Figue 2-2.—Proper method of lifting a typewriter. When   a   typewriter   must   be   lifted   or moved,  it  should  be  gripped  by  its  case  and NEVER  by  the  carriage  (figure  2-2). Typewriters  should  be  covered  when  not in use. A  soft  dry  cloth  should  be  used  to  clean the  outside  of  the  typewriter. Care  should  be  taken  to  see  that  erasure crumbs  do  not  fall  inside  the  mechanism. Typewriters should be checked daily to see if  they  are  in  good  working  condition. Service  representatives  should  be  called when major work is required to fix a typewriter. MIMEOGRAPH   OPERATION AND   MAINTENANCE On  occasion,  RPs  are  called  upon  to  operate a Mimeograph. It is important that the operating manual for the model being used be studied prior to  operation  of  the  machine.  If  possible,  the  RP should  receive  instructions  on  operating  a Mimeograph from an experienced operator. This type  of  machine  is  extremely  delicate  and  a  minor mistake   in   operation   or   adjustment   could   be costly.  Detailed  information  on  preparing  and 2-4 “cutting”    stencils  is  provided  by  individual manufacturers  in  each  pack  of  stencils. Regular  maintenance  of  a  Mimeograph  is  a must.  The  RP  should  ensure  that  the  following actions  are  observed  in  regard  to  maintaining  this machine  in  good  operating  condition: The cylinder should be left with the ink pad side  “up”  when  the  Mimeograph  is  not  in  use. A  long-handled  brush  with  soft  bristles should   be   used   to   clean   lint   out   of   the Mimeograph. Feed  rolls  should  be  washed  once  a  week with  clear  warm  water.  A  clean  damp  cloth  is used  for  this  purpose. Retainer  pads  and  the  feed  pad  can  be removed  and  reversed  when  they  become  worn. The feed pad should be reversed each time it is cleaned  whether  it  shows  wear  or  not. The  impression  roller  should  be  washed regularly with a cloth dampened with a solution of mild soap and warm water. This roller should NEVER  be  immersed  in  water.  Other  cleaning fluids should NOT be used as they may damage the roller. The  ink  pad  should  be  covered  with Mimeograph  paper  and  the  backing  sheet  of  a stencil when the machine is not in use. Excess ink is absorbed by the paper and the backing sheet keeps  out  dust. A  Mimeograph  should  not  be  located  in direct sunlight or near a radiator as excess heat tends  to  cause  ink  leakage. SPIRIT  PROCESS  DUPLICATOR OPERATION   AND   MAINTENANCE Spirit process duplicator machines are used ex- tensively throughout the Navy and are normally referred  to  as  “Ditto”   machines.   NOTE:   The word  “Ditto”  is  actually  the  trade  name  of  the spirit  process  duplicator  machine  manufactured by  the  Bell  and  Howell  Company. The main advantage of the Ditto machine over a Mimeograph is its compact size which is ideal for use aboard small ships. A disadvantage is that
