Vertical lines are not aligned or vertical banding appears. How do I align the print head on my printer?

• First make sure you are using the most current version of the printer driver
• Most printers will have a utility function which will give you an option to allign the printer head. Just follow the instructions on the screen.
• Make sure to use the printer's power switch to turn off the printer, otherwise the settings will not be saved
• If you have already tried to align the print head and did not have any success, try turning high speed off in the printer driver settings.
