Excellent quality photocopy of the original 1992 3M 900/955 Series Overhead Projectors Service Manual.

This 26 page illustrated manual is printed on double sided 8-1/2"x11" heavy weight paper and plastic comb bound to lay flat on the workbench. It contains sections on the introduction, operation and maintenance, troubleshooting, adjustments, electrical diagrams and disassembly / reassembly. This manual does not have the parts breakdown, which is a separate publication.
