When Printing Becomes Faint or Colors Are Incorrect

When printing becomes faint or colors are incorrect even if ink remains in the ink tanks, the print
head nozzles 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.
Note
Before performing maintenance
Open the Scanning Unit (Printer Cover) and make sure that all lamps for the ink tanks are lit red.
If not, see "Getting the Ink Status Information" on page 46 and take the appropriate action.
Increase the Print Quality setting in the printer driver settings.
See "Print Results Not Satisfactory" on page 75.
You can also perform the maintenance operation from your computer. For details, refer to the PC
Printing Guide on-screen manual.
