¾Lines on the rear images
To correct streaks on the rear side images, you must follow the same procedure, as
previously noted, for the front imaging guide. The rear imaging guide is located in the
base of the transport. Before re-installing the rear imaging guide, clean the cover glass
that is located between the two lamps in the base of the transport. Just as with the
imaging guides, use a slightly-dried Staticide wipe to wipe the entire width of the imaging
guide.
¾Lines on front or rear black and white images (changing binarization settings.)
If you find that you need to frequently clean your scanner to prevent streaks in your
black and white images then, consider modifying your ‘conversion quality’ or binarization
settings. If you are using the ‘Best (iThresholding)’ setting (your scanning software may
use a different name) then you may find that decreasing your Contrast value will greatly
reduce the frequency of lines in your images.
¾Large black borders on images or images look too small in the viewer.
The i1800 Series Scanner is normally setup to ‘Automatically Detect and Straighten’
documents as they are being scanned. Your software may call this feature ‘Auto-crop
and De-skew’ or some similar name, but the function is the same. This feature will allow
the scanner to create straight images of only the page that was scanned.
