COPIER : SF-2014
1. TROUBLE SHOOTING UNCLEAR COPY IMAGES WHICH OCCUR WHILE USING THE SPF.
2. CHANGE IN IC USED IN THE MAIN PWB TO IMPROVE PRODUCTIVITY.
3. CHANGE IN DV LOWER GUIDE PLATE DUE TO IMPROPER PRESSURE WELDING OF THE
DEVELOPING UNIT.
4. CHANGE IN THE LENGTH OF THE LEAD WIRE OF THE PS CLUTCH IN THE SPF UNIT TO
IMPROVE PRODUCTIVITY.
No. : SP-1931
1. Trouble shooting unclear copy images which occur while using the SPF.
1.Model name: SF-2214
SN-1430 (only for machines bound for the USA)
2.General: The copy image is sometimes affected by the revolving load of the transport roller
caused by contact between the roller and the SPF harness in the SPF unit. To alleviate
this problem, the measures described below have been carried out.
3.Description: Previously, the harness was held taught by a wire band, preventing it from coming in
contact with the transport roller. As a better method of separating the harness from the
roller, the length of the harness wires has been changed so that the harness can be
re-routed to avoid contact with the roller, as shown in the figure below.

2. Change in IC used in the main PWB to improve productivity.
1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430 (only for machines bound for the USA)
2.General: The IC used in the main PWB [IC 107] has been changed to increase productivity. This
change has no affect on the shape or function of the machine or its parts.
3.Action: ∗ Japanese production: From the start of 1995 August production.
Chinese (SOCC) production: From the start of 1995 September production.
French (SMF) production: Running change after stock is used up.
3. Change in DV lower guide plate due to improper pressure welding of the developing
unit.
1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430 (only for machines bound for the USA)
2.General: There is a possibility of improper pressure welding of the developing unit being caused
by the DV guide plate bending upwards, which pushes up the developing unit, resulting
in improper pressure welding.
3.Description: As shown in the figure to the right, the
angle of the DV guide plate where it is
attached by the attachment screws has
been changed to prevent the plate from
bending upwards.

4. Change in the length of the lead wire of the PS clutch in the SPF unit to improve
productivity.
1.Model name: SF-2214
SN-1430 (only for machines bound for the USA)
2.General: The lead wire of the PS clutch used in the SPF unit is longer than that used in other
machines, and was previously shortened by binding it with a wire band, so that it could
be used in the same way as with the other machines. To improve productivity, however,
the PS clutch has been changed.
3.Description:
4.Action: ∗ Japanese production: From 1995 mid-October production.
Chinese (SOCC) production: From 1995 mid-November production.
French (SMF) production: From 1995 mid-December production.
