Routine Maintenance

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.
