(1) Image Drum Unit

The image drum unit consists of a sensitive drum, a charger, and a developer. The unit forms a toner image on the sensitive drum, using a electrostatic latent image formed by the LED head.

(2) Registration Motor

The registration motor is a pulse motor of 48 steps/rotation, that is two-phase excited by the signal from the Main Control PCB. It drives the hopping and registration rollers via two oneway clutches according to the direction of rotation.

(3) Drum Motor

The drum motor is a pulse motor of 48 steps/rotation that is two-phase excited by the signal from the Main Control PCB and is the main motor of this mechanism.

(4) LED Head

Image data for each dot line from the control board is received by the shift register and latch register. The 2496 LED's (OKIPAGE 6e)/4992 LED's (OKIPAGE 6ex) are driven to radiate the image data on the image drum.

(5) Fuser

The fuser consists of a heater, a heat roller, a thermistor and a thermostat.

The AC voltage from the power supply board is applied to the heater controlled by the

HEATON signal from the control board. This AC voltage heats the heater. The Main Control

PCB monitors the heat roller temperature via the thermistor, and regulates the heater roller to a predetermined temperature (165

°

C) by connecting or disconnecting the AC voltage supply to the heater.

When an abnormal rise of the heater roller temperature takes place, the thermostat of the heater voltage supply circuit becomes active and forcibly cuts the AC voltage supply.

2 - 12

2.5.2

Electrophotographic Process

The electrophotographic processing is outlined below. The electrophotographic printing process is shown in Figure 2-7.

1 Charging

The surface of the image drum is charged uniformly with a negative charge by applying the negative voltage to the charge roller.

2 Exposure

Light emitted from the LED head irradiates the negatively charged surface of the image drum.

The surface potential of the irradiated portion of the image drum surface becomes lower, forming the electrostatic latent image associated with the print image.

3 Developing and toner recovery

When the negatively charged toner is brought into contact with the image drum, it is attracted to the electrostatic latent image by static electricity, making the image visible.

At the same time, the residual toner on the image drum is attracted to the developing roller by static electricity.

4 Transfer

When paper is placed over the image drum surface, the positive charge which is opposite in polarity to that of the toner, is applied to the reverse side by the transfer roller. The toner is attracted by the positive charge and is transferred onto the paper. This results in the transfer of the toner image formed on the image drum onto the paper.

5 Temporary cleaning

Residual toner which remains on the image drum without being transferred is evened out by the cleaning roller and is temporarily attracted to the cleaning roller by static electricity.

6 Fusing

The toner image transferred onto the paper is fused to the paper by heat and pressure.

An electrophotographic process timing chart is shown in Figure 2-8.

Process Operation Descriptions

(1) Hopping and Feeding

Hopping and feeding motions are actuated by a single registration motor in the mechanism as shown below:

Idle gear

Registration motor

Registration roller a

Hopping roller b

Registration gear

Motor gear

Hopping gear

The registration motor turning in direction "a" drives the hopping roller. The registration motor turning in direction "b" drives the registration roller. The registration and hopping gears have one-way bearing, so turning any of these gears in the reverse direction will not transmit the motion to the corresponding roller.

2 - 16

(a) Hopping

1 For hopping, the registration motor turns in direction "a" (CW direction) and drives the hopping roller to advance the paper until the inlet sensor turns on (in this case, the registration gear also turns, but the registration roller is prevented from turning by the one-way bearing).

2 After inlet sensor is turned on by the paper advance, the paper is further advanced to a predetermined distance until the paper hits the registration roller

(the skew of the paper can thus be corrected).

Paper a

Registration roller

Hopping roller

2 - 17

(b) Feeding

1 When hopping is completed, the registration motor turning in direction "b"

(CCW direction) drives the registration roller to advance the paper (in this case, the hopping gear also turns, but the hopping roller is prevented from turning by the one-way bearing).

2 The paper is further advanced, synchronization to the print data.

(2) Charging

Charging is actuated by the application of the DC voltage to the charge roller that is in contact with the image drum surface.

Power supply

Charge roller

Image drum

The charge roller is composed of two layers, a conductive layer and a surface protective layer, both having elasticity to secure good contact with the image drum. When the DC voltage applied by the power supply exceeds the threshold value, charging begins. The applied voltage is proportional to the charge potential, with offset of approximately –550V.

(3) Exposure

Light emitted by the LED head irradiates the image drum surface with a negative charge. The surface potential of the irradiated portion of the image drum drops, forming an electrostatic latent image associated with the image signal.

The image drum is coated with an underlayer (UL), a carrier generation layer (CGL), and carrier transfer layer (CTL) on aluminum base. The organic photo-conductor layer (OPC), comprising CTL and CGL, is about 20

µ m thick.

The image roller surface is charged to about –750 V by the contact charge of the charge roller.

When the light from the LED head irradiates the image drum surface, the light energy generates positive and negative carriers in the CGL. The positive carriers are moved to the

CTL by an electrical field acting on the image drum. Likewise, the negative carriers flow into the aluminum layer (ground).

The positive carriers moved to the CTL combine with the negative charges on the image drum surface accumulated by the contact charge of the charge roller, lowering the potential on the image drum surface. The resultant drop in the potential of the irradiated portion of the image drum surface forms an electrostatic latent image on it. The irradiated portion of the image drum surface is kept to about –100 V.

(4) Developing

Toner is attracted to the electrostatic latent image on the image drum surface, converting it into a visible toner image. Developing takes place through the contact between the image drum and the developing roller.

