9) Install the SPF harness and the ring core
(included together with the unit).
Pass the SPF harness through the plate hole from the above and fix it
to the plate with the supplied two hex cap screws. (➀)
Pass the SPF harness through the ring core (➁), and connect it to the
main PWB connector (CN11) inside the copier. (➂)
Be careful about the direction
of the connector.
10) Install the SPF to the copier.
Tilt the SPF backward and insert the hinges into the hinge guides.
12) Remove the filament tape.
Remove the filament tape at four positions.
Connect the power cord, turn the main switch ON, and
perform the following procedure.
13) Check the magnification ratio.
• Place a document on the document glass and make a copy.
Then, place a document in the automatic document feeder tray
and make a copy.
• If the copy magnification ratio of the copy made with the automatic
document feeder is different than that of the copy image made with
the document glass,perform the magnification adjustment according to the procedure in the service manual.
14) Check the center displacement.
• Place a document on the document glass and make a copy.
Then, place a document in the automatic document feeder tray
and make a copy.
• If the center of the copy from the automatic document feeder is
displaced from the copy from the document glass, adjust the center according to the procedure in the service manual.
15) Check the leading edge margin.
• Place a document on the document glass and make a copy.
Then, place a document in the automatic document feeder tray
and make a copy.
• If the leading edge margin of the copy from the automatic docu-
ment feeder is displaced from the copy from the document glass,
adjust the margin according to the procedure in the service
manual.
16) Check the open/close detection position.
(only models with original size detection)
• If the open/close detection position measured by the open/close
detection position adjustment method in the service manual is outside the specified values, adjust the position in accordance with
the manual.
11) Install the interface harness.
Connect the interface harness from the SPF to the machine and
tighten the screws.

3. Document size detection
Document size detection by document set tray
When a document is set on the document set tray in the auto mode of
paper/copy magnification ratio selection, the document size is
detected to perform the auto selection function of paper and the copy
magnification ratio according to the detected document size.
When documents of different sizes are mixed and set on the tray, 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 document length sensors (L1, L2) to determine the
document size.
The document size judgment is made after a certain time from when
the document set sensor (W0) detects the document.
