stored in MFP is supported. Destination select Selected from the operation panel.

Selection of two or more destinations is allowed. (Only Scan to E-mail)

Transmission to temporary user is available.

Heats and presses toner to fuse it on paper. Silicon rubber rollers are used as the upper and the lower heat rollers. Teflon tube is wound around the upper heat roller. Mechanically separate paper from the heat roller, which was not separated naturally.

Detects the surface temperature of the heat roller. (Keeps the roller surface temperature at a constant level.)

Cuts conduction of the heater lamp when an abnormally high temperature is detected.

(4) Operational descriptions

a. Fusing unit drive

To drive the fusing unit, drive power is transmitted from the drive motor (FUSM) through the connection gear to the upper heat roller gear.

The drive motor (stepping motor) is driven by the motor drive IC in the driver PWB according to the control signal sent from the PCU.

c. Fusing operation

Color toner of YMCK on paper is heated and pressed by the heat rollers to be fused on paper.

At that time, color toner of YMCK is mixed to reproduce nearly actual colors of document images.

Driver PWB

b. Heater lamp drive

The surface temperature detected by the thermistor is sent to the PCU. When the temperature is lower than the specified level, the PCU sends the heater lamp lighting signal to the heater lamp drive circuit in the DC power PWB.

The triac in the heater lamp drive circuit is turned on to apply AC power to the heater lamp, which turns on to heat the heat rollers.

The thermostats are provided as a safety measure to prevent against an abnormally high temperature of the heat rollers.

When the thermostat is opened, the power supply (AC neutral) to the heater lamp is cut off.

FUSMPCU

AR-C262M DESCRIPTIONS OF EACH SECTION 7 - 2

The upper and the lower heat rollers are provided to heat from above and below. This is because it is necessary to heat four layers of toner from above and below and right and left to fuse it on paper.

The upper and lower heat rollers are of silicon rubber. This is because of the following reasons:

1) To provide a greater nip quantity and a higher heating capacity for paper.

2) The soft, flexible rollers press multi-layer toner without deformation to fuse on paper.

3) An even pressure is applied to an uneven surface of multilayer toner.

d. Fusing temperature control

The temperature sensor is provided at the center of the upper and the lower heat rollers.

The temperature sensor at the center detects the heat roller temperature and controls the heater lamp to keep the fusing temperature at the specified level.

The fusing temperature is switched according to the machine condition and paper type selected.

AR-C262M DESCRIPTIONS OF EACH SECTION 7 - 8

(4) Operational descriptions

a. Transfer belt drive

The transfer belt drive power is transmitted from the drive motor (BTM) to the transfer drive roller.

The motor (stepping motor) is driven by the drive signal sent from the PCU.

b. Applying a transfer high voltage to the transfer roller

According to the high voltage control signal from the PCU, the signal is converted into a transfer high voltage control signal with the HV (MC) PWB, and sent to the HV (TC) PWB.

According to each color transfer high voltage control signal, a high voltage is applied to each transfer roller from the transfer high voltage HV (TC) PWB through the connection spring to each transfer roller.

e. Transfer belt unit up and down

In color print, the transfer belt is in contact with four OPC drums. In black and white print, the transfer belt unit moves down so that only the black OPC drum is in contact with the transfer belt.

This up-and-down movement of the transfer belt is performed by the lift-up motor (BLUM), the lift-up cam, and the unit position sensor (BLUD).

When the left cabinet is opened for jam process, the rotating mechanism of the lift-up unit separates all four OPC drums from the transfer belt.

• Transfer belt position for color print The four OPC drums are in contact with the transfer belt by rotation of the cam in the transfer lift-up unit.

YMC

• Transfer belt position for black print Only the black OPC drum is in contact with the transfer belt by rotation of the cam in the transfer lift-up unit.

c. Process control sensor control

The process control shutter is provided on the process control sensor of monochrome (PCSK) and color (PCSC). When the shutter is open (in image density correction and automatic registration), the toner patch formed on the transfer belt is read by the process control sensor, and its information is sent to the PCU.

When the shutter is closed, the calibration sheet is read to perform calibration of the sensor itself.

The shutter operation is controlled by the calibration solenoid (CALS).

d. Belt waste toner full detection

Toner scraped by the belt cleaning blade is transported to the waste toner box by the belt waste toner transport shaft.

When the waste toner box is full, the rotation load of the waste toner transport shaft increases to turn on the waste toner full detection switch with the lever by the torque limiter function.

