When Printing Becomes Faint or Colors Are Incorrect

When printing becomes faint or colors are incorrect, the print head nozzles on FINE Cartridges are
probably clogged. Print the nozzle check pattern to confirm the condition of the nozzles and then
perform Print Head Cleaning.
If print results are not satisfactory, performing Print Head Alignment may improve print quality.
