Unwanted white streaks appear at regular intervals in area fills
These white lines may result from a mismatch between adjacent
passes of the print heads
Check that the X-priority is set to X-alignment, and not X-accuracy.
Then adjust the X alignment value, if necessary (see 'To enter the
adjustment value' on page 91)
Blocked nozzles on the print heads
Clean the print heads to make sure all the nozzles function correctly
(see 'Cleaning the print heads' on page 133).
Ink smears on the media
The print head comes into contact with the media, due to media
wrinkles or bubbles during printing
Allow absorbent media (paper) time to adjust to the same environ-
ment as the printer before printing. Set the print head height to a
higher level, if necessary (see 'Adjusting the carriage height' on
page 146).
Dirty wiper blades, or dirty wiper component at the bottom of the
carriage
Clean the wiper blades, or the bottom wiper component (see 'Caring
for the wiper blades' on page 130)
Prints with large area fills
Use the recommended media that is appropriate for area fills (see
'Choosing media' on page 123)
Parts of a drawing are missing
Can be due to dirt or buildup of paper debris
Clean the print heads (see 'Cleaning the print heads' on page 133)
