[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).

The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder.
The alphabet following the LF mark shows the kind of lead-free solder.

(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a breakdown or an
accident.
Since the melting point of lead-free solder t hread is about 40°C higher than that of conventional lead solder thread, the use of the exclusive-use soldering iron is recommendable.

(2) NOTE FOR SOLDERING WORK
Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, a nd its soldering capacity
is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. Th is may cause land separation or may
exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when completion of soldering is
confirmed.
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean t he soldering iron t ip aft er com-
pletion of soldering work.
If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.
