Troubleshooting
Solving Print-Quality Problems

If There are Jagged Vertical or Horizontal Lines

Did you specify the right media type when loading the media? For details of
front-panel media types, see page 3-3. To find out the plotter's current type of
media setting, see page 7-2.
Force the automatic cartridge alignment procedure by reseating a print
cartridge.
If the problem persists, replace the print cartridge(s). See page 3-26.

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 11-4.
If There are Color "Shadows"
Force the automatic cartridge alignment procedure by reseating any one of the
print cartridges.

If One or More Cartridges are not Printing at All

Look to see if the cartridge is out of ink. See 3-26.
If it is still not printing, remove the faulty cartridge(s) and check the print
nozzles to make sure the protective tape has been removed. Do not forget that,
after you remove or reseat a cartridge, the plotter will run its automatic cartridge
alignment procedure – see page 3-27.
