Table 9-16 Output defects
Description Sample Possible solutions
Output curl:
Printed paper has 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 or
use freshly opened paper.
3. Print in duplex mode.
4. If the problem persists, go to
support.hp.com.
