The LX3000 Print Head is printing with Poor Quality, Banding, Streaks, or Missing Colors. Print Hub says I need to change my Print Head. What can I do?

You may need to replace your print head.  The nozzles can wear out over time. 

Your Print Head is warranted for a minimum of 7 changes of any one color of the three colors. If your printhead has been used less than this amount and you are unable to resolve the issue with the cleaning procedure below contact support to receive a replacement.

To determine your warranty status hover your mouse over the ink levels and note the number of changes for each color.



When the software sees that seven tanks of any color have been used, it displays a message that informs you that your print head is now past its warranty and suggests that you replace the print head.  You can keep using it until print quality becomes noticeably inferior and the cleaning procedure below does not fix it.  

Ink is not flowing to the print head from the tanks. It is possible that the nozzles under the print head lid are not sealed completely with the gaskets on the top of the print head.  Typically you would notice this shortly after installing a new print head.  You would be able to print normally until all of the ink in the print head is gone (100 - 200 prints).  If you don't have a good seal on one or more colors the ink would not flow from the tank.  The result would be that color is missing in your print.  To determine if this is the case, examine the tubes leading to the top of the printhead.  If they are clear, that means the ink is not flowing. Once a print head loses all of its ink, it is not possible to recover it.  You will need to purchase a new print head or request one from tech support if it is under warranty.     
 

Note:  It is also possible for the print head to lose its seal after it has been working for part of a tank or several tanks.  If this is the case, you will still see ink residue in the tubes.  If you see ink in all of the tubes, try the cleaning procedure below first before installing a new print head.

Cleaning Procedure:

Important Note: This cleaning procedure can be performed a maximum of 8 times before the print head must be replaced.  See this KB article for an explanation. 

1. Fold a paper towel several times and completely saturate it with warm water or isopropyl alcohol if available. Do not squeeze out excess water from the paper towel.
2. Press the cartridge nozzles to the wet paper towel for 1-5 seconds. 

3. Tap the top of the cartridge firmly with your fingers.

4. Repeat until all three colors are visible on the paper towel.
