• Streaks or partial characters in printing: Clean cartridge contacts (copper electronic circuitry) with warm water. Also clean contacts in printer carriage according to your printer's manual, then snap the cartridge in and out a few times to assure a good connection.
• Cartridge appears clogged: Run print head only under warm tap water for a minute. Dry all excess water from cartridge and replace cartridge in printer. This will usually dissolve any dried ink in the print head, which may cause clogging.
• Other printing problems: Many printing problems are not related to the cartridge. Particularly with inkjet printing, the media (paper source) has a great deal to do with print quality. Check your media carefully for print quality before using it in your inkjet printer. Software and hardware problems can also contribute to print quality, color reproduction, etc. Your printer's manual will have many suggestions for both cleaning and maintaining your printer. Please refer to the manual when you have a printing problem.
