1. Regarding blank areas on copies.

1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430 (U.S.A. only)

2.General: When paper with a tendency to absorb humidity is used, a leak may occur along the
anti-static sheet while the paper is passing through the TC unit, resulting in poor copies.
This problem does not occur when using normal copy paper. To prevent this, we have
changed the placement of the TC case’s anti-static sheet for all units produced from the
middle of Oct., 1994. As shown below, we have lowered the sheet. However, as it is
difficult to change the location of the sheet for those units produced before Oct., 1994,
we have created a new set of parts, known as the AC guide unit, consisting of the AC
guide, AC guide miler and the anti-static sheet.

2. A change in the contact spring for the multi-hand-feed unit.

1.Model name: SF-MF14
SN-MF11 (U.S.A. only)

2.General: The contact spring used in the multi-hand-feed unit is difficult to attach. Therefore, a
new, improved spring with a larger inner diameter at one end will be used.

3.Action: From the beginning of mass-production

4. Concerning a strengthening of the SPF hinge.

1.Model name: SF-2214
SN-1430 (U.S.A. only)

2.General: The weight of the SPF has increased since initial production. In order to compensate
for the increased load on the SPF hinge, a strengthening process has been carried out.
