When you do not attach the release lever:
Attach the auto-cutter lock lever with the RE
(2.3); then attach the auto-cutter lock lever spring with the RE (2.3).
3. Align the auto-cutter plate assembly with the holes of the auto-cutter fixing plate.
4. Attach the auto-cutter plate assembly to the auto-cutter fixing plate. Make sure the holes for
the shafts of the auto-cutter plate assembly match the holes in the auto-cutter fixing plate.
Insert the hook end of the spring in the hole in the auto-cutter plate assembly first, and the
auto-cutter plate spring shaft and auto-cutter plate shaft in the holes of the auto-cutter fixing
plate and secure them with the RE (3). Attach the other side of the spring into the hook of the
auto-cutter fixing plate.
