Set the print quality to normal or best.
Clean the printhead
Run a calibration.
The Kodak EasyShare AiO performs a calibration every time you install or replace a printhead. However, you can run a calibration if you are seeing changes in the image quality. Calibration aligns the printheads and performs a nozzle health check to enable high-quality prints.
1 Load the main tray or photo tray with photo paper.
IMPORTANT: If you don't have any photo paper, you can use plain paper, but photo paper is highly recommended for calibrations.
2 Press and hold Photo and Cancel together to make a calibration print.
3 Follow the instructions on the calibration print to calibrate the printer.
