14.2.8 Remove blank pages (0=deactivated)
This function makes most sense whenever you want to scan your papers recto and verso although only a part of the stack (one third, for example) has any information on the reverse side. Enter the conditions for the removal of blank pages in the following way:
20.56
The first is a threshold value for the amount of black on the page expressed in one-tenth of a percent. '20', for example, means that any page whose surface area is less than twenty-tenths of a percent (or 0.02 percent) black will be deleted. (The margin mentioned above is not counted in the calculation of this.)
The second value stands for the margin in pixels that is not taken into consideration for the calculation of the proportion of black (as against white) on the page.
Please note that the two values need to be separated by a full stop. We recommend that you take a figure between 10 and 40 for the first value. The higher the first value the more black a page may contain. The lower the first value, the higher the chance that pages with only a little black information are integrated into the archive. The second value must be '8' or a multiple of it such as '40', '48', etc.
0 means that there are no empty pages to delete.
