To Adjust The Copy Image Quality In The Full Color Mode - Toshiba e-Studio6506AC Imaging Manual

2.7.2 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 (3).
* Only the service technician must use procedure (2).
(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 copy image quality.
With the background density set to the minimum, if the images seen through the back of the page are still
copied, the service technician must use the next procedure.
(2) Select [05 ADJUSTMENT MODE]. Change the values for the following codes below to adjust the density
level of the background.
Adjustment
Full color / Auto color
(when judged as color)
Full color
* Set the value in increments of approximately 10, while checking the copy image until the optimum value is
obtained.
* The value for the code corresponding to the original mode (Text/Photo, Text, or Printed image) will affect
the copy image quality in the Full color mode and the Auto color mode.
<Note> "Making the highlighted area more visible (or increasing the background density)" and
"eliminating the background color (or decreasing the background density)" are mutually
contradictory. If the density of the background color is decreased, the highlighted area may
become less visible.
After adjusting the background density, copy and check the copy image quality.
If further image quality adjustments are still necessary, use the next procedure.
