Advanced print cartridge maintenance If you are experiencing problems with printing, you might have a problem with one or both of the print cartridges. You should perform the procedures in the following sections only when directed to do so for resolving print quality issues. Performing the aligning and cleaning procedures unnecessarily can waste ink and shorten the life of the cartridges. If you receive an error message about the print cartridges, see "Print cartridge messages" on page 268 for more information. This section contains the following topics: • Align the print cartridges • Clean the print cartridges • Clean the print cartridge contacts • Clean the area around the ink nozzles Align the print cartridges The product aligns the cartridges every time a new print cartridge is installed. You can also align the print cartridges at any time from the software you installed with the product to help resolve print quality issues. Aligning the print cartridges ensures high-quality output. NOTE: If you remove and reinstall the same print cartridge, the product will not prompt you to align the print cartridges. The product remembers the alignment values for that print cartridge, so you do not need to realign the print cartridges. Work with print cartridges 99
