2. Copier-specific Adjustments
2.6.2 To Adjust the Copy Image Quality in the Full 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) and (4).
* Only the service technician must use procedures (2) and (3).
(1) Press the [AUTO] button on the Control Panel to select the automatic density adjustment.
(2) Press the [IMAGE] button on the Control Panel. Press the [BACKGROUND ADJUSTMENT] button.
Press the [LIGHT] button to decrease the background density.
After decreasing the background density, copy and check the image quality.
With the background density set to the minimum, if further image quality adjustments are still necessary, the
service technician must use the next procedure.
(3) Enter the adjustment mode [05]. Change the values for the following codes below to adjust the density level
of the background.
