Chapter 3 Troubleshooting
3-45
3.4.10 Image Size is Different (Horizontally)
3.4.11 Top and Bottom of the Image is Trimmed
3.4.12 Sides of the Image is Trimmed
• Communicate the contact if it recur after the response.
3.4.13 Unevenness is Not calibrated
• Confirm if the image can be acquired without correction.
• Confirm if the high voltage switch on LMC is ON.
3.4.14 Unevenness Calibration Data is Too High (MAX-MIN is Over 300
Steps)
No. Cause Response
1 Image size setup value was replaced. Confirm and correct the image size setup value.
No. Cause Response
1 Aperture of the X-ray is not appropriate. Confirm the exposure field.
No. Cause Response
1 Aperture of the X-ray is not appropriate. Confirm the exposure field.
2 Horizontal start point is not appropriate. Confirm and change the horizontal start point.
No. Cause Response
1 Image data used for unevenness
calibration was faulty.
Redo the unevenness calibration with a plate without
any scratch or smudge.
2 (Does not improve after performing the
above action)
• Replace the CF card.
See "5.10.3 Replacing the CF Card (Page 5-118)"
for the procedure to replace the CF card.
• Replace the CIU.
See "5.10.1 Replacing the CIU (Page 5-115)" for
the procedure to replace the CIU.
Im
ortant
Always perform the image size adjustment, the image position adjustment, the unevenness
calibration, and the sensitivity calibration after replacing the optical unit.
No. Cause Response
1 Exposure condition of the image used in
the unevenness calibration is not
appropriate.
Redo the exposure with appropriate exposure
condition.
2 Plate or the light condensing unit in the
optical unit is dirty.
Clean the plate and the light condensing unit in the
optical unit.
3 Object was exposed on the image that
was used for the unevenness calibration.
Redo the exposure without any object getting
exposed.
4 Polygon correction data is too large
(over 300 steps)
Replace the optical unit if it is still large after redoing
the unevenness calibration.
See "5.2.5 Removing/Installing the Optical Unit (Page
5-11)" for the procedure to replace the optical unit.
