Texture banding results from either unexpected changes in head height during printing, or failure to recalibrate after an intentional head height change. An accurately calibrated engine will produce random, equally distributed concentrations of dots, regardless of the intensity of coverage. A change to the head height without corresponding recalibration of bidirectional accuracy results in overall graininess and banding patterns.
To eliminate or reduce texture banding:
1.Reset the head height through Menu - Service Printer - Cali- brations - Head Height. This returns the head to a known height in the event that it has moved unexpectedly.
2.Confirm the desired head height setting through Menu - Configure Printer - Printer Settings- Head Height.
3.Run AutoBidi and Auto
Swath edge banding occurs at the edges of print swaths, which are the strips of printed output created as the carriage moves across the page.
To eliminate or reduce swath edge banding:
1.Print in HQ mode. See “Selecting a Print Mode” on page
2.If you are printing with two printheads per color, determine which color is causing the banding, and switch the printhead positions in the carriage.
