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 printer's current type of media setting, see page 7-2. Force the automatic cartridge alignment procedure by reseating any one of the print cartridges. If the problem persists, replace the print cartridges. See page 3-25. 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 3-25. 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 printer will run its automatic cartridge alignment procedure - see page 3-26. 9-18
