2. Copier-specific Adjustments
2.7.1 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 procedure (1) and (2).
* Only the service technician must use procedures (3) to (5).
(1)
Press [IMAGE] on the Control Panel. Press [BACKGROUND ADJUSTMENT].
Press [LIGHT] 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.
(2) Press [BASIC] on the Control Panel. Press [ ] to decrease the copy density.
* Move the copy density indicator to the “ ” side for 1 or 2 steps. The images seen through the back of the page
will no longer be copied. But remember that text will also be lightly copied, depending on the type of original.
After decreasing the copy density, copy and check the copy image quality.
With the copy density set to the minimum, if the images seen through the back of the page are still copied, or if
you would like to prevent this problem without changing the copy density of text, use the next procedure.
(3) Select [05 ADJUSTMENT MODE]. Change the values for codes [7100] to [7102], [7105] and [7106]
adjust the density level of the background.

* The smaller the setting value, the lighter the background becomes, while the larger the setting value, the
darker the background becomes.
Adjust the value and determine the optimal value while checking the copies by considering that the
setting value "25" for the [05] code corresponds to one step in the background adjustment on the control
panel.
After adjusting the background density, copy and check the copy image quality.
If further image quality adjustments are still necessary, use the next procedure.
