No. : SP-2012

NOTIFICA T ION OF CHANGES AND ADDI TI ONS OF PART S.

1.Model name: SF-2116/ 2118/1016/1018

2.General: Additions of parts have been made, and changes have been carried out on some of the

parts in the models listed above, and are hereby reported.

(1) Cases have occurred whereby the manual actuator attached to the lower portion of

the right cabinet was dropped, and a change in the shape of both end portions of the
actuator has been carried out as a measure to prevent this problem from reoccurring.

This change is effective from 1995 mid-October production.

(2) Changes have been carried out in the PID PWB used in the upper frame, and in the

DPPD circuit board of the paper feeding unit. Resistors had been installed on the back
side of the circuit boards in the in order to improve the performance of the paper
sensor, but these resistors have been changed for even more improvement. A change
in the parts codes of the circuit boards has also been carried out in accordance with this
action.

This change is effective from the start of 1996 February production.

(3) The shape of the fusing roller in the lower frame unit has been changed from a

straight shape to an inverted crown shape to alleviate problems of wrinkling during
black beta and half-tone copy operations.
Note: When using the fusing roller after the change has been carried out it is necessary
to adjust the height of the paper guide in the fusing unit. Paper guide spacers and a
page of explanations have been added to the user’s kit (consumable items).

<When Using the Fusion Roller>
When using fusing roller N
(NROLR1058FCZZ) it is necessary to
attach spacers (PSPAG0691FCZZ) to
the P/G. Your cooperation concerning
this matter is requested.
Note: Action has already been carried
out in the fusing UN for ➀ and ➁
below, and the addition of spacers is
therefore not necessary.

∗ Japanese production

This change is effective from the start of 1995 August production.

French production (SMF)

This change is effective from 1995 mid-August production.

(4) Additions of parts have been made, and changes in some of the parts have been

carried out in order to alleviate the occurrence of F2 trouble and improve operations
efficiency .
Note: Changes have also been carried out in the printing content of the silk screening in
accordance with the changes described above.

∗ Japanese production

Running change will be effective from the start of 1995 December production.

Chinese production (SOCC)

This change is effective from the start of 1996 February production.

(5) In order to improve production efficiency, the bias circuit of the high voltage unit has

been discontinued and the DC bias voltage has been changed to OV fixed.

∗ Japanese production

This change is effective from 1996 mid-January production.

Chinese production (SOCC)

Running change is effective.

French production (SMF)

Running change is effective.

(6) Abnormal noise sometimes occurs due to the rear cabinet coming in contact with the

base plate when the upper frame is closed. T o alleviate this problem a spacer has been
attached between the lower frame and the base plate to maintain enough space for the
rear cabinet to enter.
