2. Copier-specific Adjustments

2.1.1 To Adjust the Copy Image Quality in the Black 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 (4).

*Only the service technician must use procedures (3), (5), (6) and (7).

(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 [604] to [606], [1757] and [7807] to [7809] to make the copied text darker (sharpness level increases).

The code to use varies depending on the original mode (Text/Photo, Text or Photo). 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 05-604/605.

*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).)

After increasing the sharpness intensity, copy and check the copy image quality.

If further image quality adjustments are still necessary, use the next procedure.
