							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.
●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 banding.
To improve ink placement and absorption try the following:
●Set a lower print heater temperature.
●Change the print mode to reduce the quantity of ink placed on the media.
●Change the print mode from bidirectional printing to unidirectional printing.
After each change to a setting, try printing the IQ print to check the image quality.
To change the heater temperature and print mode settings:
1.Press the ONLINE key and select the MEDIA REG menu with the ▼ key.
2.Select PRINT HEATER T in the MEDIA REG menu with the ▲ and ▼ keys.
Parameters: 15 °C to 55 °C, or ** to turn the heater off.
