To adjust part-to-part varia-
tions in accuracy of IR parts
and their mounting accuracy
by varying the scan start
position in the CD direction.
When the CCD Unit is
replaced.
When the Original Glass is
replaced.
• With a scale placed in parallel with the
Original Width Scale and with the lead-
ing edge of the scale pressed up
against the Original Length Scale, make
a copy of the scale.
• Because of a void amount involved with
the engine side, the image is automati-
cally slid 50 mm toward the left as it is
produced on the copy.
• Adjust so that the scan starts with the
position of 0 mm (on the graduations) at

To adjust variations in mount-
ing accuracy and sensitivity
of the Scanner Home Sensor
and in mounting accuracy of
the Original Width Scale by
varying the scan start posi-
tion in the CD direction.
When the Original Glass or
Original Width Scale is
replaced.
• With a scale placed in parallel with the
Original Length Scale and with the lead-
ing edge of the scale pressed up
against the Original Width Scale, make
a copy of the scale.
• Sinceavoidimageoccursonthecopy
corresponding to the 0 mm portion of
the scale due to the shadow of the Orig-
inal Width Scale and Original Glass, a
void of 10 mm is forcibly produced of
the data.
• Adjust so that the scan starts with the
position of 10 mm (on the graduations)
of the scale as checked with the image
on the copy.

To correct an error in the
zoomratiointheCDdirec-
tion occurring due to varia-
tions in mounting accuracy of
the CCD, lens, and other
parts by varying the number
of readings in the CD direc-
tion.
When the CCD Unit is
replaced.
The adjustment of “Zoom
for FD” of “PRT Area” must
be completed.
• Place a scale on the Original Glass in
the CD direction and make a copy of the
scale. Measure the length of the scale
on the copy to see if it measures 200
mm
± 1.
• If the measured value falls outside the
specified range, enter the correction
value by the following formula: specified
value/measured value.
