[5] Checks on Adjustment Results
Have on hand two 150mm steel rules, and measure their outer lengths.
(1) Power ON the machine.
Make sure that the machine starts up normally.
(2) With the steel rules placed in the same position on the cassette as during adjustment,
uniformly expose a 14" x 14" (35cm x 35cm) or 14" x 17" (35cm x 43cm) IP at about 1
mR.
(3) Perform recording under SENSITIVITY of the IDT's Test Menu, and generate image
output.
(4) Check the following points with the output film.
• Measure the dimension of the image of the steel rules to check that the image length
in the main-scan direction has an error of ±1mm or less relative to the following
correction value.
• Check that the top/bottom and right/left blank portions around the image are all 2mm
or less in actual size on the IP.
SUPPLEMENTARY NOTE
The white blank portions can be adjusted by setting the image trimming.
(5) Quit the adjustment of the read width and read start position.
Only if anything abnormal is found with the output film, or the adjustment result is out
of specification, perform the steps described in "[6] Fine Adjustment of Read Width and
Read Start Position" below.
[6] Fine Adjustment of Read Width and Read Start Position
The procedures for finely adjusting the read width and read start position are described
below.
After fine adjustment, perform the steps described in "[5] Check on Adjustment Results"
again.
NOTE
After the adjustment, be sure to save the data to the hard disk by selecting "MAINTENANCE
UTILITY", "5. SCANNER UTILITY", "8. DATA MANAGEMENT", and "3. SAVE FORMAT
DATA" in sequence.
Adjustment of read width
(1) Activate M-Utility.
" Activating and Exiting M-Utility"
(2) Select "5. SCANNER UTILITY", "6. FORMAT" and "2. FREQ ADJUST" in sequence.
(3) Enter the correction value and press the [ ENT ] key.
Use the following input data.
• To increment the current read width by N% (0 < N ≤ 5) (to enlarge the image)
• To decrement the current read width by N% (-5 < N ≤ 0) (to reduce the image)

Correction value = 150 (mm) x (1 + 23.5/d)
where d (mm) is the distance from the tube to the front cover of the exposure
unit.
