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.

★ 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.

11) Install the interface harness.

Connect the interface harness from the SPF to the machine and tighten the screws.

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.

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.
