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.

Note

Before printing the nozzle check pattern or cleaning the Print Head, check the following;

Open the Scanning Unit (Printer Cover), and make sure that all the ink tanks click into place and then their lamps light red.

If any one of the lamps is flashing, the associated ink tank is empty or running low. See “Getting the Ink Level Information” on page 108.

If an ink tank 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. Open the Scanning Unit (Printer Cover) and make sure all the ink tank lamps are lit. See “Replacing an Ink Tank” on page 108.

If the ink tank lamp is unlit, press the mark on the ink tank firmly until it clicks to fully insert it. Make sure that all packaging material is peeled off the ink tank. See “Replacing Ink Tanks” on page 109.
