Try the following suggestions to avoid this problem:
1. Check that the paper type you have loaded corresponds to the paper type selected in the front
panel and in your software. See View information about the paper on page 39 .
2. Use a recommended paper type (see Order paper on page 91 ) and the correct print settings.
3. If using sheet paper, try rotating the sheet 90 degrees. The orientation of the paper fibers may
affect performance.
4. Try changing to a thicker paper type, such as HP Heavyweight Coated Paper.
5. Select a paper type that is slightly thinner than the paper you have loaded; this will persuade the
printer to use less ink. Here are some example paper types in ascending order of thickness: Plain
Paper, Coated Paper, Heavyweight Coated Paper.
6. Try to increase the margins by relocating the image to the center of the page using your software
application.
Ink marks on the back of the paper
Clean the platen with a soft cloth. Clean each rib separately.
Black ink comes off when you touch the print
This problem may be caused by printing with matte black ink on glossy paper. The printer will not use
matte black ink if it knows that the paper will not retain it. To be sure of avoiding matte black ink, you
can select Photo Glossy Paper as the paper type (in the Photo Paper category).
Edges of objects are stepped or not sharp
If edges of objects or lines appear to be poorly defined 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 Speed. See Printing on page 42 .
