When Printing Becomes Faint Or Colors Are Incorrect - Canon PIXMA iP3500 Series Quick Start Manual

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 Top Cover and make sure that all lamps for the ink tanks are lit red.
If not, see "Getting the Ink Status Information" on page 23 and take the appropriate action.
Make sure that the ink tank is set properly. See "Replacing Ink Tanks" on page 25.
Make sure that all the orange tapes have been peeled off.
If the ALARM lamp flashes orange, see "ALARM Lamp Flashes Orange" on page 64.
Increase the Print Quality setting in the printer driver settings.
