There is a white line appearing vertically when I print. How can I get it to go away?
Print quality issues often cause dirty or worn-out printheads or dirty platen. Regular maintenance of cleaning and replacing printheads and platen ensures the best print results.
Printheads must be maintained regularly through cleaning. There are several ways to clean your printer's printhead, including cleaning pens and cleaning swabs.
