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.
CAUTION
INVISIBLE LASER RADIATION,

[5] UNPACKING AND INSTALLATION
1. Copier installation
2. Cautions on handling
Improper installation may damage the copier. Please note the following during initial installation and whenever the copier is moved.
Be careful in handling the copier as follows to maintain the performance of this copier.
Caution: If the copier is moved from a cool place to a warm place,
condensation may form inside the copier. Operation in
this condition will cause poor copy quality and malfunctions.
Leave the copier at room temperature for at least 2 hours
before use.
Do not drop the copier, subject it to shock or strike it against any
object.
Do not install your copier in areas that are:
• damp, humid, or very dusty
Do not expose the drum cartridge to direct sunlight.
Doing so will damage the surface (green portion) of the drum cartridge, causing poor print quality.
• exposed to direct sunlight
• poorly ventilated
Store spare supplies such as drum cartridges and TD cartridges in
a dark place without removing from the package before use.
If they are exposed to direct sunlight, poor print quality may result.
Do not touch the surface (green portion) of the drum cartridge.
Doing so will damage the surface of the cartridge, causing poor
print quality.
• subject to extreme temperature or humidity changes, e.g., near
an air conditioner or heater.
3. Checking packed components and
accessories
Open the carton and check if the following components and accessories are included.
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.

2. Outline of print process
Step-2: Exposure (laser beam, lens)
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.
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.

by the main charging unit. Stable potential is maintained by means
of the Scorotron charger.

Step-3: Developing (DC bias)
Step-4: Transfer
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.
The visible image on the drum surface is transferred onto the print
paper by applying a positive charge from the transfer corona to the
backside of the print paper.
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-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.
Toner is attracted over the shadowed area because of the developing bias.
AL-2051 COPY PROCESS 6 - 3
Step-7: Optical discharge (Semiconductor laser)
Start
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.
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.
When the electrical resistance is reduced, positive charges on the
aluminum layer are moved and neutralized with negative charges
on the OPC layer.
2) Developing bias (-400V) is applied when the photoconductor
potential is switched from LOW to HIGH.
Semiconductor laser
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.
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.
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.
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.
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.

Set paper on the cassette. (In the duplex mode, the manual feed
tray cannot be selected.)
C. Back copy
Document transport:
By switchback operation, the document is sent through the upper
transport roller and the PS roller to the exposure section, where the
back surface of the document is exposed.
• The document is sent to the document exit section by the lower
transport roller and the paper exit roller.
• The document is sent to the intermediate tray. (However, it is not
discharged completely.)
• The document is stopped once, and switchback operation is performed.
B. Front copy
• The document is sent through the upper transport roller and the
PS roller and the exposure section (without being exposed) to the
document exit section.
Document transport:
• The document is discharged to the document exit tray.
The document feed roller feeds the document from the paper feed
roller to the PS roller.
Paper transport:
• The document is exposed in the exposure section, and transported to the document exit section by the lower transport roller
and the paper exit roller.
• The paper is sent through the upper side of the gate section and
the duplex transport section and the PS roller, and the images on
the back surface are transferred.
• The document is transported to the paper exit tray. (However, it is
not discharged completely.)
• The paper is sent through the fusing section and discharged to
the paper exit tray.
Switchback operation is performed.
• The document is stopped once, and then switchback operation is
performed. (To the back copy)
Paper transport:
The paper is passed through the paper feed roller and the PS roller,
and the images on the front surface are transferred.
• The paper is passed through the fusing section and the lower
side of the gate section to the paper exit tray side. (However, it is
not discharged completely.)
• The paper is stopped once, and switchback operation is performed. (To the back copy)

4. Duplex adjustment
A. Adjusting the paper reverse position in
memory for duplex copying
This step adjusts the front surface printing (odd-number pages of a
document set) in the S-D mode copying and the leading edge position of an image on even-number pages in the D-S mode.
That is, it covers the adjustment of the second surface printing
mode (image loss at the front edge of an image) in which image
data is once stored in memory.
The image data is read, starting from its front end in the document
delivery direction (Reference direction of document setting in the
OC mode)and stored in memory.
This stored image data is printed starting at the printing start position, in the order of last-stored data to the first-stored data.
In other words, the front edge image loss of the image can be
adjusted by changing the document read end position.
(Adjustment procedure)
1) Preparing test chart (Draw a scale at the rear end of one side of
a sheet of A4 white paper or letter paper)
2nd printing surface where scale is printed (lower side)
B. Adjusting trailing edge void in duplex copy
mode
This is the adjustment of the first surface printing mode (rear end
void) in duplex copying.
In a duplex copying operation, the paper is delivered starting from
the rear end of the first printing surface. It is therefore necessary to
make a void area at the rear end on the first printing surface to prevent paper jam at the fusing part.
There are two adjustment modes:
1) Paper trailing edge void quantity 50-19 (TEXT)
This adjustment is made when the cassette paper size is recognized. The trailing edge void quantity can be adjusted by
changing the trailing edge image laser OFF timing.

[Adjustment procedure]
1) Set the print start position (AE mode lamp/COPY mode lamp ON) (A), the lead edge void
amount (TEXT mode lamp/PRINT mode lamp ON) (B), and the scan start position (PHOTO
mode lamp/SCAN mode lamp ON) (C) to 0, and make a copy of a scale at 100%.
2) Measure the image loss (Rmm) of the scale.
Set C = 10 x R (mm). (Example: Set to 40.)
When the value of C is increased by 10, the image loss is decreased by 1mm. (Default: 50)
3) Measure the distance (Hmm) from the paper lead edge to the image print start position.
Set A = 10 x H (mm). (Example: Set to 50.)
When the value of A is increased by 10, the image lead edge is moved to the paper lead
edge by 1mm. (Default: 50).
4) Set the lead edge void amount to
B = 50 (2.5mm). (Default: 50)
(Example)
Distance from the paper lead edge
to the image lead edge, H = 5mm
When the value of B is increased by
10, the void is extended by about
0.1mm. (For 25 or less, however, the
void amount is regarded as 0.)

