1. Change carried out in the binding method of the AC harness line.

1.Model Name: AR-280/285/335 (only for machines bound for the 200 V series market destinations)

2.General: The AC harness line is rather thick, and is therefore very difficult to bind using a wire

saddle. The creates the possibility of the AC harness line coming into contact with the
fusing gear. As a measure to alleviate this problem, the addition of a wire band has
been carried out.

Only for machines bound for the 200 series
market destinations.
The AC harness and the main harness are
bound between the fusing drawer connector and
the fusing gear.
(Care should be exercised to insure that contact
is not made with either the lead wire or the
fusing gear.)
