Misaligned colors If the colors are misaligned in any direction, the printheads may be misaligned. This is likely if you have not aligned the printheads for a long time, or if there has been a substrate jam. Align the printheads if necessary (see Align the printheads on page 146). You can check whether it is necessary by printing the printhead alignment status plot (see 3. Printhead alignment status plot on page 114). Color variation and text-line correction If some printhead nozzles are in use while others in the same printhead are not, water evaporates slowly from the ink in the unused nozzles, making the color more intense. Thus, in such cases you may notice variations in color intensity in areas where the color of the image should be constant. If you notice such a problem, there are various possible solutions. 1. If you notice the variation in intensity near one side of the print, try rotating the image by 180 degrees before printing. This may solve the problem in some cases, as all the nozzles are refreshed whenever they enter the service station between passes. 120 Chapter 5 Troubleshoot print-quality issues ENWW

Misaligned colors
If the colors are misaligned in any direction, the printheads may be misaligned. This is likely if you have not
aligned the printheads for a long time, or if there has been a substrate jam. Align the printheads if necessary (see
Align the printheads
on page
146
). You can check whether it is necessary by printing the printhead alignment
status plot (see
3. Printhead alignment status plot
on page

).
Color variation and text-line correction
If some printhead nozzles are in use while others in the same printhead are not, water evaporates slowly from
the ink in the unused nozzles, making the color more intense. Thus, in such cases you may notice variations in
color intensity in areas where the color of the image should be constant.
If you notice such a problem, there are various possible solutions.
1.
If you notice the variation in intensity near one side of the print, try rotating the image by 180 degrees
before printing. This may solve the problem in some cases, as all the nozzles are refreshed whenever they
enter the service station between passes.
