Adjust heater and print mode settings
If you see banding in all colors and you have already performed media advance calibration, then you can
try adjusting the heater temperature and print mode settings.
Banding in all colors may be caused by the following factors:
● Small print dot size: heat will cause a smaller dot size. The higher you set the heater temperature, the
smaller the dot size is which results in light banding.
● Ink absorption by the media: if the media you are using is not capable of absorbing the ink as it is
placed, then this can result in dark banding.
To improve ink placement and absorption try the following:
● Set a lower print heater temperature for light banding or a higher temperature for dark banding.
● Change the print mode to reduce the quantity of ink placed on the media for dark banding.
● Change the print mode from bidirectional printing to unidirectional printing for dark banding.
After each change to a setting, try printing the nozzle print pattern to check the image quality.
