A system for microfilming documents that employs microprocessor control to insure fault-free operation. The aspects of operation; such as document present, size of document, size of photographic mask, the exposure parameter, and system 'ready', must meet necessary criteria, or the microprocessor will halt operations and present a human-readable response as to the cause. Substitutional tables for supporting documents are available, to relate to the characteristics of the document. Simultaneous conflicting commands are executed sequentially according to a priority sequence.

Microfilming system

A programmable printer for printing identifying indicia upon a moving document prior to microfilming the document. The printer is adjustably stationarily mounted above a document transport table. Alpha-numeric characters are selectively formed and briefly depressed to print the desired indicia upon successively presented documents while the same are moving. A programmable microcomputer forms the characters from predetermined data and applies each in correspondence with the motion of the document at an interval of time when microfilming is not occurring.
