Edges of objects are stepped or not sharp
If edges of objects or lines appear to be poorly dened 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 45.
Edges of objects are darker than expected
If edges of objects seem darker than expected, 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 45.
Vertical lines of dierent colors
If your print has vertical bands of dierent colors along it:
1. Try using thicker paper, choosing from the recommended paper types such as HP Heavyweight Coated
Paper. See Order paper on page 116.
2. Try using higher print-quality settings (see Printing on page 45). For instance, if you have set the Print
Quality slider to Speed, try setting it to Quality.
White spots on the print
You may notice white spots on the print. This is probably due to paper bers, dust or loose coating material.
To avoid this problem:
1. Try cleaning the paper manually with a brush before printing, to remove any loose bers or particles.
2. Always keep the cover of your printer closed.
3. Protect your paper rolls and sheets by storing them in bags or boxes.
