CONTROL OF FAST-COPY MACHINES A   problem   which   requires   the   attention   of everyone  in  your  office  is  the  control  and  use  of fast-copy machines. Increased availability of these machines    has    created    security    problems    and increased operating costs. These machines permit quick, easy reproduction of uncontrolled classified material. Latent impressions are left on reproduction   equipment.   This   creates   excessive waste material that can contribute to compromise of classified information. Some misuses and abuses that contribute to high operating cost are: Using a copier instead of making carbons Copying blank forms or publications Making more copies than are needed Using a copier for items that should have been copied by the print shop Controls   should   be   established   to   prevent unnecessary costs and prevent security abuses CALCULATORS Calculators add, subtract, multiply, and divide. Most  models  in  use  by  the  Navy  are  capable  of performing   a   variety   of   complex   mathematical operations but do not produce a paper tape of the results.    A    substantial    amount    of    training    is required  to  operate  a  calculator  with  proficiency. Simple   multiplication   and   division   that   an   SK would be required to perform can be learned in a few minutes. MICROFICHE Many  publications  used  by  the  Navy  supply system are in the form of microfiche. They require the use of a microfiche reader. These  readers  are easy to use and do not require specialized training. Figure 3-2 shows typical fiche data fields. PUBLICATIONS The  publications  you  will  use  can  be  divided into     two types: procedural and technical. Operations    are    governed    by    law.    Procedural manuals   have   been   developed   to   assist   Navy personnel    in    performing    their    jobs.    Efficient procedures  have  been  developed  that  save  time and limit mistakes. They also make communications  between  commands  clearer   and easier to understand. When you transfer from one ship to another, this uniformity makes it easier to transition into the new assignment. Technical publications are necessary because of the  wide  range  of  material  required  to  keep  the Navy operating. You will use technical publications primarily to identify material. The  publications  needed  by  ships  and  stations vary, but those described below  are used  by most supply departments afloat.
