3. If there is no skew but the problem persists, clean and calibrate the scanner see Preventive maintenance
on page 529 to see how to clean the scanner, and see Support Menus, Diagnostic Plots & Calibrations
on page 181 to see how to Calibrate the scanner. See "Scanner Maintenance" in the user guide for more
information. Take care not to move the printer during the calibration, and check that the maintenance
sheet is correctly positioned before starting the calibration. Also check that the maintenance sheet is
not damaged before calibrating the scanner (an old or damaged maintenance sheet may cause this
problem); if it is damaged, reprint it.
4. If the problem persists, proceed to analyze the following areas of the diagnostic plot:
●
D, H and L (for three modules, 0-Left, 1-Middle, and 2-Right and its intersection).
The two vertical thin black lines at the beginning and the end of the diagnostic plot show, approximately, the
position of the intersection between Scanbars, where this kind of error usually appears. If the error appears
outside these areas and the line discontinuity varies along the plot try to recalibrate the OPT wheel. See
Support Menus, Diagnostic Plots & Calibrations on page 181.
If unsuccessful try to reset the Scanbars. If the problem persists replace the OPT Wheel F9A30-60038
on page 453 and recalibrate it again. If the problem still persists replace the Scanbars.
Light colored area lls are missing in the scan or copy
When scanning or copying a map with a light are ll in the top of the plot, the Background color removal
setting could interpret it as a color in the background and may remove it, together will the lighter area lls.
This could cause some light area lls to disappear. The example below shows the original image on the left
and the scanned image on the right.
