4.3 Troubleshooting for Image Quality
REGIUS MODEL 190 Service Manual Ver.1.00 2004.11.01
4.3.23 Case 22: Image duplication
4.3.24 Case 23: Sensitivity correction is not within the specified range
4.3.25 Case 24: All post-processing images have high contrast.
4.3.26 Case 25: All post-processing images have low contrast.
Remedy
1
Check the erase lamp is operating during the erasure process.
2 • Erase and then carry out reading without using any correction.
• If the problem repeats, replace the pate (as large doses have caused the plate to break).
This operation is to be carried out with correction.
Remedy
1 Check whether the correction image's exposure conditions and input values are correct.
Phenomena Cause/Remedy
1
A high overall contrast is set for the process-
ing parameter of output density. • Set the output density "H" of G-Value/Shift parameters to
a lower value.
• Set the output density "L" of G-Value/Shift parameters to
higher value.
For more details, refer to the Image Processing Adjust-
ment Manual.
