Adjust Print Quality : Align the Print Head

Align the Print Head
If your printouts become grainy or blurry, you notice misalignment of vertical lines, or you see dark or light horizontal bands, you may need to align the print head.
Note:
Banding may also occur if your print head nozzles need cleaning.
