3. Document size detection

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

tion mode of paper/copy magnification ratio, the document size is
detected 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
document length sensors (L1, L2) to identify the document size.
Judgement of the document size is made in a certain timing after
detecting the document with the document set sensor (W0).

2) Execute SIM 63-2.

3) When the operation panel displays "COMPLETE," the adjustment
is completed.

4) If the operation panel displays "ERROR," perform the following
measures.

· When the di splay is 0: Check that the SPF is open.

Check that the lamp is ON. (If the lamp is OFF, check the MCU
con-nector.) Check that the CCD harness is properly inserted into
the MCU con-nector.

· When the display is 281 or above:

1) Remove the table glass.

2) Remove the dark box.

3) Slide the lens unit toward the front side and attach it, then

exe-cute SIM.

· When the display is 143 or below:

1) Remove the table glass.

2) Remove the dark box.

3) Slide the lens unit toward the rear side and attach it, then

execute SIM.

<Spec value>

3) If the distance is outside the specified range, adjust the open/close
sensor attachment plate position as shown below.

· Distance < 125mm: Shift toward A.

· Distance > 225mm: Shift toward B.