(4) Operational descriptions

a. Drum cartridge and toner cartridge drive

The drive power for the drum cartridges are transmitted from the drive motor (DM) to the drum gears.

The toner cartridge is driven through the drum gear and the connection gear.

The motor (stepping motor) for black is driven by the drive signal sent directly from the PCU, and the motors color are driven by the drive signals sent from the PCU through the driver PWB.

AR-C262M DESCRIPTIONS OF EACH SECTION 7 - 16

b. LED (writing) unit

Four LED (writing) units are provided for each of Yellow, Magenta, Cyan, and Black.

Each LED (writing) unit converts YMCK dot image data outputted from the ICU PWB into LED light, and radiate the light onto the OPC drum, forming electrostatic latent images on the OPC drum.

Since the position of each LED unit of CMYK is shifted in the paper transport direction, the above operation depends on the relative position and differs in the operating timing.

c. OPC drum section operations

The OPC drum surface is charged negatively by the main charger, and LED light of images are radiated onto the OPC drum surface by the LED (writing) unit to form electrostatic latent images.

layer

When LED light is radiated onto the OPC drum CGL, positive and negative charges are generated. Positive charges generated in the CGL are attracted and moved by negative charges of the OPC drum, and negative charges by positive charges of the aluminum layer of the OPC drum. Therefore, on the OPC drum surface and in the aluminum layer, positive and negative charges are neutralized, reducing the OPC drum surface potential.

Electric charges remain in the areas where LED light is not radiated onto the OPC drum.

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

Charges are disposed in direct proportion to the amount of light received.

Removed residual toner is transported to the waste toner section of the toner cartridge by the waste toner transport screw.

4) The whole surface of the OPC drum is discharged.

By radiating discharge lamp light onto the discharge lens, light is radiated through the discharge lens to the OPC drum surface.

When discharge lamp light is radiated onto the OPC drum CGL, positive and negative charges are generated.

Positive charges generated in the CGL are attracted and moved by negative charges of the OPC drum, and negative charges by positive charges of the aluminum layer of the OPC drum. Therefore, on the OPC drum surface and in the aluminum layer, positive and negative charges are neutralized, reducing the OPC drum surface potential, preparing the drum surface for the new copy cycle.

operations

Electrostatic latent images generated on the OPC drum by the LED (writing) units are converted into visible images by toner.

Rotation of the detection lever connected to the mixing roller is sensed by the sensor (TES) to detect the remaining toner quantity.

OPC drum

CTL

CGL Aluminum layer

Toner in the developing unit is agitated by the mixing roller. By mixing operation, toner is negatively charged due to mechani-

cal friction. The developing bias voltage (negative) is applied to the develop-

ing roller. The diflerence for the voltage potential between the toner and DV

roller surface attracts the toner to the DV roller. In the areas of the OPC drum, when the charge was detected, the

voltage potential difference is greater than the DV roller. Therefore the toner is attracted from the DV roller to the drum.

In the unexposed areas of the drum, the potential on the DV roller created by the bias voltage and therefore the toner to not attracted to those areas of the drum.

Negatively charged toner is attracted and attached to the exposed area on the OPC drum surface where the negative potential was reduced by LED exposure.

On the other hand, in the areas on the OPC drum where exposure was not made, the positive potential is higher than the developing bias voltage, repelling toner.

When the paper tray is set to the maximum length position, the paper length detector is forcibly turned ON. This is to recognize it.

When original is detected in the original tray, EMPS turns ON (no-output level). Original size is determined by DWVR, DLS1 and DLS2. Two operation modes, single-side and duplex, are available. For single-side, after the print SW is turned ON, DFM rotates in the forward direction and the original is transported. (DTM and DEM forward

rotation begins.) REGS detects the leading edge of the fed original (REGS output level HIGH); the original contacts the resist rollers and stops. The DFM reverses its rotation direction , the resist rollers rotate, and the document is transported. The TIMS detects the leading edge of the original, and the DFM turns OFF. After the DTM and DEM stop, the DTM rotates forward, and the transport belt moves. Or, the DFM reverses its direction of rotation, and the

original is sent to the transport section. When the TIMS detects the trailing edge of the original, the DFM stops, after which the DTM (transport belt) also stops. After scanning is

completed, the DTM and DEM turn ON, and the original is discharged. After the DES detects the trailing edge of the original, the DTM and DEM turn OFF (stop).
