Horizontal lines or banding can be caused by one of the following:

  • Incorrect settings
  • Paper feed adjustments
  • Missing or blocked nozzles
  • Dirty capping station
  • Dirty vertical encoder

Missing Nozzles

The most common cause of lines on prints are missing nozzles. To confirm this, you can print a nozzle check from within the printer menu > Printer Features> List/test Print> Nozzle Check pattern. Missing nozzles will be displayed as missing/blank dash on the gridded pattern. Please refer to the Missing nozzles section for further assistance.

Incorrect settings

To avoid any settings issues we recommend printing using the Sawgrass Print Manager software If you are printing from a graphic software please see our configuration guide for further assistance regarding this.

Paper feed adjustments

Another cause of horizontal banding could be because the paper feed adjustment are no longer correct and need to be aligned. This is a simple adjustment that can be access through the printer menu > Printer Features> List/test Print > Adjust Paper Feed.

Dirty capping station

Signs of a dirty capping station are thick dark or light bands, usually in a specific colour.  To rectify this, we would recommend soaking the filter part of the capping station with some hot distilled water for 10-15 minutes followed by a head flush. You may need to soak it multiple times for it to have the desired effect. When clean, the solution should be absorbed by the filter within a matter of seconds. Once it is clean, we recommend you perform a head flush.


If despite performing the above, your prints are still showing lines, please submit a ticket to our support team who will be able to assist you further.
