Purpose of the Imaging Manual
The Imaging Manual is intended for customers using the Toshiba e-STUDIO350/450 and
e-STUDIO200L/230/230L/280/280S with a variety of specific needs and inquiries for high image quality, such as:
x How to obtain a clearer copy image
x How to maintain the current image quality
x How to make the text look sharper on the copy
The Toshiba MFPs are factory-configured to provide image quality settings that satisfy the majority of customers.
However, these settings may not be necessarily optimal for all specific needs from customers. Proper image
quality adjustments can satisfy such needs. Most of the adjustments described in this manual must be performed
by a service technician, but a few of them can also be performed by the customer.
It is strongly recommended that this manual be fully utilized by not only the service technician, but also the sales
representative, who also has opportunities of obtaining customer feedback on the image quality. This manual
helps the sales representative to study and comprehend what kind of customer needs for the image quality can be
satisfied, to make a proposal to the customer for improving image quality, and to communicate the customers
needs with ease to the service technician. In addition, this manual is expected to facilitate the marketing of the
Toshiba MFPs to prospective customers that have specific demand for image quality and the expansion of sales.
The adjustments described in this manual are all based on the needs of actual customers. Meeting their specific
needs will increase their satisfaction.
Please remember to read "Cautions after the completion of the adjustment," which you must pay close attention
to, after the completion of the adjustment.
Precautions in Servicing
• For adjustments to be performed by the service technician, the cautions mentioned in the Service Manual must
be stringently followed. The adjustments must be performed by a qualified service technician who has
completed the service training course.
• The default values mentioned in this manual may be different from the actual ones, due to the timing of
shipping (firmware version). But note that the values recommended and acceptable value range mentioned in
this manual remain the same.

Before the adjustment
After the adjustment
The black area looks slightly blurred on the copy.
The black area looks clear on the copy.
‰ Explanation
When an original containing a large-sized logo or a graphic image is copied or printed out, the solid black area
sometimes looks slightly blurred on the copy. Adjust the toner density, transfer transformer DC output and laser
power output, in order to fix the sufficient amount of toner on the solid black area and obtain a clearer image output.
‰ Procedures
* The service technician must perform the adjustment in accordance with the procedures below.
1.1
e-STUDIO350/450, e-STUDIO200L/230/230L/280/280S
1. General Adjustments – Copying, Printing and e-Filing (Output from Box)
(1) Enter setting mode [08]. Change the value for code [414] to increase the toner density in the developer
material.
For e-STUDIO350/450
• Set "1," "2," "3," and "4" for code 08-414 in order and increase the toner density gradually, while visually
checking a change in the image quality.
Value for 08-414
Toner density
0
Default
1
Approximately 0.5 wt% higher than the default value
2
Approximately 1.0 wt% higher than the default value
3
Approximately 1.5 wt% higher than the default value
4
Approximately 2.0 wt% higher than the default value
For e-STUDIO200L/230/230L/280/280S
• Set "1," "2," and "3" for code 08-414 in order and increase the toner density gradually, while visually
checking a change in the image quality.
Value for 08-414
Toner density
0
Default
1
Approximately 0.3 wt% higher than the default value
2
Approximately 0.6 wt% higher than the default value
3
Approximately 0.9 wt% higher than the default value
<Notes> • The effect of the toner density adjustment cannot be determined or a change in the image quality
cannot be identified, until approximately 50 copies are made after the completion of the
adjustment. The effect of the adjustment can also be determined by the frequency of toner
supply. When the toner supply operation is performed frequently after the adjustment, you can
identify a gradual increase in toner density.
• Increasing the toner density may possibly cause an increase in the amount of toner consumed,
scattering of the toner, fogged images, diminished photo images or gradations (less accurate
reproduction of halftones), extremely dark images (decreased resolving power), and loss of the
life in the consumables. Therefore, carefully perform the adjustment, while checking the copy
or print image.
• An image quality problem may occur when the copier is used for a while after the toner density
is adjusted. Do not change the toner density value from the default unless necessary.
After increasing the toner density, print and check the image quality.
If further image quality adjustments are still necessary, use the next procedure.

