Microfiche scanners for microfiche conversion projects can become a big headache for many organizations. Although there are simple scanning equipment that can solve small tasks, for real scanning production you need a microfiche scanner that can take care of any and all issues that you will encounter with COM fiche, 16mm jacketed fiche, step-and-repeat fiche, rewritable fiche, 35mm strips, etc).
Good microfiche scanning equipment (NextStar, Sunrise, Mekel, Wicks & Wilson, etc.) will offer an experienced operator many tools to work with. It takes a person a long time of training and operating this expensive scanning equipment to be able to make good use of an advanced microfiche scanner. You may get by with just knowing some things, but like with everything else, you are not going to get the best results or good results until you really know what you are doing.
