Seiko Instruments LTP F Series User Manual

When determining the layout of paper holder, note the following:

z

  When you use a paper roll, set the holder so that the paper is straight in relation with the paper

inlet without any horizontal shifting, and the center axis of the paper roll is parallel with the
printer.

z

  Paper supply load to the printer should be 0.49N (50gf).

The dimensions of alignment for the mechanical unit and the platen unit are shown in Figure 6-3 for a
situation when the platen unit has been mounted to the outer case, and the unit has been opened and
closed.

Design the mounting position of the revolving point on the platen unit for the outer case so that it is
contained within the dimension tolerance shown in Figure 6-3.
In some construction cases of the outer case, the mechanical unit and platen unit may be able to be
matched even if the mounting position etc. of the platen unit is outside the dimension tolerance shown
in Figure 6-3. Make sure that excessive stress is not applied to the outer case and/or platen unit in
said situation.

An incorrect mounting position of the revolving point on the platen unit may cause an alignment failure
of the mechanical unit and/or the platen unit, leading to printing problems. The installation of an
exclusive autocutter may cause bad cutting or paper jams.
