(5) RSPF open/close detection position adjustment
(SIM 41-4)
1) Execute SIM 41-4.
2) Gradually close the RSPF from the full open position, and measure
distance A when the display on the operation panel changes. (See
the figure below.)
Sim41-4 20˚ SENSOR
OCSW
1[128]200 2[128]200
3[128]200 4[128]200
5[128]200
Distance A = Table glass top - RSPF handle rib
A
<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.
(6) RSPF white correction pixel position
adjustment (required in an RSPF model when
replacing the lens unit)
1) Fully open the SPF.
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 display 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.
After sliding the lens unit, perform the OC main scan magnification-
ratio automatic adjustment (SIM 48-1-1) and the RSPF original
off-center adjustment.
This adjustment is basically O.K. with SIM 63-2.
