Printing Maintenance

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;
Open the 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. Replace the ink tank. Refer to “
Replacing an Ink Tank” in the
Direct Printing Guide .
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 cover and make sure all the ink tank
lamps are lit. Refer to “Replacing an Ink Tank
Replacing an Ink Tank Replacing an Ink Tank Replacing an Ink Tank” in the Direct Printing Guide .
If the ink tank lamp 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. Refer to
“Replacing an Ink Tank
Replacing an Ink Tank Replacing an Ink Tank Replacing an Ink Tank” in the Direct Printing Guide .
Increase the Print Quality setting in the printer driver settings.
