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. ➀ Units which have had a spacer

➁ Units which have had changes in

the shape of the metal plate carried out in accordance with a change in the metal molds.

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.

This change is effective from the start of mass production.

French production (SMF)

This change is effective from 1996 mid-January production.

(8) To carry out adjustments on the height of the fusing paper guide, action such as the

addition of height adjustment springs and spacers to the height blocks had been carried out. Because proper height settings could not be easily established, and because problems of large deviations in the height occurred, an adjustment plate has been added to enable successive and simple height adjustments.

The installation procedures for the P/G height adjustment plate are described below. Please refer to the operations procedures when carrying out the action described above.

1. Action for side F a. Press the bent portion (standard A) of the adjustment plate to the metal plate section

of the fusing upper frame. Note: It is essential to make sure that the metal plate is in proper contact with the frame because the height and direction positions of block F are determined in accordance with the contact with the frame.

b. The positioning protrusion of elevation block F should be aligned with the holes in

the adjustment plate (standard B) and secured with the upper frame by M3 x 8 screws.

2. Action for side R a. Secure elevation block R to the top side with M3 x 8 screws. The block should be

secured to the amount of looseness.

3. Adjustment procedures. a. By loosening the nut and rotating the stopper screw, the length of the extended

portion of the screw can be changed to adjust the height.

b. The height of the P/G is adjusted in accordance with the passing and stopping of the

adjustment tool.

c. Aft er adjustment procedures have been completed, tighten the nut, and take up any

slack with the upper and lower locking screws (2 locations).