1.1
1. General Adjustments – Copying, Printing and e-Filing (Output from Box)
(2) Change the value for adjustment mode [05] or setting mode [08] to increase the toner transfer efficiency.
For e-STUDIO350/450
Enter adjustment mode [05]. Increase the value for code [221] to increase the toner transfer efficiency.
• Before changing the value for code 05-221, remove the developer unit from the copier. Use steps (a) to (e)
to make the setting.
(a) Change the value for code 08-203to "1."
(b)Remove the developer unit from the copier.
(c)Check the value set for code 05-221.
* The value set for code 05-221 varies on a machine-by-machine basis, because it is adjusted prior
to shipment, in accordance with the characteristics of each machine.
(d) Increase the value for code 05-221 by 15.
* For instance, if the current value is "114," change it to "129."
(e) Reinstall the developer unit to the copier.
(f) Reset the value for code 08-203 to "0."
<Notes> • Setting "1" for code 08-203 allows the copier to be placed in line adjustment mode. While the
copier is in line adjustment mode, the high voltage output life control is disabled. Therefore, if
the copier is continuously used in line adjustment mode, this may cause significant reduction in
the life of consumables and many kinds of image quality problems. Therefore, once you have
changed the value for code 08-203 as described above, remember to reset it to "0."
• Increasing the transfer charger output (toner transfer efficiency) may possibly cause blotched
images and diminished photo images or gradations (less accurate reproduction of halftones).
Therefore, carefully perform the adjustment, while checking the copy or print image.
• As an image quality problem may occur, do not change the transfer charger output value from
the default unless necessary.
For e-STUDIO200L/230/230L/280/280S
Enter setting mode [08]. Change the value for codes [830], [868], and [869] to increase the toner transfer
efficiency.
* The following three setting codes are available for transfer charger output depending on the paper transfer
position: leading edge, center, and trailing edge. Change the value for all three setting codes equally to
perform the adjustment.
• To adjust the transfer charger output at the leading edge of the paper:
Increase the current 08-868 value by 15. (The default value is "128.")
• To adjust the transfer charger output at the center of the paper:
Increase the current 08-830 value by 15. (The default value is "128.")
• To adjust the transfer charger output at the trailing edge of the paper:
Increase the current 08-869 value by 15. (The default value is "128.")

Change the value for code 08-876 to "143." (The default value is "128.")
To adjust the print image quality
Change the value for code 08-872 to "143." (The default value is "128.")
<Notes> • Increasing the intensity of the laser may possibly cause diminished photo images or gradations
(less accurate reproduction of halftones) and extremely dark images (decreased resolving power).
Therefore, carefully perform the adjustment, while checking the copy or print image.
• As an image quality problem may occur, do not change the intensity value of the laser from the
default unless necessary.
‰ Cautions after the completion of the adjustment
The adjustment may possibly cause an increase in the amount of toner consumed, scattering of the toner, fogged
images, blotched images, diminished photo images or gradations (less accurate reproduction of halftones),
extremely dark images (decreased resolving power), and loss of the life in the consumables. Therefore, carefully
perform the adjustment, while checking the copy or print image.
‰ Remarks
The effect of the adjustment may vary, depending on the usage pattern of the consumables, such as the developer
material and drum, and the operating environment of the copier.

1.3 To Achieve the Image Quality Most Suitable for Paper Used
(To prevent the image printed on the back of the paper from being blotched in duplex mode)
Before the adjustment
The image, which is printed on the back of the
paper, may be blotched in duplex mode,
depending on the type of paper used.
After the adjustment
The image quality most suitable for the
paper used is obtained.
‰ Explanation
When an original containing halftones, such as a photo or gradations, is copied or printed out in duplex mode,
the halftone image on the back of the paper (or the printed side that is delivered facing downwards in duplex
mode) may sometimes be blotched, depending on the type of paper used. Adjust the transfer charger output
value in duplex mode, in order to prevent the image from being blotched and obtain a clear image quality.
* This adjustment will be effective, only if the image printed on the back of the paper is blotched in duplex mode.
Remember that it will not affect the quality of the image printed on the front of the paper (or the printed side in
simplex mode or the side that is delivered facing upwards in duplex mode).
‰ Procedure
* The adjustment is performed by the service technician only.
(1) Change the value for setting mode [08] to adjust the transfer charger output, when the image is printed on
the back of the paper. (Decrease the transfer charger output value, in order to prevent the image from being
blotched and finely reproduce halftones.)
For e-STUDIO350/450
Enter setting mode [08]. Change the value for code [492] to adjust the transfer charger bias output value,
when the image is printed on the back of the paper.
• Change the value for code 08-492 to "91." (The default value is "106.")
* Code 08-492 is intended to adjust the transfer charger bias output value, when the image is printed on the
back of the paper. Remember that using this code will not affect the quality of the image printed on the front
of the paper (or the printed side in simplex mode or the side that is delivered facing upwards in duplex mode).

