Braillo 600 SR, User Manual

Page: 47 / 119

Please see the figure on the previous page.
The two shafts, one at the top and one at the bottom, are rotating synchronized. On each shaft there
are eccentrics that are pushing the beams and papershoes up and down. This movement is used both
to hold the paper and to make the dots. A row of dots is printed for each revolution of the shafts. The
shafts must rotate three times to form a complete row of characters.
Please see figure below:
First revolution
Second revolution
Third revolution
To be able to print interpoint (where both sides of paper are printed simultaneously), the back page is
offset a little to the right and a little down to fit in between the dots on the front page.
