1.MEASURE TO ALLEVIATE PROBLEMS OF FAULTY CLEANING.

2.MEASURE TO PREVENT PROBLEMS OF DISLODGING OF THE UPPER FUSING FAN.

3.MEASURE TO ALLEVIATE PROBLEMS OF FOLDED CORNERS OF THE COPY PAPER IN
THE FUSING SECTION.

4.MEASURE TO ALLEVIATE PROBLEMS OF BLURRING OF THE LEADING EDGE OF COPIES.

No. : DTE-266

1. Measure to alleviate problems of faulty cleaning.

1.Model Name: SD-3075/3076

2.General: There have been problems of the supplementary CL roller in the fusing unit warping

due to heat, causing a danger of faulting cleaning. As a measure to alleviate this
problem a change has been carried out in the finishing of the surface of the boss of the
supplementary CL roller.

(New) Phosphoric acid manganese processing CROLP1178FC31

4.Action: From 1996 September production.

2. Measure to prevent problems of dislodging of the upper fusing fan.

1.Model Name: SD-4085

2.General: There have been problems in the cleaning fan inside the chassis unit of the models

listed above. There have been cases of the fan becoming dislodged from the rotor due
to heat from the fusing unit. As a measure to alleviate this problem, a change has been
carried out in the glue used to adhere the fan. In accordance with this change a change
has also been carried out in the part code.

3.Action: From 1996 July production.

3. Measure to alleviate problems of folded corners of the copy paper in the fusing
section.

1.Model Name: SD-2075/3075/3076

2.General: There have been problems of folded corners sometimes occurring in copies caused by

the paper guide section in the fusing unit. As a measure to alleviate this problem, a
change in the shape of the paper guide section has been carried out as described in
the figure shown below.

The shaded sections (2) have
been cut away and discontinued.

4.Action: From 1996 October production.

4. Measure to alleviate problems of blurring of the leading edge of copies.

1.Model Name: SD-4085

2.General: When copy operations are carried out from the second copy paper tray with A3

(W-Letter) sized copy paper in OC mode and a magnification ratio of 64-99%,
101-144% in the models listed above, The transport clutch is turned ON at the same
time only when RRC, TBC2, TRC1 and TRC2 paper feeding operations are carried out.
As a result a sudden change in load occurs, and the revolutions of the main motor 1
(MM1) temporarily decrease, and problems of blurring sometimes occur approximately
60 mm from the leading edge of the copy paper. As a measure to alleviate this problem
a change has been carried out in the main motor to increase its power .
