Did you pause printing?
When printing is paused, the coloring at the seam may be altered when printing resumes. Avoid pausing print-
ing. Under factory default settings, printing pauses when an ink pouch runs out. Before you perform lengthy
printing, check the amount of ink remaining in the ink pouches. 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.
Is the media loaded correctly?
If the media is not loaded correctly or media feed is not smooth, printing results may be adversely affected.
Load the media correctly.

Have you not printed for a while?
If printing is not performed for several days, printed colors may become unstable or uneven, e.g., when color
density is inconsistent, even if the same data is printed with the same settings.
In such cases, shaking the ink pouches, performing light choke cleaning, and refreshing the subtanks can be
effective. (The light choke cleaning and subtank refresh procedures consume large quantities of ink. Read the
instructions in this manual carefully and undertake these procedures with caution.)
