        image


        image

        • The fold unit is adjusted for optimum performance before the finisher is shipped from the factory. Do this adjustment only if the edges of folded booklets are not even.

          1. Switch the copier on and enter the SP mode.

          2. Europe, Asia: Use SP6-134-001 (this is for A3 paper). North America: Use SP6-134-005 (this is for DLT paper).

            image

            • If the original setting of SP6-134-001 or -005 is not "0", then you must do the vertical skew adjustment ("Fold Vertical Skew Adjustment") after you finish this horizontal skew procedure.

          3. Use the 10-key pad to input "-2" (mm) for the SP value. (Press to enter the minus sign.)

          4. Press [#] then exit the SP mode.

          5. Open the front door and pull the stapler unit [A] out of the finisher.

          6. Open the guide plate [B].

          7. Loosen the adjustment screw [C] and then tighten until it stops. (Do not over tighten.)

          8. Remove the lock screw [D].

          9. Raise the tip [E] of the adjustment screw very slightly and allow it to descend under its own weight.

            image

          10. Push the stapler unit into the finisher and close the front door.

          11. Do a folding test.

            • Switch the copier on.

              Booklet Finisher & Finishers (B803/B805/ D373/D374/ D636/D637)

            • Put one page of A3 or DLT paper in the ARDF.

            • On the copier operation panel, select booklet stapling.

            • Press [Start]. One sheet is folded.

          12. Remove the sheet from the lower tray.

          13. Hold the folded sheet with the creased side pointing down and face-up (the same way that it came out of the finisher).

          14. Referring to the diagram, determine if the skew is + [F] or - [G].


            image

          15. Open the front door of the finisher and pull the stapler unit [H] out.

          16. Open the guide plate [I].

          17. Turn the adjustment screw [J] to correct the amount of skew you measured from the test sheet.

            • For + skew [F], turn the adjustment screw (clockwise).

            • For – skew [G], turn the adjustment screw to the left (counter-clockwise).

            • Every click in the +/– direction adjusts the fold position by 0.1 mm by moving the bottom fence [K].

          18. Raise the tip of the adjustment screw [J] and allow it to lower under its own weight.

          19. Attach and tighten the lock screw [L].

          20. Push the stapler unit into the machine, close the front door, then turn the copier on.

          21. Europe, Asia: Do SP6-134-001 (this is for A3 paper). North America: Do SP6-134-005 (this is for DLT paper).

          22. Reset it to "0".

          23. Do the test again.

          24. If the result is satisfactory, this completes the adjustment. -or- If some skew remains, repeat this adjustment.

            image

            • After doing this adjustment, adjust for vertical skew, if necessary. ("Fold Vertical Skew Adjustment")

      6. FOLD VERTICAL SKEW ADJUSTMENT (FOR B804 ONLY)


        image

        • The fold unit is adjusted for optimum performance before the finisher is shipped from the factory. Do this adjustment only if the edges of folded booklets are not even.

          1. Switch the copier on.

          2. Do a folding test.

            • Switch the copier on.

            • Put one page of A3 or DLT paper in the ARDF.

            • On the copier operation panel, select booklet stapling.

            • Press [Start]. One sheet is folded.

              Booklet Finisher & Finishers (B803/B805/ D373/D374/ D636/D637)

          3. Hold the folded sheet with the creased side pointing down, and face-up (the same way that it came out of the finisher).

            image

          4. Referring to the diagram, determine if the skew is positive [A] or negative [B].

          5. Measure the amount of skew.

          6. Enter the SP mode

            • Europe, Asia: Use SP6-134-001 (this is for A3 paper).

            • North America: Use SP6-134-005 (this is for DLT paper).

          7. Enter one-half the measured amount of skew. Example: If the measure amount of skew is

            -1.2 mm, enter -0.6 mm

            image

            • The range for measurement is –3.0 mm to +3.0 mm in 0.2 mm steps for every notch adjustment.

          8. Exit the SP mode and do the test again (steps 2 to 5).

          9. Repeat this procedure until the skew is corrected.

          The illustration below shows the effects of +/- adjustment with SP6113. (The vertical arrows show the direction of paper feed.)

        Paper direction

        The operation of the proof tray and stapler junction gates direct the flow of the paper once it enters

        Proof tray

        Copies are sent to the proof tray (12) when neither sorting nor stapling are selected for the job.


        Upper tray

        Booklet Finisher & Finishers (B803/B805/ D373/D374/ D636/D637)

        The upper tray (11) receives copies that are sorted and shifted and also receives copies that have been corner stapled. Corner stapling is provided on both the B804 and the B805.


        Pre-stack tray

        The pre-stack tray has a switchback mechanism to increase the productivity of stapling. (

        "Pre-Stacking) Pre-stacking is done for corner stapling in the B804/B805 and for booklet stapling in the B804.


        Lower tray

        The lower tray (7) receives copies that have been center folded and stapled (booklet stapling). Booklet stapling is not provided on the B805.
