Punch hole removal *

Punch hole removal will detect any smudges or shadows caused by punch holes and then remove them. Works with monochrome images only.

Please note: this function only has an effect on monochrome images, it has no effect on grayscale or color images.
The Ignore monochrome pages, Ignore gray scale pages and Ignore color pages options are therefore not changeable for this function.

Filter:

The following filters determine which pages this function is applied to.

Processing on page

Perform this function on ...

Both sides

Front pages

Rear pages

The Front pages and Rear pages options only work with scanners that offer a corresponding page-distinction feature and also transmit this information via the TWAIN driver.

Ignore monochrome pages, Ignore gray scale pages, Ignore color pages

Specifically applies to multistream mode. If any of these three filters are set to On, punch hole removal is turned off for the respective page types. Please note that grayscale and color pages are permanently turned off, by default, since this function will only perform on black & white images.

Ignore blank pages

Turns this function off, for all blank pages.

Ignore first document page

Causes this function to skip the first page of every document (which usually is the page triggering document separation).

Ignore cover pages

Turns this function off, for cover pages.

Output:

Switched on

Switches this module on or off. Turning this function off will preserve all settings, for later use (as opposed to removing the function). Useful when developing or troubleshooting project templates.
