1. Product features

A. Features

(1) Features

1) The employment of newly developed toner reduces the toner
consumption remarkably, realizing high fidelity pictures of
human skin, half tone, and hair. In addition, the employment of
"Auto Color" function, Sharp's unique auto recognition func­tion, reproduces documents of difficult reproduction.

2) The power consumption for FAX standby with the power OFF
is 1W or less, reducing energy expenses of nighttime and load
to the environment.

• The user authentication system by a login name, a pass-

5GTXKEG/CPWCN

word, and an e-mail address is employed to prevent against
unauthorized use of a third party and to limit the use quantity
and usable functions for each user group. In addition, the
user authentication by the optional IC card read/writer may
be used.

5) The open systems architecture (Sharp OSA) is supported
which provides application development environment accord­ing to user's needs.

6) Compact area for installation even to a space for a mono­chrome machine

The machine can be installed to a space for a monochrome
machine, the smallest space in the class of 620mm (W) x
670mm (D), helping backup of color documentations in an
office. The installation of the optional finisher (MX-FNX1)
which is stored in the center paper exit section of the machine
allows stapling and finishing such as punch holes automati­cally, improving the work efficiency.

3) Extension of the lifetime of the OPC drums together with the
frequency of maintenance realizes resource saving.

4) The unique security system inhibits unauthorized use of the
machine, preventing against leak of information.

• The electronic data are encrypted and saved in the hard

disk. When copying or printing or when sending FAX or
scanning, data are automatically erased to protect against
leak of important information.

(2) Environmental features

• Energy saving design by pre-heat mode/auto power shut-off
mode.

• Conforms to the International EnergyStar program.

• Conforms to the standards of Law on Promoting Green Purchas­ing.

• Conforms to the Europe RoHS regulations.

(The contents of lead, mercury, hexavalent chromium, cadmium,
PBB [polybrominated biphenyl], PBDE [polybrominated diphenyl
ether] are limited to the regulated level or less.)

scanned.
The scanning
speed for color is
always adopted.

Output For the output of a black-white original,

the decision to switch from color mode
to black-white mode is made when the
drum running distance shortens.
First copy (print):
If a fixed number of black-white pages
are contained in a series, switch from
color mode to black-white mode, starting
with the first page of the batch. If the
original starts with a black-white page,
the output will start in the black-white
mode.
From the second copy (print) on:
The condition is completely understood.
If there are a fixed number of black­white pages in a series, switch to the
black-white mode, starting with the first
page in the series.

Count Black-white count for the pages recognized as black-white.

Color count for the pages recognized as colored.
For N-UP, a page will be counted as a color page if there is at
least one colored page inserted upon N-UP.

1. General

Each adjustment item in the adjustment item list is associated with
a specific Job number. Perform the adjustment procedures in the
sequence of Job numbers from the smallest to the greatest.

However, there is no need to perform all the adjustment items. Per­form only the necessary adjustments according to the need.

Unnecessary adjustments can be omitted. Even in this case, how­ever, the sequence from the smallest to the greatest Job number
must be observed.

If the above precaution should be neglected, the adjustment would
not complete normally or trouble may occur.

This adjustment must be executed in the following cases:

* When the developing unit is disassembled.

* When the print image density is low.

* When there is a blur on the print image.

* When there is unevenness in the print image density.

* There is abnormally much toner dispersion.

1) Remove the developing unit from the main unit, and remove
the developing unit upper cover and the developing doctor
cover.

2) Loosen the developing doctor fixing screw.

2 Developing roller main pole position

adjustment

This adjustment must be executed in the following cases:

* When the developing unit is disassembled.

* When the print image density is low.

* When there is a blur on the print image.

* When there is unevenness in the print image density.

* There is abnormally much toner dispersion.

1) Remove the developing doctor cover, and place the develop­ing unit on a flat surface.

2) Attach a thread to a needle or a pin.

3) Hold the thread and bring the needle near the developing
roller. (Do not use a paper clip because it will not provide a cor­rect position.)

4) Mark the developing roller surface on the extension line of the
needle with the needle at 2 – 3mm from the developing roller
surface. (Never touch the needle tip with the developing roller.)

