The following description provides you with a brief overview of some basic microfilming techniques and principles. The descriptions are aimed at the novice operator; however, even if you are a more experienced operator you may find it helpful to review this information.

The microfilm used in the scanner must meet the following specifications:

Width — 16 mm, unperforated.

Types — silver microfilms can be used to produce originals or duplicate reels. However, duplicates from silver originals are more commonly made using diazo microfilm (which provides direct duplicates of the original), or vesicular/thermal microfilm (which provides reverse polarity duplicates). Any microfilm selected must have a clear base. Tinted-base microfilms cannot be used with the scanner. However, if tinted-base originals are duplicated on clear base microfilms, the duplicate copies can be used.

Film Leader — M-type film leader must be clear; black leader cannot be used.

Thickness — 2.5 to 5.0 mils.

NOTE: Thermal films less than 4 mils thick can stretch during processing and become narrower than 16 mm, which can result in unreliable performance.
