7.5.20 Xerox Image Enhancement (XIE)
Definition
XIE Smoothing is a technology that smooths the jagged lines-most
noticeably on curved, near-vertical, and near-horizontal lines. The
incidence of jagged lines should be noticeably less on prints with XIE
enhancement switched on. See
Figure 7.5.2.2 System Controller Test
Print Pattern for a full-size illustration.
Initial Action:
Ensure that XIE is switched on, in the System Menu (5.1.4.7 System Menu).
Procedure:
1 Run five System Controller test prints, (see
5.1.4.13 Print Menu). Save the last two for analysis
and mark them XIE.
2 Switch OFF XIE and run five prints. Again, save the last two for analysis and mark them XIE off.
3 Use a loupe or other magnifier to compare the prints in step 1 with the prints in step 2 for
differences in jaggy lines on curved, near-vertical, and near-horizontal lines. There is a visual
difference.
Y: Problem resolved, see
NOTE.
N: Replace the System Controller PWB.
NOTE: When the problem has been resolved, return to RAP 7.5.3 Image Quality Checkout to verify that
no other image quality defects exist.
