Shake new ink pouches gently before you install them.
If the media is wrinkled and comes loose from the platen, colors
may be uneven or the printing quality may suffer.
P. 177 "Media Feed Is Not Smooth"
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 pouch becomes
empty. 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.
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.
If the media is not loaded correctly or the media feed is not
smooth, printing may be adversely affected. Load the media
correctly.
P. 177 "Media Feed Is Not Smooth"
Depending on the settings for such menu items as [FULL WIDTH
S] and [PERIODIC CL.], uneven colors may occur. If the settings
have been changed, try restoring them to their default values.

P. 133 "Preventing Soiling of the Media and Dot Drop-Out"
If the settings selected with the [PRESET] menu item are not
suitable for the type of media, output may be adversely affected.
Choose settings optimized to the media you are using.
