kind is set to 1, the background delete function of the docu-
ment kind is enabled.
To reproduce the document colors directly, set this setting to
OFF (0).
After entering the set value, press [OK] key to save the entered
value to the memory.
Set item H (TH_MAX_MONO):
Used to set the density level at which the background delete
function is enabled for monochrome background documents.
Set to the range of 0 – 16.
To delete the background of light-density documents: Increase
the set value.
To delete the background of dark-density documents:
Decrease the set value.
After entering the set value, press [OK] key to save the set
value to the memory.
Set item I (TH_MAX_COLOR):
Used to set the density level at which the background delete
function is enabled for color background documents.

Decrease the set value.
After entering the set value, press [OK] key to save the set
value to the memory.
Set item J (SW_NEWS):
Used to set Enable/Disable of the newspaper (monochrome)
background delete function.
It is not affected by the set item H.
For newspapers of color background, this setting is invalid.
After entering the set value, press [OK] key to save the set
value to the memory.
Used to set Enable/Disable of the background delete function

function is enabled for monochrome background documents.
Set to the range of 0 – 16.
To delete the background of light-density documents: Increase
the set value.
To delete the background of dark-density documents:
Decrease the set value.
After entering the set value, press [OK] key to save the set
value to the memory.
Set item I (TH_MAX_COLOR):
Used to set the density level at which the background delete
function is enabled for color background documents.
Set to the range of 0 – 16.
To delete the background of light-density documents: Increase
the set value.
To delete the background of dark-density documents:
Decrease the set value.
After entering the set value, press [OK] key to save the set
value to the memory.
Set item J (SW_NEWS):
Used to set Enable/Disable of the newspaper (monochrome)
background delete function.
It is not affected by the set item H.
For newspapers of color background, this setting is invalid.
After entering the set value, press [OK] key to save the set
value to the memory.
Set item A (TH_MODE_SCR):
Used to set the mesh are level at which the background delete
function is enabled for printed documents with mesh images.
To delete background of documents with much mesh area:
Increase the set value.
To delete background of documents with less mesh area:
Decrease the set value.
Select TH_MODE_SCR, enter the set value, and press [SET]
key to save the entered value to the memory.
Used to set the mesh are level at which the background delete
function is enabled for printed documents with mesh images.
To delete background of documents with much mesh area:
Increase the set value.
To delete background of documents with less mesh area:
Decrease the set value.
Select TH_MODE_SCR, enter the set value, and press [SET]
key to save the entered value to the memory.
(NOTE)
Enable/Disable of the background delete operation is determined
by AND condition of A (SW MODE1) – G (SW MODE7), H (TH_
MAX_MONO), I (TH_MAX_COLOR), and A (TH_MODE_SCR).
For newspapers documents, however, it is determined by the set
item J (SW_NEWS) only.
Except for the above set items, do not change the setting in the
market. Set them to the default values.

When the machine is used with some adjustment values changed
from the default values, this adjustment is required in the following
cases.
* When a U2 trouble occurs.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.
* When the user requests for the adjustment.
This setting is used to set the recognition level of a color image in a
document.
The actual ACS operation is executed according to the combination
of the judgment reference value in the color auto mode set by the
device and this setting.
When a monochrome document cannot be judged as a mono-
chrome document or when a color document cannot be judged as a
color document, change this setting. This setting is applied to the
color auto copy mode.
