Printing Maintenance

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 

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 

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 

z Increase the Print Quality setting in the printer driver settings.

If Print Head Deep Cleaning does not resolve the problem, the Print Head may 
be defective. Contact the Customer Care Center.

After print head

nozzle check pattern.
