Systems and methods of ensuring the erasure of transient documents are disclosed. The systems and methods include an imaging device that sends a transient document with a pre-printed image into an erase cycle to attempt to remove the image from the document. After the erase cycle, a scanner scans the transient document and converts the transient document into a digital image. A processor compares bit depths of individual bits of the digital image to a bit depth threshold. Depending on the comparison and a number of completed erase cycles, the transient document enters an additional erase cycle, completes as sufficiently erased, or is rejected as not sufficiently erased.
