Was printing paused partway through?

When printing is paused, the coloring at the seam may be altered when printing resumes. Avoid pausing
printing. Before you perform lengthy printing, check the amount of ink remaining. Printing may also pause
when data is not sent from the computer quickly enough. We recommend not performing any other tasks
with the computer while printing is in progress.

Was cleaning performed during printing?

Performing cleaning during printing can affect the print quality. Check the time until cleaning and the
printing time before printing.

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.

Is the media loaded correctly?

If the media is not loaded correctly or the media feed is not smooth, printing may be adversely affected.
Load the media correctly.