1 As the toner supply roller rotates while rubbing on the developing roller, a friction charge is generated between the developing roller and the toner, allowing the toner to be attracted to the developing roller (the developing roller surface is charged positive and the toner, negative).

(5) Transfer

The transfer roller is composed of conductive sponge material, and is designed to get the image drum surface and the paper in a close contact.

Paper is placed over the image drum surface, and the positive charge, opposite in polarity to that of the toner, is applied to the paper from the reverse side.

The application of a high positive voltage from the power supply to the transfer roller causes the positive charge inducement on the transfer roller surface, transferring the charge to the paper as it contacts the transfer roller. The toner with negative charge is attracted to the image drum surface, and it is transferred to the upper side of the paper due to the positive charge on the reverse side of the paper.

(6) Fusing

When the image transfer is completed, the toner image is fused to the paper by heat and pressure as the paper with unfused toner image passes between the heater roller and the back-up roller. The heater roller with Teflon coating incorporates a 400W heater (Halogen lamp), which heats the heat roller.

A thermistor which is in contact with the heater roller regulates the temperature of the heater roller at a predetermined level (about 165

°

C). A safety thermostat cuts voltage supply to the heater off by opening the thermostat in the event of abnormal temperature rises.

The back-up roller is held under a pressure of 3.8 kg applied by the pressure spring on each side.

(7) Cleaning

When the transfer is completed, the residual toner left on the image drum is attracted to the cleaning roller temporarily by static electricity, and the image drum surface is cleaned.

(8) Cleaning of rollers

The charge, transfer and cleaning rollers are cleaned for the following cases:

• Warming up when the power is turned on.

• Warming up after the opening and closing of the cover.

• When the number of sheets accumulated reaches 10 or more, and the printout operation ends.

• User initiated.

Changes in bias voltage applied to each roller moves the attaching toner off the roller to the image drum and returns it to the developer.

Cause of error

• The paper is in contact with the inlet sensor when the power is turned on.

• After hopping operation is attempted three times, the leading edge of the paper does not reach the inlet sensor.

• The paper is in contact with at the paper sensor when the power is turned on.

• The leading edge of the paper does not reach the paper sensor within a predetermined distance since the paper has reached the inlet sensor.

• The trailing edge of the paper does not pass over the paper sensor within a predetermined distance after the same has passed over the inlet sensor.

• The leading edge of paper does not reach the outlet sensor within a predetermined distance after the paper has reached the paper sensor.

• The paper is in contact with the outlet sensor when the power is turned on.

• The paper does not pass over the outlet sensor within a predetermined distance after the leading edge of the paper has reached the outlet sensor.

• The paper size check for manual feeding finds that the paper size is free size.

• The size of the paper is monitored by the inlet sensor 1. The paper is not detected by the inlet sensor 1 within predetermined distance.

• The inlet sensor 2 detects that the size of the loaded paper is A4 or larger, or smaller than A4. The detected paper size differs from the paper size set by command or menu.

Cover Open

When the stacker cover is opened, the cover open microswitch on the power/sensor board is turned off to cut +5V supply to the high voltage power supply circuit. This results in the interruption of all high-voltage outputs. At the same time, the CVOPN signal is sent to the control board to notify that the microswitch is off, and the control board carries out the cover open process.

2.8

Toner Low Detection

• Device

The Toner Low Detection device consists of a stirring gear which rotates at a constant rate, a stirring bar and a magnet on the stirring bar. The stirring bar rotation is driven by the link to the protrusion in the stirring gear.

Magnet

Stirring Bar

Protrusion

Stirring Gear

• Operation

Toner Low is detected by monitoring the time interval of the encounter of the magnet set on the sensor lever and the magnet on the stirring bar.

Stirring Gear Section

Operation during Toner Full state

• The stirring bar is rotated due to the mechanical transmission of energy originating from the interlocking with the stirring gear.

• Even when the magnet on the stirring bar reaches the maximum height, the stirring bar is pushed by the stirring gear, since the other end is being dipped in the toner.

Stirring Bar

Toner Sensor

Sensor Plate

Operation during Toner Low state

• When the stirring bar reaches the maximum height, it falls to the minimum height due to its own weight, since there is no resistance provided by the toner on the other side. Because of this, the time interval during which it is in encounter with the magnet of the sensor lever becomes longer. By monitoring this time interval, Toner Low can be detected.

MECHANISM DESCRIPTION

2.1

General Mechanism

The Multi-Purpose Feeder feeds the paper into the printer by receiving the signal from the printer, which drives the pulse motor inside the Multi-Purpose Feeder, and this motion is conveyed to rotate roller-A and B. The paper is delivered from the separator into the printer.

Once delivered into the printer, the paper is then controlled and fed through by pulse motor

(Registration) of the printer.

2.2

Hopper Mechanism

The hopper automatically feeds the printer with the paper being set, single sheet at a time.

After the paper is set in the Multi-Purpose Feeder, the pulse motor moves the paper and a single paper caught by the separator is fed into the printer.

MECHANISM DESCRIPTION

2.1

General Mechanicsm

The High Capacity Second Paper Feeder feeds the paper into the printer by receiving the signal from the printer, which drives the pulse motor inside the High Capacity Second Paper Feeder.

This motion is converyed to rotate the One-way clutch of the hopping shaft assembly. The paper is delivered from the hopper into the printer through the turning of the hopping shaft assembly.

Once delivered into the printer, the paper is then controlled and fed through by pulse motor

(Registration) of the printer.

2.2

Hopper Mechanism

The hopper automatically feeds the printer with the paper being set, single sheet at a time. When the paper is loaded in the paper cassette, it is then transported by the pulse motor.
