When Printing Becomes Faint or Colors are Incorrect
When printing becomes faint or colors are incorrect (even if ink remains in the ink tanks), see if
the print head nozzles are clogged and clean them first. Follow the procedures below and
maintain the print head.
Important Before maintaining the print head, check the following:
z Open the front cover and make sure whether the ink tank contains ink. If it is
out of ink, replace it. See “Replacing Ink Tanks” on page 36.
z Ensure that all the orange tape of the ink tank has been peeled off.
z Press “PUSH” on the ink tank and ensure that the ink tank is installed
securely.
z Increase the Print Quality setting in the printer driver settings.
Note If print head maintenance does not resolve the problem, contact the Customer
Care Center.
