Table 9-7 Image placement defects
Sample Description Possible solutions
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.
4. Make sure that the paper guides are
adjusted to the correct size for the
paper. Do not adjust the paper guides
tightly against the paper stack. Adjust
them to the indentations or markings
in the tray.
