No. : SP-1900

1. Prevention of dual side mis-copies during full-face half-tone copy operations.

1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430

2.General: The volume of light from the copy lamp in the copy check operations during the
production process is sometimes slightly less at the right and left edges of the copy
paper than in the center. As a result, when half-tone copy operations are carried out,
both sides of the paper (right and left) are sometimes a little darker than the center of
the paper. To improve production efficiency, the measures described below have been
instituted.

3.Description: Side reflectors have been installed in the lamp unit to increase the amount of light
received by both sides of the copy paper.

Side reflectors.

Because the side reflectors are not
necessary in the market, they have not
been offered as standardized service parts.

4.Action: Japanese production:

SF-2214 (all locations): From 1994 mid-December production.
SF-2014/2114 (bound for SEEG): From 1995 mid-January production.

SF-2014/2114 (except for SEEG): From 1995 mid-May production.
Chinese(SOCC)production : From the start of mass production.
French(SMF)production : From 1994 November production.

2. Measures to improve exposure light adjustment operations.

1.Model name: SF-2114/ 2214
SN-1420/1430

2.General: There is no margin for adjustments for the photographic mode exposure adjustments
during the copy check operations of the production line. T o remedy this situation the
following measures have been taken.

3.Description: The tightening of the lens has been changed as an improvement measure, from the
previous F8 setting to an F9 setting.

4.Action: Japanese production: From 1995 mid-July production.
Chinese(SOCC)production: From 1995 mid-April production.
French(SMF)production: From 1995 mid-August production.

3. Measures to prevent dislodging of the dark box cover.

1.Model name: SF-2014
Z-800 (USA only)

2.General: The cover of the dark box sometimes became dislodged during transport of the
machine itself. To alleviate this problem the following measures were taken.

3.Description: (1) Step screws were added as stoppers

as shown in the figure to the right, to
prevent the cover of the dark box from
moving.

Step screw used as a stopper.

(2) Until the measure described in (2) above

was implemented, the screw designated by
the arrow in the figure to the left was changed
and used as a stopper. The change described
above, however, the original screw has been
replaced.
LX-BZ0512FCZZ → LX-BZ0353FCZZ

(All three screws have become the same).

Note: The parts code listed in the parts guide is “XBPSD40P08KS0", but as

described above, the actual parts code is different, and the parts code listed in
the parts guide is an error. A correction of this parts code is requested.
