Many factors can affect the quality of the print. The following are listed in order from most likely to least likely:
1. Quality Setting. There are three printer settings which can affect quality. (Section 4B)- Print Quality - Increase to Better or Best.- Color Matching - Set to Vivid Photos for Best Quality- Enable Bi-di Printing - Set to "No" for Best Quality2. Clean the Cartridge. Run an automatic cleaning print from PrintHub or manually clean the cartridge as described in Section 6B of the manual.3. Change the Cartridge. Try a new cartridge. Make sure that the ink cartridge has ink remaining. Check the ink levels via the PrintHub or Printer Utility (Mac).4. Align Print Head. Normally, print head alignment is only necessary after changing an ink cartridge. However, in certain cases, running the alignment again can improve print quality. Align the print head by opening PrintHub or Printer Utility (Mac). Click on the Align Print Head icon below the ink levels. Follow the onscreen prompts to load your paper for alignment.
5. Clean the Maintenance Area. Power off the printer! Gently move the cartridge to the left to access the maintenance area. This includes the rubber cartridge nozzle cap and the plastic roller. Under normal use this can become dirty with ink. Clean with a paper towel dampened with rubbing alchohol.6. Copper Contacts. Clean the copper contacts on the back of the cartridge carrier and the corresponding contacts on the ink cartridge with a paper towel dampened with rubbing alcohol.7. Image Resolution (DPI). Try another image. Perhaps the resolution of the current image is not sufficient for a quality print. We recommend a 300 DPI image. Images less than 150 DPI may print pixelated.8. Cable. Try another USB cable. Make sure that it is less than 6 feet (2 meters) long. Faulty cables or cables that are too long interrupt communications which can result in print quality issues.
