Operating  Instructions—C-30B  Camera

Installing the  Roll  Film

1.  To  load  the  roll  film   pack,  open  the  camera  back  by 

releasing  the  latch  lever,  and  install  the  roll  film   by 

following  the  detailed  instructions  contained  in  the 
film   box.

2.  Close  the  back  cover and  hold  it shut.  Swing the  latch 

lever  all  the  way  towards  the  bottom   of  the  camera 
back  to  ensure  that  both  sides  of  the  back  cover w ill 
latch,  then  swing  the  latch  lever  to  the  locked 
Position  (towards  the  top  o f the  camera  back). There 
should  now  be  a short tab o f paper extending  beyond 
the  cutter bar of the  camera  back.

3.  Install  the  dark  slide  in  the  camera  back  to  prevent 

exposing the  first frame.

4.  Hold  the  camera  back  and  lift  the  cutter  bar  by 

raising  up  on  the  plastic edge. Once the  cutter bar has 
been  lifted,  it  w ill  remain  in  the  up  (unlocked) 
Position  until  it  is pushed  down.

5.  Pull  the  film   leader  out  of  the  camera  back  until  it 

comes  to  a  firm   stop.  About  15  inches  of  the  film  

leader  must  be  pulled  out  before  it  w ill  stop  in  the 
proper  Position  for the first exposure.

6.  Lock  the  cutter  bar w ith  a gentle  downward  pressure. 

A fter  it  has  latched,  tear  the  film   leader  o ff  and 
discard  it.

7.  The  camera  back  is  ready for the first picture.  Mount 

the  camera  back  on  the  camera  main  frame and  make 

proper  shutter and  lens opening settings.

8.  Remove  the  dark  slide  before  taking  a  picture.  The 

number  of  exposures  remaining  on  the  roll  is 
indicated  on  the  film   tab  under  the  cutter  bar.

Advancing  and  Developing the  Roll  Film

A fter  a  picture  is  shot,  advance  and  develop  each  ex­

posure  as follows:

1.  Throw  the  red  release  switch  in  either  direction  to 

release the film .  If you  should  throw   it accidentally  at 
any  other  time,  d on't  w orry—no  harm  is  done.

2.  Open  the  cutter  bar  by  lifting  the  plastic  edge  and 

take  a  firm   grip  on  the  film  tab.  With  a  single  motion 

pull  the  film   tab  straight  out about seven  inches.  Pull 
it  about  as hard  and  rapidly  as you  might  pull  down  a 

window  shade;  not  hard  enough  to  pull  the shade o ff 
the roll  (or the film   o ff the spool), but not slowly  and 

hesitantly.  Remember,  the  film   w ill  stop  auto- 
matically.

NOTE

I f  the  film   tab  w ill n o t p u ll easily,  throw  the red re­
lease switch again.

3.  Press  down  and  latch  the  cutter  bar.  Tear  o ff  and 

discard  the excess paper.

4.  Wait the  recommended  development time.  Follow the 

directions  in  the  instruction  sheet  for  development 
times  under  various  conditions.  It  is  important  that 
you  check  the  instruction  sheet  for  exact  develop­

ment  time.  This  time  varies  for  different  types  of 
film ,  and  even  the  development  time  for  a  particular 
film   may  change.

5.  When the development time  is up, slide  back the  latch 

on  the  print  door  and  open  the  door.  L ift  the  print 
out  carefully,  starting  with  the  cutout.  D on't  let  the 

print fall  back on  the  damp  negative.

W A R N I N G

Many  developing  Solutions  contain  a  caustic  sub-

 

stance  which  may  cause  Chemical  burns.  i f   you

 

accidentally get  the  solution on yourskin,  wipe it  o ff

 

immediately and  wash  the  area thoroughly as soon as

 

possible.  Be  extremely  carefui  to  keep  the  solution

 

away from  the eyes and mouth.

6.  Close and  relatch  the  print door.

7.  A pply  the  print  coater  along  the  entire  length  of the 

print,  including  edges,  borders,  and  corners.  Use  six 

to  eight  firm ,  overlapping strokes.  For the  last two or 
three  pictures  in  each  roll,  press the  coater down  hard 
against  the  top  end  of  the  p rint  (not the  image)  for a 

moment  to  release  extra  liquid; then  spread  the  liquid 
smoothly across the  print.
