GRAFLEX - Graflex Grafmatic 23 Service

Comprehensive service and parts manual for the Graflex Grafmatic 23 automatic sheet film holder, published January 1965 by Graflex, a division of General Precision Equipment. This workshop documentation covers every aspect of maintaining and repairing the six-sheet film magazine used in professional cut-film photography. The manual opens with a clear overview of the Grafmatic 23's design and compatibility with Graphic camera backs, including guidance on optional spacer washers for smooth insertion. The operation section is thorough—it walks through the two fundamental handling movements (PUSH and PULL) that control the film drawer and compartment mechanism, with particular attention to pressure limits on the focusing panel and correct use of the exposure counter dial, details that separate proper operation from premature wear. A dedicated troubleshooting guide presents a comprehensive fault table mapping symptoms to their root causes and specific remedies, addressing the full range of issues likely to occur in field use: drawer binding, light leaks creeping in around seals, counter dial failures, and spring breakage. The manual then provides step-by-step disassembly and reassembly procedures with important handling cautions to prevent component damage during service work. Technical specifications and materials data ensure technicians understand what they're working with. A detailed labeled technical illustration identifying all 33 component parts serves as a visual reference for accurate identification and correct parts ordering. Essential reading for anyone responsible for maintaining Graflex film backs in a studio or field setting.
