not the pattern on each... the pattern across all of them together... put
the first one down and then the next and so on head to tail... it is
possible that the drum is larger around than the paper is long... make sure
you get them in the proper order and oriented right... it is likely to be
just one line on the drum... you can tell this if the lines are all the
same distance apart across the sheets... there's no way i can do an ascii
drawing to show what i'm talking about ;(

i didn't say take it apart... it may be possible to rotate the gear while
sliding the ruler in the same way that the gear in a cdrom drive drives the
door open on its toothed rail...
