1) Set a scale on the OC table as shown below.

2) Make a copy, and use the copied paper as the document and

make a copy from SPF again.

3) Check the copied paper. If an adjustment is required, perform the

following procedures.

4) Execute SIM 50-6.

5) Set the SPF lead edge position set value (Exposure display

<MANUAL> ON) so that the image similar to the adjusted image at
the OC image lead edge position described previously is printed.

1) Execute SIM 41-4.

2) Gradually close the SPF from the full open position, and measure

distance A when the display on the operation panel changes. (See
the figure below.)

Distance A = Table glass top - SPF handle rib

<Spec value>

SPF open/close position A: 125 - 225mm

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.

Note: Since the printed paper is used as the test chart, 
          place the scale in parallel to both sides.
