Damaged Documents
Sheet repair is possible in many cases. A list of possible
repairs follows:
•
If a sheet is folded or crumpled, it can be flattened by
placing a flat weight on it overnight.
•
If a sheet has dark marks on it, you can erase them or
use correction tape to cover them up. If using liquid
correction fluid, be sure to allow it to dry thoroughly
before scanning as otherwise it can get on the imaging
guide and cause errors.
•
If a sheet is torn you can use tape to repair it. Be sure
to verify that the form is read correctly if taping over
marks or the timing track.
NOTE:
Tape on a sheet may generate a multiple sheet
error that will be displayed in the software.
If you are unable to repair the damaged sheet, copy the
marks from the damaged sheet onto a new one.
NOTE:
Protective sleeves cannot be scanned for data collec-
tion because of the effect the sleeve has on calibration.
