2. Copier-specific Adjustments
2.1.2 To Adjust the Copy Image Quality in the Full Color Mode
* The setting value for the Full color mode shall be applied also when the original is judged as the full color
image in the Auto color mode.
* 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 the effectiveness of the adjustment, restore the settings made in the previously used
procedure to the original ones. Then use other procedures.
* Both the service technician and the user can use procedures (1), (2) and (5).
* Only the service technician must use procedures (3), (4) and (6).
(1) Press the [BASIC] button on the Control Panel. Press the [ ] button to increase the copy density.
After increasing the copy density, copy and check the copy image quality.
With the copy density set to the maximum, if further image quality adjustments are still necessary, use the
next procedure.
(2) Press the [IMAGE] button on the Control Panel. Press the [SHARPNESS] button.
Press the [SHARP] button to increase the sharpness intensity.
After increasing the sharpness intensity, copy and check the copy image quality.
With the sharpness intensity set to the maximum, if further image quality adjustments are still necessary, the
service technician must use the following procedures.
(3) Enter adjustment mode [05]. Increase the values for codes [1737 to 1741] to strengthen the copy density of
text (or increase the sharpness intensity).
• The code to use varies depending on the original mode (Text/Photo, Text, Printed image, Photo or Map).
Adjust the value for [05] code corresponding to the original mode in which you would like to improve the
image quality and set values larger than "128" for codes 05-1737 to 1741.
Original mode [05] code Recommended value Acceptable value range Default
Text/Photo 05-1737
Text 05-1738
Printed image 05-1739
Photo 05-1740
Map 05-1741
Set a value larger than 128. 0 to 255 128
* Setting "0" provides the softest image, while setting "255" provides the sharpest image.
Changing the values for these codes will change the sharpness intensity, when the "Sharpness" indicator in
the "IMAGE" menu is set to the center. Remember that 1 step of the indicator will increase or decrease the
sharpness intensity by 25. If the sharpness intensity of the center value is changed, each step of the indicator
will be changed accordingly. (For instance, if the center value is increased by 25 (sharper), the value of each
step of the indicator will also be increased by 25 (sharper).)
