If there are jagged vertical or horizontal lines
If the problem is only with black or gray lines, check that you are using the
correct settings to achieve printing at 600 dpi (see page 3–14).
If problem is only with vertical black or gray lines, run the Black Cartridge
Alignment Procedure, explained on page 5–4.
If problem is with any other color or orientation, run the Color Cartridge Test
procedure, explained on page 5–8.
If there are slightly warped lines
The media itself may be warped. This can happen if it has been used or stored
in an extreme environment. For all environmental specifications, see page
10–5.
If there are color “shadows”
In the example on the left, a magenta “shadow”, which is not part of the drawing,
appears at the edge of a blue object.
The cartridges need to be re-aligned. Run the Color Cartridge Test procedure,
explained on page 5–8.
If a cartridge is not printing at all
Remove the faulty cartridge and check the print nozzles to make sure the
protective tape has been removed.
Look to see if the cartridge is out of ink. See page 7–2.
Try priming the cartridge to clear the nozzles. See page 7–7.
If the print quality appears to be poor just in one part of the
print
Did you raise the cover during printing? Although the print continues after the
interruption, the print quality in the area of the interruption cannot be
guaranteed.
