Notes on slip paper
The slip paper must be flat, without curls or wrinkles, especially
at the top edges. Otherwise, the paper may rub against the ribbon
and become dirty.
There must be no glue on the bottom edge. Choose slip paper
carefully since paper feeding and insertion are affected by gluing
conditions (such as glue quality, method, and length) and glue
location (see the illustration below). Be especially careful when
the slip paper is wide and has glue on the left edge, since it may
not feed in a straight line.
