If print quality has not improved after repeating this procedure about four times, turn the product
off and wait for at least six hours. Then run the nozzle check again and repeat the head cleaning
if necessary.

damaged and may need to be replaced.

Aligning the Print Head
If you notice a misalignment of vertical lines or horizontal banding, you may be able to
solve this problem by using the print head alignment utility in your printer driver.
Note:
Disc thickness may vary, depending on their manufacturer. Using discs with various thicknesses
may result in misalignment of the print head. Use the print head alignment utility to check and adjust
the print head alignment. It is recommended to use the same product and type of discs when
publishing several discs.
