Tractor
Installation
and Removal
With
this printer,
you
can use
either the tractor feed system
or
friction
feed system. For tractor feed, use
the sprocket hole paper with the
tractor already
installed.
When
you want
to use friction feed,
you can
leave
the
tractor
installed (but you'll find operation
easier
if
you remove
it).
For
friction
feed,
no need
for
paper with
holes.
Refer to
Fig. 3.
