2.General: Var ious changes and additions have been carried out on parts in the models listed
above, and are hereby reported. Please refer to the parts lists for changes in the parts
names and parts codes.

1. Changes in the lengths of each harness have been carried out to improve

operationability.

Effective time: From 1995 June production. (Running change after all present units

in stock have been used.

2. A change in the shape of the connection duct has been carried out. In accordance

with this change a mylar sheet which had been attached to prevent loose connections
(Reported in T echnical Reports no. SP-1874 ) has become unnecessary and has been
discontinued.

Added built-up section

Effective time: Running change from 1995 July production.

3. As a counter measure for copy image blurring and black streaks, a spacer had been

added to prevent the SPF glass retainer from moving or becoming loose (Reported in
Technical Report no. SP-1874.), but a change in the shape of the SPF glass retainer
has made the spacer and the mylar unnecessary, and they have both been
discontinued.

Effective time: From 1995 mid-April production.

4. A fusing blade plate and scraper sheet has been attached from the start of mass

production to prevent the upper heat roller in the fusing unit from becoming dirty with
paper dust. In reality, however, assembly and installment of these two parts on
machines already out on the market is extremely difficult, and therefore full y ass emble d
“fusing scraper units” are instead offered as service parts.