1. General Adjustments – Copying, Printing and e-Filing (Output from Box)
For e-STUDIO200L/230/230L/280/280S
Enter setting mode [08]. Change the value for code [491], [492], and [493] to adjust the transfer charger
output, when the image is printed on the back of the paper.
* The following three setting codes are available for transfer charger output depending on the paper transfer
position: leading edge, center, and trailing edge. Change the value for all three setting codes equally to
perform the adjustment.
• To adjust the transfer charger output at the leading edge of the paper when the image is printed on the back of the paper:
Decrease the current 08-491 value by 20. (The default value is "149.")
• To adjust the transfer charger output value at the center of the paper when the image is printed on the back of the paper:
Decrease the current 08-492 value by 20. (The default value is "139.")
• To adjust the transfer charger output value at the trailing edge of the paper when the image is printed on the back of the paper:
Decrease the current 08-493 value by 20. (The default value is "128.")
* Codes 08-491, 08-492, and 08-493 are intended to adjust the transfer charger output, when the image is
printed on the back of the paper. Remember that using this code will not affect the quality of the image
printed on the front of the paper (or the printed side in simplex mode or the side that is delivered facing
upwards in duplex mode).
<Hint>
• "Dither" is selected as the gradation processing method by default in Photo mode. Dither is
intended to reproduce finer and smoother halftones. If a double-sided copy/print is made in
Photo mode, the image on the back of the paper may not be blotched, unlike the case where it is
made in Text/Photo or Text mode (default gradation processing method: error diffusion).
• The image on the back of the paper may be blotched, depending on the direction of the fibers of
paper used. Therefore, changing the paper orientation may sometimes prevent the image from
being blotched. For instance, when a double-sided copy/print is made on A4/LT-sized paper in
portrait orientation, the image on the back of the paper may be blotched. But if it is made on
A4/LT-sized paper in landscape orientation (A4-R/LT-R), the image may no longer be blotched.
• After adjusting the transfer charger bias output value, print and check the image quality.
‰ Cautions after the completion of the adjustment
The adjustment may slightly decrease the darkness of a solid filled area printed on the back of the paper.
Therefore, carefully perform the adjustment, while checking the copy or print image.
‰ Remarks
• Enter the value mentioned in the procedures. Otherwise, it may produce little effect on the image quality. In
addition, it may cause a loss in copier performance, including degradation in the image quality and reduction in
the life of the consumables.
• The effect of the adjustment may vary, depending on the usage pattern of the consumables, such as the
developer material and drum, and the operating environment of the copier.
• The desired image quality may not be obtained, depending on the type of paper used. In this case, use the
recommended paper and then print or adjust the image quality.

1.4 To Fix the Sufficient Amount of Toner on a Photo or Gradational Image
(To improve the fusibility of the toner and reduce the frequency of the copier
pausing during the copying/printing operation)
Particularly when this type of gradational
image is copied or printed on thick paper with
the higher density, the toner may easily peel
off (on rare occasion).
‰ Explanation
When an original containing halftones, such as a photo or gradations is copied or printed out, the toner may
easily peel off (on rare occasion), depending on the type of paper used, operating conditions or environment of
the copier. Change the fuser unit control method, in order to make the toner fully fixed on any type of paper and
to prevent the copier from frequently pausing during its copying or printing.
‰ Procedures
* The procedure varies depending on the model of the copier. To adjust the e-STUDIO350/450, refer to "1.4.1
To Adjust the e-STUDIO350/450" and to adjust the e-STUDIO200L/230/230L/280/280S, refer to "1.4.2 To

1.4.2 To Adjust the e-STUDIO200L/230/230L280/280S
* You can start with any of the procedures, but an adjustment should be prioritized, if necessary.
* The service technician must perform the adjustment in accordance with the procedures below.
* Procedure (1) is to change the pre-running interval during the warm-up time and will be effective if all types of
paper, including plain paper, are used.
* Procedure (2) is to change the pre-running interval prior to printing and will be effective if plain paper mode is
used at low temperature or if thick paper mode, TRANSPARENCY (OHP FILM) mode, or ENVELOPE mode
is used.
(1) Enter setting mode [08]. Change the value for code [423] or [517] to specify the pre-running interval during
the warm-up time at normal or low temperature.