6) Remove the developing unit front cover, loosen the fixing
screw of the developing roller main pole adjustment plate, and
move the adjustment plate in the arrow direction to adjust.

Repeat procedures 3) – 6) until the developing roller main pole
position comes to the specified range.

2) Close the front cabinet.

3) Select a developing unit to be adjusted.

4) When [EXECUTE] key it pressed, it is highlighted. The devel­oping roller rotates, and the toner sensor detects toner density,
and the output value is displayed.

The above operation is executed for 3 minutes, and the aver­age value of the toner density sensor detection level is set
(saved) as the reference toner density control value.

When the reference toner density control adjustment operation
is completed, [EXECUTE] key display return, to normal from
highlight. This makes you know whether the adjustment opera­tion is completed or not.

The above operation is executed each of the lower speed
mode and the middle speed mode, and the reference toner
density control value is set for each of them.

NOTE: If the operation is interrupted within 3 minutes, the

adjustment result is not reflected (enabled).

When [EXECUTE] key is pressed during rotation, the opera­tion is stopped and [EXECUTE] key returns to the normal dis­play.

If [EE-EU], [EE-EL], or [EE-EG] is displayed, setting of the ref­erence toner density control value is not completed normally.

If the middle speed mode is adjusted after adjustment of all the
modes individually, the adjustment values of the other modes are
automatically changed. Use care for that.

Therefore, unless there may be an abnormality in the output volt­age, there is no need to check the output value.

If it must be checked that the normal voltage is outputted or if an
adjustment is required by referring to the output voltage, follow the
procedures below.

IN the case of Method 2, the right angle of paper to be used
may not be exact. Be sure to check the right angle of paper to
be used in advance.

(Method 1)

a) Measure the length of the diagonal lines from the cross

point of the outside cross pattern.

Diagonal line D

Diagonal line C

b) Calculate the difference between the measured lengths C

and D of the diagonal lines.

c) Check to insure that the difference between C and D is in

the following range.

C – D = r 0.8mm

If the difference between C and D is in the above range,
there is no need to adjust.

(Method 2)

a) Fit the three cross points of the cross patterns in a row with

the side of A3 or 11 x 8.5 paper for checking for any skew
(right angle).

Measure the right angle level by using the six cross patterns
printed in black.

There are following two methods of checking the black image
for any skew (right angle).

Method 1: Measure the length of the diagonal lines from the
cross point of the cross pattern. Check the difference in the
length of the diagonal lines for judgment of good or no good.

When the lengths of the diagonal line are C > D, shift the
adjustment screw in the direction of Y.

When the lengths of the diagonal line are C < D, shift the
adjustment screw in the direction of X.

(When Method 2 is used to check the black image for any
skew (right angle) in procedure 4)

If the image is skewed in the arrow direction of A, shift the
adjustment screw to X direction. If the image is skewed in the
arrow direction of B, shift the adjustment screw to Y direction.

7) Install the waste toner box, and close the front cabinet.

8) Execute procedures 3) – 4).

(Repeat procedures 5) – 8) until a satisfactory result is
obtained.)

9) If the adjustment result reaches the satisfactory level, tighten
the adjustment screw.

(The black image skew adjustment is completed with the
above.)

10) In the above black image skew adjustment, check the color
image skew pattern printed when completion of the adjust­ment.

11) Turn the image skew adjustment screw of the target color to
adjust.

When each adjustment screw is turned, it clicks. Turn it by
5 – 6 clicks and the check pattern is changed by 1 step (1
dot size).

When the image skew pattern on the front frame side is
skewed in the arrow direction of A (to the smaller character)
from the rear frame side, turn the adjustment screw counter­clockwise. When the image is skewed in the arrow direction of
B (to the larger character), turn the adjustment screw clock­wise.

12) Print the check pattern.

13) Check the color image skew pattern.

Repeat procedures 11) – 13) until a satisfactory result is obtained.

The image skew adjustment (LSU unit) is executed by changing
the parallelism of the LSU unit scan laser beam for the OPC drum.

Repeat procedures 3) – 4) until a satisfactory result is
obtained.

For measurement of the shift amount and the calculation of the
adjustment value, refer to the table below.

