[1] PRODUCT OUTLINE

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.

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 (When option installed.).

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

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.

(2) Environmental features

5GTXKEG/CPWCN

• 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.)

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 645mm (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.

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.

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.)

If the distance is not within the above range, adjust the devel­oping roller main pole position in the following procedures.

Note for use of a clearance gauge

• Use a non-polarity gauge.

• Do not insert the gauge diagonally.

• The gauge must pass with its own weight. (It will free-fall if you
release your hand from it.)

• The advisable point of measurement is the MIN point of the MG
roller oscillation.

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).

5) Use SIM24-5 to clear the developer counter.

6) Use SIM44-27 to clear the half-tone correction data.

NOTE:

1) When replacing developer, always replace all the three colors
of Yellow, Magenta, and Cyan.

If only one color is replaced, color balance may be adversely
affected. Black developer can be replaced individually.

2) After replacement of developer or the photoconductor, be sure
to execute SIM44-27 to clear the half-tone correction data.

If the above procedure is neglected, the half-tone correction
may not be performed correctly.

When the adjustment value (specified value) of the middle speed
mode is set, the adjustment values of the other modes are auto­matically set according to the middle speed mode setting in a cer­tain relationship.

To adjust all the modes individually, first adjust the middle speed
mode, and then adjust the other mode.

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.

1) Remove the main unit rear cover.

4) Check the printed black image for any skew (right angle).

j

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.

Method 2: Use the right angle sides of A3 or 11 x 8.5 paper for
judgment of good or no good.

NOTE:

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

b) Measure the shortest distance between the cross pattern

on the extended line of the vertical line and the paper side.

If the above distance is 0.5mm or less, there is no need to

adjust.

If not, execute the following procedures.

5) Open the front cabinet, and remove the waste toner box.

6) Loosen the LSU (writing) unit fixing screws (2 pcs.) and shift
the skew adjustment screw in the arrow direction to adjust the
LSU (writing) unit skew.

(When Method 1 is used to check the black image for any
skew (right angle) in procedure 4)

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)

R

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.

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)

MX3500N ADJUSTMENTS 6 – 17

(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

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

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

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.

Default

• 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

(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.

Before checking the copy color balance and the density, be sure to
execute the following procedures in advance.

* 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-

To increase the density, increase the adjustment value. To
decrease the density, decrease the adjustment value.

Repeat procedures of 2) – 5) until the condition of 3) is satis­fied.

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.)

7) Use SIM 64-5 to print the print test pattern.

NOTE: Only for the machine which support the PCL mode.
(For the machine which supports only the GDI mode, this pro­cedure cannot be used.)

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

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.

8) Use SIM 44-26 to execute the half tone image correction (forc­ible execution).

Enter the SIM 44-26 mode and press [EXECUTE] key.

[EXECUTE] key is highlighted and the operation is started.

• The patch density is identical between patches or not reversed.

• The patch density is changed gradually.

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.

When, however, the color balance is adjusted according to a
request from the user, there is no need to set to the standard
color balance stated above.

3)PatchCorDofeachofY,C,M,

2) Patch A of each of Y, M,
C, and BK are not copied.

It takes several minutes to complete the operation. After com­pletion of the operation, "COMPLETE" is displayed.
