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 the ruled lines are shifted after running print head maintenance, align the Print Head.
Note
Before performing maintenance
zOpen the Top Cover and make sure that all lamps for the ink tanks are lit red.
–If any one of the lamps is flashing slowly, the associated ink tank is running low. You can continue printing for a while, but we recommend you to have a replacement ink tank available.
–If any one of the lamps is flashing fast, the associated ink tank is empty. Replace the ink tank. See “Replacing Ink Tanks” on page 31.
If an ink lamp is flashing fast even though ink remains in that ink tank, it is inserted in the wrong position. Make sure that the ink tank of the correct color is inserted in each position, matching the label. See “Replacing an Ink Tank” on page 26.
–If the ink tank lamp is not lit, the tank is not set properly. Press the 
mark on the ink tank until the tank clicks into place. Make sure that all packaging material is peeled off the ink tank. See “Prepare the replacement tank.” on page 32.
zIncrease the Print Quality setting in the printer driver settings. See “Print Results Not Satisfactory” on page 64.