(Measurement of the shift amount and the calculation of
the adjustment value)

a) Measurement of the shift amount

* Measurement of the fine adjustment pattern

The visually highest color density section is regarded as
the center, and used as the measurement value.

(Example)

The measurement value of the figure is "7."

* Measurement of the rough adjustment pattern

Check that the color line is positioned in the plus direc­tion or in the minus direction and judge the polarity from
that.

The center black line is scaled as 0, the first line mark
as 20, the second line mark as 40, the third line mark as

60. The interval between the rough adjustment marks
corresponds to 20.

(Example)

In the case of the figure, it is between 20 – 40 of the
plus polarity, and the measurement is "20."

* The actual shift amount is the sum of the rough adjust-

ment reference shift amount and the fine adjustment
shift amount.

Shift amount (correction value) = Rough adjustment
shift amount + Fine adjustment shift amount

When calculating, be careful of the plus polarity and the
minus polarity.

(Example)

In the case of the figure, the total shift amount is 27.

Measurement value: 27 (= 20 + 7)

The shift amount from the adjustment reference position
is calculated for each of six kinds of adjustment items A
– F.

b) Adjustment value calculation

Add or subtract the shift amount calculated above to or
from the current adjustment value, and the result value is
used as the new adjustment value.

Adjustment value = Current adjustment value + Shift
amount (correction value)

(When the shift amount (correction value) is plus)

Adjustment value = Current adjustment value – Shift
amount (correction value)

(When the shift amount (correction value) is minus)

a) Measurement of the shift amount

* Measurement of the fine adjustment pattern

The visually highest color density section is regarded as
the center, and used as the measurement value of the
shift amount.

(Example)

The measurement value of the figure is "7."

* Measurement of the rough adjustment pattern

Check that the color line is positioned in the plus direc­tion or in the minus direction and judge the polarity from
that.

The center black line mark is scaled as 0, the first line
mark as 20, the second line mark as 40, the third line
mark as 60. The interval between the rough adjustment
marks corresponds to 20.

(Example)

In the case of the figure, it is between 20 – 40 of the
plus polarity, and the measurement is "20."

A: Rough adjustment pattern

B: Fine adjustment pattern

C: Adjustment range

The shift amount is calculated from the adjustment ref­erence position for each of the three adjustment items A
– C.

2) Turn the scanner drive pulley manually and shift the scanner
unit B to bring it into contact with the stopper. When the scan­ner unit B is in contact with the two stoppers on the front and
the rear frames simultaneously, the parallelism is proper.

If not, perform the following procedures.

3) Loosen the fixing screw of the pulley angle on the front frame
side of the scanner unit.

6) With the scanner unit B in contact with both stoppers, fit the
edge of the scanner unit A with the right edge of the frame, and
fix the scanner unit A with the fixing screw.

4) Adjust the position of the pulley angle on the front frame side
of the scanner unit B so that it is in contact with two stoppers
simultaneously.

5) Fix the pulley angle on the front frame side of the scanner unit
B.

If a satisfactory result is not obtained from the above proce­dures, perform the following procedures.

Loosen the fixing screw of the scanner unit drive pulley which
is not in contact.

Without moving the scanner unit drive shaft, turn the scanner
unit drive pulley manually and adjust so that the scanner unit B
is in contact with both stoppers on the front frame and the rear
frame simultaneously. (Change the relative position of the
scanner unit drive pulley and the drive shaft.) Fix the scanner
unit drive pulley fixing screw.

6) Without changing the balance of the scanner rail on the front
frame side, change the overall height.

7) Set the test chart prepared in the procedure 1) and make a
copy on A3 (11" x 17") paper. Check that the distortion in the
main scanning direction is within the specified range.

Repeat the procedures 6) and 7) until the distortion in the main
scanning direction is in the specified range.

If the distortion in the sub scanning direction cannot be deleted
with the above procedures, perform "ADJ 11D Scan image dis­tortion adjustment (Whole scanner)."

11-D Scan image distortion adjustment (Whole

scanner)

This adjustment is executed when scan image distortion cannot be
adjusted with ADJ 11A, ADJ 11B, and ADJ 11C related to the scan
image distortion adjustment.

