Read Explanation:
The Four Typewriter Scales
Marginal Scale (or Paper Table Scale):
This scale is located on the Paper Table (the flat surface behind the platen).
It helps the typist center the paper and align the edges with the margins.
Carriage Scale (or Paper Bail Scale):
This scale is located near the Paper Bail (the bar with small rollers that holds the paper against the platen/cylinder).
It is used to judge the horizontal position of the type element (where the next character will print) in relation to the margins.
Front Scale (or Line Space Adjusting Scale):
This scale is typically located at the front base of the carriage near the platen.
It is used to control the vertical line spacing (single, double, or triple spacing).
Line Finder Scale (or Alignment Scale / Paper Guide Scale):
This is the scale or index (pointer) usually fixed near the printing point on the machine frame.
It indicates the exact position on the paper where the type bar will strike, which is critical for making small adjustments or aligning with pre-printed lines.
