Unwanted horizontal white lines or stripes appear
Problems with print quality, especially horizontal white lines in your
document, may mean a nozzle on the print head is clogged or your ink
cartridge is running out of ink. There are two ways you can clear up the
problem.
m Cleaning the print head is the faster method. It forces a nozzle cleaning as
part of a print job. In other words, you can tell the printer to clean the print
head before it starts printing the next document.
m Printing a test page also cleans the print head. It gives you a test pattern
you can evaluate, but it takes a bit longer.
IMPORTANT
Cleaning the print head consumes a small amount of ink. If you
repeat the procedure unnecessarily, you reduce the life of your cartridge.
Explanations of both procedures follow.
