maintenance operations such as Print Head Cleaning.
Print the Nozzle Check Pattern to determine whether the ink ejects properly from the print head
nozzles.
Refer to When Printing Becomes Faint or Colors Are Incorrect
Print Head Cleaning, and Print Head Deep Cleaning.
If the Nozzle Check Pattern is not printed correctly:
Check to see if a particular color's ink tank is not empty.
If the Nozzle Check Pattern is not printed correctly though ink is sufficient, perform the Print Head
Cleaning and try printing the Nozzle Check Pattern again.
If the problem is not resolved after performing the Print Head Cleaning twice:
Perform the Print Head Deep Cleaning.
