Adjust Print Quality : Align the Print Head

Align the Print Head
If your printouts become grainy or blurry, or you see dark or light bands across them, you may need to align the print head.
Note:
Dark or light bands may also appear on your prints if your print head nozzles need cleaning.
You can align the print head using the control panel or your software.
