1.MEASURE T O PREVENT W-FEED IN G OF THE ORIGINAL DOC UM ENT.
2.ESTABLISHMENT OF PARTS AS A MEASURE TO PREVENT PROBLEMS OF CRIMPING OF THE ORIGINAL DOCUMENT.
1. Measure to prevent W-feeding of the original document.
1.Model Name: SF-A15/A16
2.General: The measure described below has been carried out as a measure to improve problems
of W-feeding of the original document.
3.Description: Separator plate springs have been stacked double for both F and R as a measure to maintain the overwrap volume between the separator belt and the feeder roller and stabilize the paper smoothing performance when a problem of W-feeding occurs.
The cushion mylar sheet has been discontinued and the cushion has thus been left
bare as a measure to increase the friction resistance. This change has been carried out as a measure to prevent W-feeding of the last two pages of the original document. (Note : As a market action for machines which were produced before 1996 October , it is possible to avoid problems by attaching a cushion on top of the cushion mylar sheet which is currently installed.)

Cushion mylar sheet Only the cushion has been changed.

[Sequence for installing original document retainer parts]
1. Detach and remove old parts.
1) Turn the power supply of the copy machine OFF.
2) Open the ADF. Detach the retainer roller stay assembly by removing the two screws
attaching it (two locations, one on each of the left and right sides). Remove the belt retainer roller holder (F side) and belt roller holder (R side) 2 which secure the front and rear sides of the D belt retainer roller 3, and remove the D belt retainer roller. (Note: The screws which were removed will be used later, and should therefore not be lost.
(2, and 3 are for model SF-A54 only.)
(Figure - 1)
2. Attach newly established parts.
1) Assemble and attach the retainer roller stay N (0CW2158P171E), which is to function
in place of the retainer bearing spring 36, retainer holder 37, retainer holder-2 38, and retainer bearing 39 from the retainer roller stay assembly which was detached in 1-2) above.
2) Attach the retainer plate plate spring (0CW2176P152A) to the retainer roller
stay N with two S2 screws (M3 x 6 IT tap tight 0CW030060FZTP).
3) Attach one retainer bearing (0CW2158P035A) to each of the two retainer bearing
springs (0CW2198P106A), and attach the retainer plate plate spring ➃ with one S3 screw (M3 x 4 IT screw, 0CW03004FZIT).
(Figure - 2)
3. Assemble and attach.
1) Using the removed screw (1) , attach the DF spacer (0CW2158P034A) to the
location where the belt roller holder (2) which was removed in 1-2) above was attached.
2) Using the screws 75 which secured the retainer roller stay from 1-1) above, attach
the retainer roller stay N (two assembled units) which were assembled in 2-1) above to the ADF . When attaching the retainer roller stay N to the ADF, the roller stay N on the right side in 2-3) above (with the plate spring and bearing assembled) should always be attached to the paper delivery side (the right side). Note: Care should be exercised to insure that the bearing attached to the retainer
roller stay N does not become detached. Caution should also be exercised to prevent the delivery belt from tearing.
3) Attach the retainer holder F (0CW2158P054B) and the retainer holder R
(0CW2158P055B) with two S1 screws (M3 x 6 IT screws, 0CW030060FXIT).
