5.
Make sure that “RESULT-OK” appears on screen.
6.
Using menus “TEST”, “Image Format” or “Image Format - 2”, and
“SINGLE”, read one of the IPs prepared in step 1, and generate an
image output.
u
INSTRUCTION
u
Be sure to follow the instruction mentioned in “20.2 Image/Conveyance Checks”
when outputting the image.
{MC:20.2 _Image/Conveyance Checks}
7.
Verify that there is no white blank portion and the resulting image is
not cut off.

NOTE
u
If anything abnormal is found with the image:
{Troubleshooting}
8.
Back up the data so adjusted into a floppy diskette.
{MC:19.1 _Backing Up the Scanner Data}
16.1.2 Main Scan Length (Freq) Adjustment
u
NOTE
u
To adjust the main scan length, expose an IP to radiation while using a steel rule or
other thin article. If you use a tester or other thick article, the resulting image is larger
than the actual size so that the main scan length cannot be properly adjusted.
1.
Place a 175mm-length steel rule on an IP of 14” x 14” (35cm x 35cm)
or 14” x 17” (35cm x 43cm) size, and expose it with the tungsten X-ray
tube at about 1 mR.
u
INSTRUCTION
u
At least two IPs should be exposed for checks before and after the adjustment.
2.
Using menus “TEST”, “Image Format” or “Image Format - 2”, and
“SINGLE”, read one of the IPs prepared in step 1, and generate an
image output.
{MC:20.2 _Image/Conveyance Checks}
3.
Measure a misalignment of the reading width.
Measure the actual size of the 175mm-length steel rule and the size of the white
blank portion, and calculate an adjustment value in accordance with the formula
shown below.
--- Example ---
If the measured value of the reading width is 170 mm when an IP of 14"x14" (35cm
x 35cm) size is outputted to a 14" x17" (35cm x 43cm) film:
(175 - (170/1))/175x100 = 2.8 (%)
Thus, "Input range" is +2.8.