2.5 To Clearly Copy at the Trailing Edge of the Paper in Duplex Copying
(To adjust the bottom margin on the back of the page in duplex copying)
In duplex mode, the bottom margin on the
back of the page is narrow. This makes the
image at the trailing edge of the paper become
less clear.
The bottom margin on the back of the page is
properly increased. This makes the image at
the trailing edge of the paper become clearer.
Paper feeding direction
After the adjustment
Paper feeding direction
Before the adjustment
‰ Explanation
In duplex copying, the bottom margin (margin at the trailing edge of the paper) on the back of the paper (or
printed side delivered facing downwards) may be narrower than on the front (or printed side delivered facing
upwards) in simplex or duplex copying, depending on the paper size and how much paper is moistened. This
results in the faint image at the trailing edge on the back of the paper. Adjust the bottom margin, in order to
clearly copy at the trailing edge on the back of the paper.
* This adjustment will have an effect only on the image printed on the back of the paper in duplex copying.
Remember that it will not affect the image printed in simplex copying, or the one printed on the front of the
paper in duplex copying.
‰ Procedures
* The service technician must perform the adjustment in accordance with the procedures below.
(1) With the platen cover or RADF opened, make a double-sided copy. (Copy a solid black image.)
• Checking the copy image, determine how much the bottom margin should be increased.
* Select the best paper size for duplex copying, if necessary. It is recommended to use the paper, which is
most frequently used for duplex copying.
* When making a double-sided copy of the solid black image, place blank paper on the original glass,
allowing the solid black image to be copied only at the trailing edge on the back of the paper, for toner

* Set "0" for the subcode. Setting "1" for the subcode allows you to adjust the right margin on the back in
duplex copying, but it is not necessary here. Therefore, never change the value for subcode 1.
• After the adjustment, make a double-sided copy again, with the platen cover or RADF opened and check
the image at the trailing edge on the back of the paper. If further image quality adjustments are still
necessary, repeat step (2).
<Hint>
If the user is concerned regarding the image quality at the trailing edge on the back of the paper,
set a slightly wider bottom margin (3 to 4 mm). If not, it is recommended to set it to 2 to 3 mm.

2.6 To Adjust Reproducibility to Uses in Photo Mode
(To attach importance to halftone reproducibility, text reproducibility or reduction in moiré)
Dither-processed
Error diffusion-processed
A copy is made to reproduce halftones (photo
area) more clearly.
A copy is made to reproduce text distinctly
and minimize moiré.
‰ Explanation
The following two gradation processing methods for photo mode (reproducing halftones with binary data) are
available: "Dither" attaching greater importance to reproducibility of photos and gradations and "Error diffusion
processing" attaching greater importance to text reproducibility and reduction in moiré. By selecting either of
these methods effectively, the image quality in photo mode can be adjusted in accordance with the users’
preferences and the uses of the copy image.
‰ Procedure
* The adjustment is performed by the service technician only.
(1) Enter setting mode [08]. Change the value for code [502] to select the gradation processing method in
accordance with the users’ preferences and the uses of the copy image.

2.7 To Program Frequently Used Copy Settings
(To use Custom mode)
‰ Explanation
For the e-STUDIO350/450 and the e-STUDIO200L/230/230L/280/280S, three original mode options are
available by default: Text/Photo, Text and Photo. In addition, "Custom" mode is available, allowing more
specific image quality adjustments, in order to satisfy the users’ needs. It is strongly recommended to use
Custom mode to program frequently used copy settings for a particular copy job. Custom mode is the most
suitable for the user, who often makes special copies or who is not satisfied with the image quality provided by
the default original mode options.
* The following three Custom mode options are available: Text/Photo-based, Text-based and Photo-based.
Select one. Custom mode can be used, independent of the default original mode options. Therefore, adjusting
the value for Custom mode will not affect the default original mode settings (Text/Photo, Text and Photo).
‰ Procedures
* Perform the adjustment in accordance with the procedures below.
* Procedures (1) and (2) are used by the service technician only.
* Procedure (3) is used by the service technician, and by the user.
(1) Enter setting mode [08]. Change the value for code [508] to select one of the default custom mode options.
• Select the custom mode option, which is based on the default original mode option most suitable for the
image quality the user desires. Remember that the item, which can be adjusted, varies, depending on the
selected custom mode option. (Refer to "Remarks" in the table below.)

* Setting any value from "1" to "3" for code 08-508 will enable Custom mode and allow the user to select it
as one of the original mode options on the Control Panel. Immediately after Custom mode is enabled, the
default values for the default original mode option, which Custom mode is based on, will be applied. For
instance, if "2" is set for code 08-508, Custom mode 2 will be enabled. All the factory-shipped values
(default values) for Text mode will be applied in Custom mode 2 without being changed.
After selecting the Custom mode option, use the next procedure.