Change the upper and lower positions of the scanner unit distortion
adjustment plate on the right edge of the scanner unit so that the
scan image distortion is minimized. By adjusting the distortion of
the whole scanner unit, the scan image distortion is adjusted.

(Note)

Before checking the coy color balance and density, be sure to exe­cute the following jobs.

* Execute the high density image correction (Process correction)

forcibly. (SIM 44-6)

* Execute the half-tone image correction forcibly. (SIM 44-26)

(Method)

Make a copy of the gray test chart (UKOG-0162FCZZ) and a copy
of the servicing color test chart (UK0G-0283FCZZ), and check that
they are proper.

a. Note for execution of the color balance and density check in the
color copy mode

To check the copy color balance and density, use the gray test
chart (UKOG-0162FCZZ) and the servicing color test chart (UK0G­0283FCZZ). Set the copy density level to "3" in the Text/Printed
Photo mode (Manual), and make a copy.

At that time, all the color balance adjustments in the user adjust­ment mode must be set to the default (center).

In addition, be sure to use the specified paper for color.

b. Note for checking the monochrome copy mode density

To check the density, use the gray chart (UKOG-0162FCZZ). Set
the copy density level to "Manual 3" in the Text/Printed Photo mode
(Manual).

In addition, all the color balance adjustments in the user adjustment
mode must be set to the default (center).

• Check with the gray test chart (UKOG-0162FCZZ)

In the copy density check with the gray test chart, check to insure
the following conditions.

NOTE: For the color (gray) balance, use the servicing color test

chart (UKOG-0283FCZZ) to check.

20-B Copy color balance adjustment (Auto

adjustment)

This adjustment is required in the following cases:

* When a consumable part (developer, OPC drum, transfer belt) is

replaced.

* When the CCD unit is replaced.

* When a U2 trouble occurs.

* When the MFP PWB is replaced.

* When the EEPROM on the MFP PWB is replaced.

* When the scanner control PWB is replaced.

* When the EEPROM on the scanner control PWB is replaced.

a. General

The color balance adjustment (auto adjustment) is used to adjust
the copy density of Cyan, Magenta, Yellow, and Black with SIM 46­24 or the user program automatically.

(When this adjustment is executed, the color balance adjustments
of all the copy modes are revised.)

There are following two modes in the auto color balance adjust­ment.

1) Auto color balance adjustment by the serviceman (SIM 46-24
is used.)

2) Auto color balance adjustment by the user (The user program
mode is used.) (The color balance target is the service target.)

The auto color balance adjustment by the user is provided to
reduce the number of service calls.

If the copy color balance is lost for some reasons, the user can
use this color balance adjustment to recover the balance.

When, however, the machine has a fatal problem or when the
machine environment is greatly changed, this function does
not work effectively.

On the other hand, the auto color balance adjustment by the
serviceman functions to recover the normal color balance
though the machine environment is greatly changed. If the
machine has a fatal problem, repair and adjust it for obtaining
the normal color balance.

To perform the adjustment, the above difference must be fully
understood.

b. Note for executing the color balance adjustment (Auto
adjustment)

1) The print engine section must have been adjusted properly.

2) The CCD gamma adjustment must have been adjusted prop­erly.

3) Be sure to use the specified paper for color.

4) Before execution of the image quality check and the image
quality adjustment, be sure to execute the following correc­tions forcibly to set the image forming section to the optimum
state.

* Execute the high density image correction (Process correc-

tion) forcibly. (SIM44-6)

* Execute the half tone image correction forcibly. (SIM 44-26)

(NOTE)

If the color balance is customized, use SIM 63-7 to register the
color balance as the service target.

If the color balance is not customized, this procedure is not
required.

If the customized color balance is registered as the service tar­get, the automatic color balance adjustment can be made in
the next color balance adjustment.

In the next color balance adjustment, select the service target
color balance in the automatic color balance adjustment mode
to make an adjustment to the similar color balance as the reg­istered color balance.

(Auto color balance adjustment target gamma setting)

a. General

When the automatic color balance adjustment is executed, a cer­tain color balance (gamma) is used as the target.

There are following three kinds of the target.

• Factory color balance (gamma) target

• Service color balance (gamma) target

• User color balance (gamma) target

In the above three, only the service color balance target can be set
to a desired level.

