4.3 Troubleshooting for Image Quality
REGIUS MODEL 190 Service Manual Ver.1.00 2004.11.01
4.3.12 Case 11: The left and right of the image are disconnected.
• If problems from cases 10 and 11 above repeats after resolution, inform to the manufacturer.
4.3.13 Case 12: Irregularity correction has not been carried out.
• Confirm whether images are being obtained without correction.
• Confirm that the ADB2's high-voltage switch is turned ON.
4.3.14 Case 13: The irregularity correction data is excessive (i.e., 300 steps or more
from MAX to MIN)
Phenomena Cause/Remedy
1 The X-ray exposure restriction is not suit-
able.
Check the exposure field.
2 The sideways-direction start point is not cor-
rect.
Check the sideways-direction start point and modify if neces-
sary.
Phenomena Cause/Remedy
1 The image data for creation of irregularity
correction is bad.
Recreate the irregularity correction using a plate with no sur-
face damage or contamination.
2 If the problem persists after performing the
above.
• Replace the CF card.
• Replace the SCB2. "2.7.3 Replacement of SCB2
(System Control Board), p.84"
Phenomena Cause/Remedy
1 Exposure conditions for the irregularity correc-
tion are not suitable.
Repeat with appropriate exposure condition.
2 Plates or the optical unit's beam collector sec-
tion is soiled.
Clean the soil.
3 Foreign objects are exposed in the correction
image.
Repeat the exposure avoiding any object to be included
in the imaging field.
4 Polygon correction is made excessively. (300
steps or more)
When this remains large even after irregularity correction
is repeated, replace the optical unit. "2.6.2 Replacement
of Optical Unit, p.76"
