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. Follow the procedures below to clean the nozzles.
If the ruled lines are shifted after running the print head maintenance, align the Print Head.
Before printing the nozzle check pattern or cleaning the Print Head, check the
following;
z Open the Top Cover and make sure that all the ink tanks click into place and
then their ink lamps light red.
If any one of the ink lamps is flashing slowly, the associated ink tank is
running low. You can continue printing, but we recommend preparing a new
ink tank to replace the associated ink tank.
If any one of the ink lamps is flashing quickly, the associated ink tank is
empty. Replace the ink tank. See “Replacing Ink Tanks” on page 41.
If an ink lamp is flashing even though ink remains in that ink tank, it is
inserted in the wrong position. Make sure that the correct ink tank color is
inserted in each position referring to the color guide on the print head lock
lever. See “Replacing an Ink Tank” on page 36.
If any one of the ink lamps is unlit, press the mark on the ink tank to fully
insert it. Make sure that all packaging material is peeled off the ink tank. See
“Replacing Ink Tanks” on page 41.
z Increase the Print Quality setting in the printer driver settings.
See “Print Results Not Satisfactory or Contains Errors” on page 65.
If Print Head Deep Cleaning does not resolve the problem, the Print Head may
be defective. Contact the Customer Care Center.
