Edges of objects are stepped or not sharp
1. If edges of objects or lines appear to be poorly dened or lighter in density, and you have already set the
print-quality slider to Quality in the driver dialog, select the custom print-quality options, and try setting the
quality level to Normal. See Printing on page 59.
2. Alternatively, set print quality to Custom options, then Settings: Best and check the More passes box. This
will cause unidirectional printing, which reduces the severity of the problem.
3. The issue may be related to orientation. Try rotating the image: you may nd that the result looks better.

Horizontal lines at the end of a cut sheet print
This type of defect aects only the end of a print, within approximately 30 mm of the trailing edge of the paper.
You may see some very thin horizontal lines across the print.
To avoid this problem:
1. Consider using larger margins around your image.
2. Print the Image Diagnostics Print. See Image Diagnostics Print on page 175.
3. Consider printing with roll paper.
