(15) RSPF scan position auto adjustment
[Function]
Used to adjust the RSPF scan position automatically.
[Operation]
1) With the RSPF or the OC cover open, place a white paper back-
ground on the OC glass. (In the RSPF standard model, the RSPF
glass surface is included.)
2) Enter SIM53-08, and press [START] button.
Outline of SIM: The optical unit is shifted to recognize the bound-
ary between the OC glass and the RSPF glass cover.
With the same position as the reference, the RSPF scan position is
automatically adjusted.
<Note>
• After completion of the RSPF scan position auto adjustment, the
RSPF lead edge adjustment must be executed. (Both surfaces)
• There must be no other sheet than the black chart on the glass sur-
face.
• Especially when in RSPF scan, the center area is scanned in the
main scan direction. Be careful to prevent external light from enter-
ing the scan area.
3) Check that the lead edge is not shifted. (Both surfaces)
(If the original lead edge adjustment has been made properly, even
when the scan position is shifted, it is followed automatically.)