This adjustment is required in the following cases:

* When the copy color balance/density adjustment (manual adjust-

ment) is executed with SIM 46-21).

* When a U2 trouble occurs.

* When the MFP PWB is replaced.

* When the EEPROM on the MFP PWB is replaced.

* When the scanner control PWB is replaced.

* When the EEPROM on the scanner control PWB is replaced.

* When the user requests for customizing the color balance.

* When the service color balance target gamma is judged as

improper.

There are three kinds of the color balance target, and each
of them is specified according to the machine design. Use
SIM 63-11 to select one of them as the factory target. The
default setting (factory setting) is the color balance (DEF1)
which emphasizes color reproduction.
This target is used when the user requests to customize
the color balance to user ’s desired level. In advance, the
user’s unique color balance must be registered as the
service color balance target.
The above registration (setting) is made by the serviceman
with SIM 46-21 to adjust the color balance and with SIM
63-7 to register it.
This color balance target is used when the user executes
the color balance adjustment.
When, therefore, the service color balance target is
changed, the color balance target of the user’s color
balance adjustment is also changed. When, however, SIM
63-8 is executed, the color balance is set to the factory
color balance target set with SIM 63-11.
The default setting (factory setting) of the color balance is
same as the factory color balance target. (Emphasized on
color reproduction (DEF1))
If the user does not request for customizing the color
balance, be sure to use SIM 63-8 to set the color balance
to the factory color balance target.

Same color balance as the service color balance (gamma)
target
When the service color balance target is changed, this
color balance target is also changed accordingly.

• Service color balance target in the copy color balance adjust-

ment (SIM 45-24).

For the service color balance target, an optional color balance
can be adjusted with SIM 46-21 and registered with SIM 63-7.
When, however, SIM 63-8 is executed, the color balance is set to
the same balance as the factory color balance target set with
SIM 63-11.

• Color balance target in the user color balance adjustment

This color balance is same as the service color balance target in
the copy color balance adjustment (SIM 46-24). When, therefore,
the service color balance target is changed, this target is also
changed accordingly.

(Meaning of the service color balance target gamma data and
the purpose of registration)

This procedure must be executed only when the color balance is
customized with SIM 46-21.

If the color balance is not customized, this procedure is not
required.

After completion of the customized color balance adjustment (Man­ual) with SIM 46-21 according to the user's request, use SIM 63-7
to register the service color balance target data by use of the
printed adjustment pattern.

By this procedure, the service color balance target is revised.

It is recommendable to keep the printed adjustment pattern with
SIM 46-21. This adjustment pattern can be used to register the
same color balance target to another machine.

It is also useful to register the service color balance target data.

Do not fold it and keep it under the circumstances which protect it
from discoloration and dirt.

The service color balance target data are basically registered
immediately after the color balance adjustment (Manual) with SIM
46-21.

If a considerable time has passed after completion of the color bal­ance adjustment (Manual) with SIM 46-21, the color balance of the
adjustment pattern at the time of adjustment differs from the color
balance of the adjustment pattern printed after a considerable time.
Never use such a pattern for the adjustment.

The correctness of the service color balance target data can be
judges as follows.

Select the service color balance target with SIM 46-24 and execute
the color valance adjustment (Auto), and check the adjustment
result. When the result is unsatisfactory or abnormal, the registered
service target data for the color balance adjustment (Auto) may be
improper.

This may be caused when an improper or abnormal color balance
adjustment pattern was used to register the service color balance
target data for the color balance adjustment with SIM 63-7.

The color balance adjustment pattern used in registration was
made and printed by the color balance adjustment (Manual) with
SIM 46-21. This procedure may have been executed erroneously.

b. Setting procedure

(Setting procedure of an optional color balance (gamma) as
the service color balance target)

1) Use SIM 46-21 (Copy color balance adjustment (manual
adjustment) mode) to print two sheets of the color patch image
(adjustment pattern).

If the color balance is shifted from the standard, an adjustment
is required. If not, an adjustment is not required. When an
optional color balance is requested by the user, make an
adjustment.

(Procedures to set the service color balance target and the
color balance target for the user color balance adjustment to
the same color balance as the factory color balance target)

This procedure must not be executed when the copy color balance
was adjusted with SIM 46-21 to a unique color balance requested
by the user and it was registered as the service color balance tar­get with SIM 63-7.

