Margins and skew:
The image is not centered or is skewed on
the page. The defect occurs when the paper
is not positioned properly as it is pulled from
the tray and moves through the paper path.
1. Reprint the document.
2. Remove the paper and then reload
the tray. Make sure that all the paper
edges are even on all sides.
3. Make sure that the top of the paper
stack is below the tray full indicator.
Do not overfill the tray.

adjusted to the correct size for the

Table 7-13 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 EWS,
select a heavier paper type. The
heavier paper type creates a higher
temperature for printing.
Negative curl: From the printer EWS,
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. Visit hp.com/support if the problem
persists.

conditions can cause this defect:
● Extreme paper curl
● The paper in the tray is wrinkled or
deformed
● The paper is a non-standard paper
type, such as envelopes
● The output tray is too full
1. Reprint the document.
2. Extend the output bin extension.
3. If the defect is caused by

troubleshooting steps for Output curl.
4. Use a different paper type.