* Correlation of image density level value among subcode numbers should be that the higher the subcode
number is, the higher the image density level value is. If the image density level value for a lower subcode
number is greater than that for a higher subcode number, an image quality problem may occur.
Ex.: When the image density level for 672-0, 672-1, 672-2, 672-3, and 672-4 is assumed to be "A0",
"A1", "A2", "A3", and "A4" respectively, they should have the following correlation:
A0 ≤ A1 ≤ A2 ≤ A3 ≤ A4
After adjusting the image density level, print and check the image quality.
‰ Cautions after the completion of the adjustment
Increasing the image density level may possibly cause diminished photo images or gradations (less accurate
reproduction of halftones), an increase in the amount of toner consumed, and extremely dark images (decreased
resolving power). Therefore, carefully perform the adjustment, while checking the printout.
‰ Remarks
• Enter the value recommended in the procedure for adjustment.
• The effect of the adjustment may vary, depending on the usage pattern of the consumables, such as the
developer material and drum, and the operating environment of the copier.

Ex.: When the image density level for 672-0, 672-1, 672-2, 672-3, and 672-4 is assumed to be "A0",
"A1", "A2", "A3", and "A4" respectively, they should have the following correlation:
A0 ≤ A1 ≤ A2 ≤ A3 ≤ A4
After adjusting the image density level, print and check the print image quality.

3. Printer-specific Adjustments
‰ Cautions after the completion of the adjustment
The adjustment may possibly cause graininess or variations in the print density on the halftones or text areas,
degradation in photo or gradational images (less accurate reproduction of halftones), extremely light images
(decreased resolving power), and lower image density in the solid filled area. Therefore, carefully perform the
adjustment, while checking the printout.
‰ Remarks
• Enter the value recommended in the procedure for adjustment.
• The effect of the adjustment may vary, depending on the usage pattern of the consumables, such as the
developer material and drum, and the operating environment of the copier.
• The image density in toner save mode can also be adjusted. For further information regarding the adjustment
procedures, refer to 3.4 To Adjust the Image Density in Toner Save Mode.

Default printing.
Printing is performed, while the toner is being
saved.
‰ Explanation
Enable toner save mode on the printer driver or adjust the laser power output and image density level in order to
reduce the amount of toner used to print the output, for instance, if a large number of copies have to be printed,
or if the image density is too high.
‰ Procedures
* The procedure varies depending on whether to perform printing in toner save mode, to adjust the laser power
output, or to adjust the image density level. To decrease the print density on a user-by-user or temporary basis (to
decrease the print density for a particular job), refer to "3.3.1 To Perform Printing in Toner Save Mode." To
constantly decrease the image density for all jobs of all users, instead of using toner save mode, refer to "3.3.2 To
Adjust the Laser Power Output" or "3.3.3 To Adjust the Image Density Level." Note that "3.3.2 To Adjust the
Laser Power Output" applies only to the e-STUDIO350/450 (not to the STUDIO200L/230/230L/280/280S.)

(To change the density in Copy to Box)
Before the adjustment
After the adjustment
The black-and-white image is stored in Photo
mode. When it is opened on an application,
text looks very light.
If it is stored in Text or Text/Photo mode, text
will look darker and clearer.
‰ Explanation
When a black-and-white original containing both photo images and text is copied and stored in the e-Filing box
(Copy to Box), text may be stored with the low-density, depending on the type of original, because Photo mode is
intended to improve the reproducibility of halftones. Change the original mode option and adjust the scan density,
in order to obtain a darker and clearer image, when the image stored in the e-Filing box is to be imported into an
application on a client PC.
* Please remember that the e-Filing functions are available only on the Windows platform, but not on the
Macintosh or UNIX platform.
‰ Procedures
* All the adjustments are performed by the service technician, and by the user.

