2. Remove the right cabinet.

Remove the screws and open the side door, and remove the rig ht cabi net.

5. Attach the right cabinet.

Reattach the right cabinet to its original position and fix it with the screws.

3. Remove the document glass and the right document glass holder.

Remove the screws, remove the document glass from the copier, and then remove the right document glass holder.

4. Attach t he SPF glass holder.

Fit the SPF glass holder to the document glass. Attach the document glass to the copier and fix it with the screws.

6. Cut out the cut-out portion.

Cut out the cut-out portion of the rear cabinet with nippers or the like. At this time, be careful about the orientation of the nippers so that the cut plane of the rear cabinet is flat.

7. Attach the automatic document feeder.

Insert the hinge portions of the document feeder into the mounting portions of the copier by holding the feeder at an angle toward the rear side.

8. Connect the relay connector.

Connect the harness of the automatic document feeder to the connector of the copier and tighten the screws on the connector.

9. Remove the filament tape.

Remove the filament tape located in the positions shown in the illustration.

Insert the power plug of the copier to the outlet and turn on the main switch of the copier.

11. Check the SPF scanning position switching setting.

• Execute simulation 53-10 (SPF scanning position sw itching setting) and check that the setting value is [1]. (If the value is [0], change it to [1].)

12. Adjust the white compensation pixels.

• Open the automatic document feeder, execute simulation 63-7 referring to the service manual, and adjust the automatic white compensation pixels of the document feeder.

13. Check the copy magnification ratio.

• Set an original on the document glass and copy it. Then, set an original in the document feeder tray and copy it.

• If the magnification rat io of the copy f rom the document feeder is different from that of the copy from the document glass, execute simulation 48-5 to carry out adjustment referring to the service manual.

14. Check the center displacement.

• Set an original on the document glass and copy it. Then, set an original in the document feeder tray and copy it.

• If the center of the copy imag e from the document feeder is different from that of the copy image from the document glass, execute simulation 50-12 to carry out adjustment referring to the service manual.

15. Check the top end position.

• Set an original on the document glass and copy it. Then, set an original in the document feeder tray and copy it.

• If the top end position of the copy image from the document feeder is different from that of the copy image from the document glass, execute simulation 50-06 to carry out adjustment referring to the service manual.

10. Attach the intermediate tray. (AR-RP6N only)

Insert the intermediate tray all the way into the document feeder.

1) Document size detection with the document set tray When documents are set on the document set tray in the auto selection

mode of paper/copy magnification ratio, the document size is detect ed and paper and the copy magnification ratio are automatically selected. When different sizes of documents are set, the max. size is detected. The document width is detected by the document width sensors (W1, W2, W3), and the document length is detected by the d ocument length sensors (L1, L2) to identify the document size. Judgment of the document size is made in a certain timing af ter detecting the doc ument w ith the document set sensor (W0).
