Table 9-13 Output defects
Sample Description Possible solutions
Printed pages have curled edges. The curled
edge can be along the short or long side of
the paper. Two types of curl are possible:
● Positive curl: The paper curls toward
the printed side. The defect occurs
in dry environments or when printing
high-coverage pages.
● Negative curl: The paper curls away
from the printed side. The defect
occurs in high-humidity environments
or when printing low-coverage pages.
1. Reprint the document.
2. Positive curl: From the printer control
panel, select a heavier paper type. The
heavier paper type creates a higher
temperature for printing.
Negative curl: From the printer control
panel, select a lighter paper type. The
lighter paper type creates a lower
temperature for printing. Try storing
the paper in a dry environment prior to
use, or use freshly opened paper.
3. Print in duplex mode.
4. If the issue persists, go to
support.hp.com.
