9.3 Automatically cleaning print cartridges
If your printed pages are missing lines or dots, or if they contain ink streaks, the print
cartridges might be low on ink or might need to be cleaned.
If the print cartridges are not low on ink, follow these steps to clean the print
cartridges automatically:
1. Open the printer Toolbox.
2. Click Clean the Print Cartridges.
3. Click Clean, and then follow the onscreen instructions.
If your documents are still missing lines or dots after cleaning, replace the print
cartridges.
Caution: Clean print cartridges only when necessary. Unnecessary cleaning
wastes ink and shortens the life of the cartridge.