4.2 To Store the Original Attaching Importance to Gradation
Reproducibility of Printed Image
(To change gradation of the image scanned and stored by Scan to Box)
Before the adjustment
After the adjustment
Depending on the type of original or resolution,
the gradation is lost when the image is printed
after being scanned and stored in the e-Filing
box.
The gradation is not lost even when the image
is printed after being scanned and stored in the
e-Filing box
‰ Explanation
When an original containing images such as photo images is scanned and stored in the e-Filing box (Scan to
Box) and the scanned image data is printed directly from the e-Filing box, the gradation of the printed image
may be lower than that of the original.
Scan to Box scans image data and stores it in the e-Filing box attaching importance to "image quality displayed
on the computer monitor" and "image quality scanned at 200 dpi (default) and printed." As a result, depending
on the type of original or scanning resolution, a printed image may be blurred due to high image density of
halftones (loss of gradation.) To scan and store the original attaching greater importance to "gradation
reproducibility of printed image" than "image quality displayed on the computer monitor", adjust the image
processing conditions for scanning (range correction.)
* This adjustment will be effective only when the original is scanned and stored into the e-Filing box (Scan to
Box), and ineffective when copied or printed and stored into the e-Filing box (Copy to Box or Print to Box.)
* This adjustment will be effective only when an original is scanned in "Text/Photo" mode or "Photo", and
ineffective when scanned in "Text" mode.
* This adjustment should be performed before an original is scanned and stored in the e-Filing box. Note that the
image quality of the images already stored in the e-Filing box cannot be adjusted.

* The above file sizes are just for your reference.
* The above file sizes are just for your reference.
If the original is constantly scanned at the
default compression rate, the file size will
become larger than required.
If the original is scanned at a reasonable
compression rate, depending on the purpose of
the scanned-in image, the file size will be
successfully reduced.
‰ Explanation
If an original is scanned at the default settings, a proper image will be obtained for general purposes. But the file
size may become larger than required. The file size of the scanned-in image significantly varies, depending on
the selected resolution or original mode. If an appropriate resolution and an original mode option are selected in
accordance with the purpose of the original, the image quality will be maintained, while the file size is being
reduced. Change the resolution and original mode, in order to minimize the file size of the scanned-in image.
‰ Procedures
* You can start with any of the procedures. But it is recommended to perform the procedures in order, as listed
below. You can use one procedure in conjunction with another. But if this changes the image quality more
than required or loses effectiveness of the adjustment, restore the settings made in the previously used
procedure to the original. Then perform the next procedure.
* All the adjustments are performed by the service technician, and by the user.

5. Scanning-specific Adjustments
(1) When scanning the original, press the [EDIT] button on the Control Panel. Select a lower resolution option
in the "RESOLUTION" option.
* In the "RESOLUTION" option, "200 (dpi)" is selected by default. Select a lower resolution option (150
dpi) to reduce the file size.
After changing the resolution, scan the original and check the scanned-in image quality.
If further image quality adjustments are still necessary, use the next procedure.
(2) When scanning the original, press the [EDIT] button on the Control Panel. In the "ORIGINAL MODE"
option, select [TEXT].
* Perform this adjustment, only if the original containing no photo images is scanned or if degradation in the
photo image quality is acceptable.
* This adjustment will be effective, only if [TEXT/PHOTO] or [PHOTO] is initially selected from among
the original mode options.
After changing original mode, scan the original and check the scanned-in image quality.
If further image quality adjustments are still necessary, use the next procedure.
‰ Cautions after the completion of the adjustment
• The table below shows you the correlation between the adjustment and file size. (The ratio of the file size may
vary, depending on the type of original. Therefore, use the table below just for your reference.)
• Correlation between a resolution and file size (procedure (1))
* The file size in a resolution of 200 dpi is 100%.

5. Scanning-specific Adjustments
(1) Enter adjustment mode [05]. Increase the value for code [865/866/867] to increase the sharpness intensity.
• The code to use varies, according to original mode (Text, Text/Photo or Photo). Adjust the value for the
[05] code corresponding to original mode for which you would like to improve the image quality and
change the value set in ten place.
(Change the value in ten place to "3" or more in Text mode, or "4" or more in Text/Photo mode and Photo
mode. The sharpness intensity will be increased, compared with the one provided by default.)
* Set value (Ex.: The sharpness intensity in Text/Photo mode (code 05-865) is "6.")

* With "0" set in ten place, the following sharpness intensity is provided as the default value in each original
mode:
• "0" set in Text mode:
The image becomes sharper than the one obtained when "2" is set, but
softer than the one obtained when "3" is set.
• "0" set in Text/Photo mode:
The image becomes sharper than the one obtained when "3" is set, but
softer than the one obtained when "4" is set.
• "0" set in Photo mode:
The image becomes sharper than the one obtained when "3" is set, but
softer than the one obtained when "4" is set.
‰ Cautions after the completion of the adjustment
The adjustment may possibly cause moiré. In addition, when text and thin lines in a colored background are
scanned, the background around the text or line may be eliminated. Therefore, carefully perform the adjustment,
while checking the scanned-in image.