When this simulation is executed, the current set correction value is displayed.
Enter the correction value and press [START] key to save the entered correction value. (Correction value range; 1 – 99, Default: 50)
For S-D mode front surface print and print of even paged in D-S mode, reverse memory copy
operation is performed from the rear edge of documents.
When, therefore, the print position adjustment of output images is required, adjust as follows:
In the reverse memory coping, when the document scan is made in the arrow direction, the output image is printed from the rear edge of scan image.
When, therefore, the print lead edge is shifted, set the reference chart so that the reference
position is on the rear edge, and use this simulation to adjust the set value so that the print lead
edge is matched.
Since printing is made from the image data most lately stored in memory to the lead edge data
from the print start position, the image lead edge adjustment is made by changing the end data
position stored in memory by the set value of this simulation.
Since it is performed by changing the scan end position, the image position adjustment is made
by changing the scan end position and the end data stored in memory.

Explanation
• Auto clear time automatically returns the copy settings to the initial settings if no keys are pressed for a preset period of time following the end of
a copy job.
• This program is used to select the period of time. Auto clear time can also
be disabled.
• This function automatically switches the machine to a low power consumption state if the set duration of time elapses without the machine
being used when the power is on. The power save indicator lights up,
however, the keys on the operation panel can be used. Normal operation
automatically resumes when a key on the operation panel is pressed, an
original is placed, a print job is received.
• Use this setting to enable or disable auto power shut-off mode.
• This function automatically switches the machine to a state that consumes
even less power than preheat mode if the set duration of time elapses
without the machine being used when the power is on. All lights except
the power save indicator go off. To resume normal operation, press the
[START] key (
). Normal operation also resumes automatically when a
print job is received or scanning is begun from a computer. While in auto
power shut-off mode, no keys (except the [START] key (
)) can be
used.
• Use this setting to select the layout pattern when two original pages are
copied onto a single sheet of paper.
• When enabled, this function offsets the position in the paper output tray of
sets of copies during copy job, and print jobs when using the printer function.
• When two-sided copying is performed, this function rotates the image on
the back of the original. This is convenient when binding the copies at the
top (tablet binding).
• This setting is used to change the copy resolution in AUTO and TEXT
mode from 600 x 300 dpi to 600 x 600 dpi (highquality mode). Scanning is
slower when high-quality mode is used.
• If the memory fills up when two-sided copying is performed, "NORMAL"
can be selected to make copying possible. However, "NORMAL" results in
a slower copying speed. Normally "HISPEED" is selected to enable fast
two-sided copying.
• Use this setting to set the margin width.
• Use this to change the proportion of machine memory used for printer
mode.
• Use this setting to select whether or not holding down a key causes
repeated input of the key. For keys that normally cause a set value to
increase when held down (for example, holding down the [
] key (
)
or [
] key (
)), this program can be used to have the set value not
change when the key is held down.
• Use this setting to select how long a key must be pressed for the input to
be accepted. By selecting a longer time, you can prevent settings from
being changed by the accidental pressing of a key.

Explanation
• This sets the volume of beep signals.
• Use this to sound a beep when a base setting is selected.
• This mode reduces toner usage by about 10% when copying. Toner save
mode is effective when the exposure mode is AUTO or TEXT.
• This is used to adjust the exposure level.
• The automatic exposure level can be adjusted separately for the document glass and the RSPF.
• The factory default setting for the exposure level is "center".
This is used to set the language used in the display.
18 Languages can be selected.
This is used to return all settings to the factory default settings.
Use this setting to enable or disable sort auto select mode.
• You can set the operation that takes place if the [START] key (
) is
pressed when the RSPF is not completely closed.
• Set the allowed paper sizes for copying from the bypass tray. When "B5"
is selected, a copy of a letter size original will only be printed up to invoice
size.
• Select whether copying is only allowed when the polygon motor is rotating, or also when the polygon motor is stopped.
• Set the temperature of the fusing unit when the bypass tray is used. Normally "PLAIN PAPER" should be selected.
• Set the contrast of the display.

Explanation
When this function is enabled, printing in printer mode will automatically
continue using a different size of paper if the specified size of paper runs out
in all trays. This feature does not function in copy mode.
This sets the USB 2.0 data transfer speed. To obtain the fastest speed when
using the USB 2.0 connector, first verify that your computer meets the
system requirements (operating system and driver), and then use this
program to change the USB 2.0 mode to "Hi-Speed". Note that the setting
should not be changed while running a TWAIN driver.
This is selectable when the optional paper tray is installed.
(This is not shown when the optional tray is not installed.)
This is to select whether or not to make the network connection by TCP/IP
protocol effective.
This is to select whether or not to apply to DHCP network connection.
This is to set IP address, Subnetmask and Default Gateway from the
machine. This can also be used to check the machine’s IP ADDRESS when
"IP ADDRESS" is selected. When the program number 4 "ENABLE DHCP"
is "ON" and the machine is under DHCP environment, the IP address on the
display is shown with " " at the tail end.
* The scanning speed increases when the USB 2.0 mode is set to "HI-SPEED", however, the printing speed does not increase considerably.
