SHARP S207 Technical Report

Date: Jun. 5, 1997

COPIER : SF-2050

MEASURE TO COMPLY W ITH EMI (ELECTRICAL NOISE) ST ANDARDS.

1.Model Name: SF-2050 (only for machines bound for the Taiwan market)

2.General: EMI (electrical noise) standards have been put in effect in Taiwan as of 1997 January.

In accordance with this market development, the changes described below have been
carried out.

No. : S-207

1) A change in the high voltage transistor has been carried out, and the high voltage
transistor for the 200 V series is now being used.

2) The main harness R with the ferrite core attached used for machines bound for the
U.S.A. market has been changed to a main harness R with a new ferrite core attached
to it.

3) The AC PWB has been changed to one with a new capacitor added to it. In
accordance with this change the AC PWB has been changed to an AC PWB with a
ferrite core attached to it.

4) A new AC cord unit has been established for machines bound for the Taiwan market.

5) The addition of a noise filter 2 unit has been carried out in compliance with the new
standards. The noise filter 2 unit is attached by use of a binding band.

6) The addition of a CL coil unit has been carried out in compliance with the new
standards. The CL coil unit is attached by use of a binding band.

6) CL Coil unit.
The CL coil unit is connected between the 3 pin connector (copy lamp line) which is
connected to the optical unit. Afterward, a snap band is used to secure it to the optical
unit.

Care should be exercised to insure that the lead wire of
the 3 pin connector which is connected to the optical unit
does not come in contact with the mirror motor when
securing it to the main harness.
