1. Counter measures for black streaking during reduced copies
1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430 (USA only)
2.General: Rib cuts have been carried out on the BL holder to alleviate problems of black streaks
which had been occurring during reduced copy operations of the SPF mounted machines.
3.Description:
The rib cuts mentioned above were carried out by hand from the start of mass
production to 1994 October production, of the SF-2214, SN-1430 models, which are
SPF mounted machines. From 1994 November production, the rib cuts have been
carried out on all models in the metal molding stage.
4.Action: From the start of 1994 November production
2. Prevention of double feeding
1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430 (USA only)
Rib cuts carried out at these locations.
2.General: When the pressure springs of the separator roller in the bottom frame were attached
diagonally to the boss on the base plate side, double feeds were occasionally caused
by increases in the pressure of the spring. The changes described below have been
carried out to alleviate this problem.

3. Counter measures for barker roller return malfunctioning in the paper feeding unit
1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430 (USA only)
2.General: To prevent the barker roller in the 250 cassette unit from malfunctioning (the roller
sometimes becomes jammed and remains in the lowered position instead of raising
back up, in some cases preventing the cassette from being withdrawn), the spring load
of roller release arm spring 250 had been changed by altering the shape of the already
installed springs, but now the springs are being changed in the metal moulding stage as
a permanent measure.

4.Action: Temporary action: From the start of mass production to 1994 mid-October production
Permanent action: From 1994 mid October production
4. Prevention of skipping (Abnormal noise) of the PS connection gear in the feeding unit
1.Model name: SF-2014/2114/2214, Z-800
SN-1420/1430 (USA only)
2.General: The connection arm occasionally became loose and the one way clutch gear slipped
due to idling torque when the transport roller in the feeding unit rotated during
production, causing abnormal noise. To alleviate this problem, the measures described
below were carried out.
3.Description: The spring load of the paper guide front spring was increased to prevent the gear from
slipping.
Diameter: φ 0.4 → φ 0.55
Spring load: 18 mm — 104 g → 18 mm — 350 g

5. Prevention of transfer misalignment during copy operations
1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430 (USA only)
2.General: A change in shape has been carried out on the TC case unit to prevent transfer
misalignment problems during copy operations.