* When the factory color balance target is changed with SIM 63-11,

be sure to execute this procedure.

1) Enter the SIM 63-8 mode.

3) Press [SETUP] key.

4) Set the color patch image (adjustment pattern) correctly
adjusted and printed in the copy color balance adjustment
(Manual adjustment) (SIM 46-21) (ADJ 20C) on the document
table.

The color patch image (adjustment pattern) printed with SIM
64-2 can be used instead. In this case, however, check that the
printed pattern is normal.

(When the color patch image (adjustment pattern) is printed by
SIM 64-2, set the item B (PROC ADJ) to "0 (YES)" and press
[EXECUTE] key to print.)

A color patch image (adjustment pattern) printed by another
machine can be used.

Set the pattern so that the light density side is on the left side.
Place 5 sheets of white paper on the color patch image
(adjustment pattern).

If the color balance could not be adjusted satisfactorily with
SIM 46-21 (Color balance adjustment (Manual)), do not exe­cute SIM 63-7 to register the service color balance target data.

* Execute the high density image correction (process correction)

forcibly. (SIM 44-6)

* Execute the half tone image correction forcibly. (SIM 44-26)

(Procedure)

a. When the PCL mode is supported:

Execute SIM 64-5 to print the print test pattern.

Set each set value to the default and press [EXECUTE] key. The
print test pattern is printed.

The print density must be changed gradually from the lighter level
to the darker level. The density changing direction must not be
reversed.

The density level of each color must be almost at the same level.

Patch B may not be copied.

Patch A must not be copied.

21-A Printer color balance adjustment (Auto

adjustment)

a. General

The color balance adjustment (auto adjustment) is used to adjust
the print density of each color (Cyan, Magenta, Yellow, Black) auto­matically with SIM 67-24 or the user program.

(When this adjustment is executed, the color balance adjustments
of all the print modes are revised.)

There are following two modes of the automatic color balance
adjustment.

1) Auto color balance adjustment by the serviceman) (SIM 67-24
I used.)

2) Auto color balance adjustment by the user (The user program
is used.) (The color balance target becomes the service tar­get.)

The auto color balance adjustment by the user is provided to
reduce the number of service calls.

If the print color balance is lost for some reasons, the user can
use this color balance adjustment to recover the balance.

When, however, the machine has a fatal problem or when the
machine environment is greatly changed, this function does
not work effectively.

On the other hand, the auto color balance adjustment by the
serviceman functions to recover the normal color balance
though the machine environment is greatly changed. If the
machine has a fatal problem, repair and adjust it for obtaining
the normal color balance.

To perform the adjustment, the above difference must be fully
understood.

The print density must be changed gradually from the lighter level
to the darker level. The density changing direction must not be
reversed. The density level of each color must be almost at the
same level.

b. When the PCL mode is not supported: (In the case of GDI
model)

Use SIM 67-25 to print the color balance adjustment sheet and
compare each process (CMY) black patch color balance and the
black patch to check the color balance.

This adjustment is required in the following cases.

* When the copy color balance/density adjustment is required.

Refer to the page of the ADJ print color balance/density adjust­ment.

* After execution of the copy color balance/density adjustment.

a. General

The color balance adjustment (Manual adjustment) is used to
adjust the copy density (15 points for each color) of each color
(CMYK) manually when the automatic adjustment cannot obtain
the specified result or when a fine adjustment is required or when
the user requests to change (customize) the color balance.

In this adjustment, only the patch of each color is adjusted in the
above case where the automatic adjustment cannot obtain the
specified result.

When the color balance is lost, execute the automatic color bal­ance adjustment in advance and execute this adjustment for better
efficiency.

b. Note for execution of the color balance adjustment (Manual
adjustment)

1) The copy color balance adjustment must have been completed
properly.

2) When setting the color patch image adjustment pattern on the
document table, place 5 sheets of white paper on the color
patch image adjustment pattern.

3) Be sure to use the specified paper for color.

4) Before execution of the image quality check and the image
quality adjustment, be sure to execute the following correc­tions forcibly to set the image forming section to the optimum
state.

