Adjusting The Edge Emphasis Level - Canon imageRUNNER ADVANCE 6075 Series Service Manual

Adjusting the Edge Emphasis Level

The edge emphasis level of image can be adjusted in both user mode and service mode, but
the use conditions differ.
User mode
Item code Other Functions > Sharpness
Operator User
Purpose To make adjustment for each original
to be copied
Text/photo area Individual
Setting range -3 to +3 level
Default value 0 level
Setting value at power Canceled (Default value can be
OFF/ON or at reset retained.)
The following table shows the edge emphasis level by the combination of "SHARP" and
"Sharpness" settings, using the relative value when the default is 100.
Service mode "SHARP" 1

Images become smoother as values in the table become smaller, while they become sharper
as values become larger.
Note that, when "Sharpness" is the upper limit or lower limit, the relative value stays constant
regardless of the "SHARP" setting, therefore the edge emphasis effect does not change even
if the settings are changed.
Normally, adjustment is made for each copy on the Touch Panel based on the service
mode setting, but depending on the environment or paper type (coarse surface, etc.), edge
emphasis may not turn out the way the user expected.
In this case, edge emphasis level customized for the user can be set by setting the current
value of "Sharpness" as the default value.
