CAUTION

This product is a class 1 laser product that complies with 21CFR 1040 of the CDRH standard and
IEC825. This means that this machine does not produce hazardous laser radiation. The use of controls,
adjustments or performance of procedures other than those specified herein may result in hazardous
radiation exposure.

This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved
on the eye’s retina, there is the danger of spot damage to the retina.

The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of
servicing.

1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a
unit, not as individual parts.

2) Do not look into the machine with the main switch turned on after removing the developer unit, toner
cartridge, and drum cartridge.

3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected
when removing and installing the optical system.

4) The middle frame contains the safety interlock switch.

Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

Be careful in handling the copier as follows to maintain the perfor­mance of this copier.

Do not drop the copier, subject it to shock or strike it against any
object.

Do not expose the drum cartridge to direct sunlight.
Doing so will damage the surface (green portion) of the drum car-

tridge, causing poor print quality.

• poorly ventilated

• subject to extreme temperature or humidity changes, e.g., near
an air conditioner or heater.

The copier should be installed near an accessible power outlet for
easy connection.

Be sure to connect the power cord only to a power outlet that
meets the specified voltage and current requirements.

Also make certain the outlet is properly grounded.
Be sure to allow the required space around the machine for servic-

ing and proper ventilation.

8" (20cm)

2. Outline of print process

This printer is a non-impact printer that uses a semiconductor
laser and electrostatic print process. This printer uses an OPC
(Organic Photo Conductor) for its photoconductive material.

First, voltage from the main corona unit charges the drum surface
and a latent image is formed on the drum surface using a laser
beam. This latent image forms a visible image on the drum surface
when toner is applied. The toner image is then transferred onto the
print paper by the transfer corona and fused on the print paper in
the fusing section with a combination of heat and pressure.

Step-1: Charge
Step-2: Exposure

∗ Latent image is formed on the drum.

Step-3: Developing

Latent image formed on the drum is then changed into
visible image with toner.

Step-4: Transfer

The visible image (toner image) on the drum is transferred
onto the print paper.

Step-5: Cleaning

Residual toner on the drum surface is removed and col­lected by the cleaning blade.

Step-6: Optical discharge

Residual charge on the drum surface is removed, by
semiconductor laser beam.

3. Actual print process

Step-1: DC charge

A uniform negative charge is applied over the OPC drum surface
by the main charging unit. Stable potential is maintained by means
of the Scorotron charger.

Positive charges are generated in the aluminum layer.

Step-2: Exposure (laser beam, lens)

A Laser beam is generated from the semiconductor laser and con­trolled by the print pattern signal. The laser writes onto the OPC
drum surface through the polygon mirrors and lens. The resis­tance of the OPC layer decreases for an area exposed by the laser
beam (corresponding to the print pattern signal). The beam neu­tralizes the negative charge. An electrostatic latent image is
formed on the drum surface.

Step-3: Developing (DC bias)

A bias potential is applied to the MG roller in the two component
magnetic brush developing method, and the toner is charged neg­ative through friction with the carrier.

Non-image area of the drum surface charged with negative poten­tial repel the toner, whereas the laser exposed portions where no
negative charges exist, attract the toner. As a result, a visible
image appears on the drum surface.

Step-4: Transfer

Step-5: Separation

Since the print paper is charged positively by the transfer corona, it
is discharged by the separation corona. The separation corona is
connected to ground.

Step-6: Cleaning

Toner remaining on the drum is removed and collected by the
cleaning blade. It is transported to the waste toner collecting sec­tion in the cleaning unit by the waste toner transport roller.

AL-2040CS COPY PROCESS 6 - 3

Step-7: Optical discharge (Semiconductor laser)

Before the drum rotation is stopped, the semiconductor laser is
radiated onto the drum to reduce the electrical resistance in the
OPC layer and eliminate residual charge, providing a uniform state
to the drum surface for the next page to be printed.

When the electrical resistance is reduced, positive charges on the
aluminum layer are moved and neutralized with negative charges
on the OPC layer.

Semiconductor laser

Charge by the Scorotron charger

Function

The Scorotron charger functions to maintain uniform surface
potential on the drum at all times, It control the surface potential
regardless of the charge characteristics of the photoconductor.

Basic function

A screen grid is placed between the saw tooth and the photocon­ductor. A stable voltage is added to the screen grid to maintain the
corona current on the photoconductor.

As the photoconductor is charged by the saw tooth from the main
corona unit, the surface potential increases. This increases the
current flowing through the screen grid. When the photoconductor
potential nears the grid potential, the current turns to flow to the
grid so that the photoconductor potential can be maintained at a
stable level.

Start

1) Because the grid potential is at a low level, the drum potential
is at about -400V. (Carrier may not be attracted though the car­rier is pulled towards the drum by the electrostatic force of ­400V.

2) Developing bias (-400V) is applied when the photoconductor
potential is switched from LOW to HIGH.

3) Once developing bias (-400V) is applied and the photo con­ductor potential rises to HIGH, toner will not be attracted to the
drum.

Stop

The reverse sequence takes place.
Retaining developing bias at an abnormal occurrence

Function

The developing bias will be lost if the power supply was removed
during print process. In this event, the drum potential slightly
abates and the carrier makes deposits on the drum because of
strong static power. To prevent this, the machine incorporates a
function to retain the developing bias for a certain period and
decrease the voltage gradually against possible power loss.

Basic function

Normally, the developing bias voltage is retained for a certain time
before the drum comes to a complete stop if the machine should
stop before completing the normal print cycle. The developing bias
can be added before resuming the operation after an abnormal
interruption. Therefore, carrier will not make a deposit on the drum
surface.

Process controlling

Function

The print pattern signal is converted into an invisible image by the
semiconductor laser using negative to positive (reversible) devel­oping method. Therefore, if the developing bias is added before
the drum is charged, toner is attracted onto the drum. If the devel­oping bias is not added when the drum is charged, the carrier is
attracted to the drum because of the strong electrostatic force of
the drum.

To avoid this, the process is controlled by adjusting the drum
potential and the grid potential of the Scorotron charger.

Basic function

Voltage added to the screen grid can be selected, high and low. To
make it easily understood, the figure below shows voltage transi­tion at the developer unit.