* Execute the high density image correction (Process correc-

tion) forcibly. (SIM 44-6)

* Execute the half tone image correction forcibly. (SIM 44-26)

2) Press [EXECUTE] key. (A3 or 11" x 17" paper is automatically
selected.)

The color balance adjustment pattern is printed.

3) Check that the following specification is satisfied or the desired
color balance is obtained.

If the above specification is not satisfied, perform the following
procedures.

When the overall density is low, or when the density is high
and patch A is copied, use the arrow key to adjust all the
adjustment values of A – O to a same level collectively.

Then, adjust each patch density individually. This is an efficient
way of adjustment.

Referring to the black and gray patches, adjust so that each
process (CMY) black/gray patch color balance of A – O
approaches the black/gray patch level as far as possible.

6) Cancel SIM 67-25.

(For the machine which supports only the GDI mode, the
adjustment is completed.)

the color balance as the service target.

If the color balance is not customized, this procedure is not
required.

If the customized color balance is registered as the service tar­get, the automatic color balance adjustment can be made in
the next color balance adjustment.

In the next color balance adjustment, select the service target
color balance in the automatic color balance adjustment mode
to make an adjustment to the similar color balance as the reg­istered color balance.

(Auto color balance adjustment service color balance target
gamma setting)

a. General

When the automatic color balance adjustment is executed, a cer­tain color balance (gamma) is used as the target.

There are following three kinds of the target.

• Factory color balance (gamma) target

• Service color balance (gamma) target

• User color balance (gamma) target

In the above three, only the service color balance target can be set
to a desired level.

Kind Descriptions

A Factory color

B Service color

C User color

balance (gamma)
target

There are three kinds of the color balance target,
and each of them is specified according to the
machine design. Use SIM 67-26 to select one of
them as the factory target. The default setting
(factory setting) is the color balance (DEF1)
which emphasizes color reproduction.
This target is used when the user requests to
customize the color balance to user’s desired
level. In advance, the user’s unique color
balance must be registered as the service color
balance target.
The above registration (setting) is made by the
serviceman with SIM 67-25 to adjust the color
balance and with SIM 67-27 to register it.
This color balance target is used when the user
executes the color balance adjustment.
When, therefore, the service color balance target
is changed, the color balance target of the user’s
color balance adjustment is also changed.
When, however, SIM 67-28 is executed, the color
balance is set to the factory color balance target
set with SIM 67-26.
The default setting (factory setting) of the color
balance is same as the factory color balance
target. (Emphasized on color reproduction
(DEF1))
If the user does not request for customizing the
color balance, be sure to use SIM 67-28 to set
the color balance to the factory color balance
target.
Same color balance as the service color balance
(gamma) target
When the service color balance target is
changed, this color balance target is also
changed accordingly.

• Service color balance target in the copy color balance adjust­ment (SIM 67-28).

For the service color balance target, an optional color balance
can be adjusted with SIM 67-25 and registered with SIM 67-27.
When, however, SIM 67-28 is executed, the color balance is set
to the same balance as the factory color balance target set with
SIM 67-26.

• Color balance target in the user color balance adjustment

This color balance is same as the service color balance target in
the copy color balance adjustment (SIM 67-24). When, therefore,
the service color balance target is changed, this target is also
changed accordingly.

(Meaning of the service color balance target gamma data and
the purpose of registration)

This procedure must be executed only when the color balance is
customized with SIM 67-25.

MX-2300/2700 N/G ADJUSTMENTS 6 – 56

Factory color balance target (DEF3) =
Service color balance target/Color balance
target for the user color balance adjustment

If the color balance is not customized, this procedure is not
required.

After completion of the customized color balance adjustment (Man­ual) with SIM 67-25 according to the user's request, use SIM 67-27
to register the service color balance target data by use of the
printed adjustment pattern.

By this procedure, the service color balance target is revised.

It is recommendable to keep the printed adjustment pattern with
SIM 67-25. This adjustment pattern can be used to register the
same color balance target to another machine.

It is also useful to register the service color balance target data.

Do not fold it and keep it under the circumstances which protect it
from discoloration and dirt.

The service color balance target data are basically registered
immediately after the color balance adjustment (Manual) with SIM
67-25.
