affected. Make sure the media is loaded and set up correctly.

Is the printer installed in a level and stable location?
Never install the machine in a location where it is tilted or where it may wobble or experience vibration. Also
make sure that the print heads are not exposed to moving air. These factors may lead to dot drop-out or
reduced printing quality.
Was printing paused partway through?
When printing is paused, the coloring at the seam may be altered when printing resumes. Avoid pausing
printing. With the factory default settings, printing pauses when an ink cartridge becomes empty.
Before you perform lengthy printing, check the amount of ink remaining in the ink cartridges.
 P. 103, "Checking the Amount of Remaining Ink"
Printing may also pause when data is not sent from the computer quickly enough. We recommend not per-
forming any other tasks with the computer while printing is in progress.
