My Smart Tank Plus 559 will not print blue or yellow

[Andychay9]

I cannot print blue or yellow.  This may be from lack of use, so I'm thinking something has dried somewhere.

I am contemplating injecting a small amount of white spirit into the print head feeds for the two colors.

Are there any thoughts on this, or is there a better way of sorting this without resorting to buying a new print head?

Hi @Andychay9,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are using white spirit or any other solvent to clean the print head nozzles of your HP Smart Tank Plus 559 is not recommended. These solvents can damage the printer and its components, including the print head. It's essential to use appropriate methods for cleaning printheads to avoid causing further damage.

Here are some safer steps you can take to attempt to resolve the issue:

• Printer Maintenance: Start by running the printer's built-in maintenance/cleaning function. This can often resolve issues related to clogged nozzles. Refer to your printer's manual or HP's website for instructions on how to perform this maintenance.
• Print Head Cleaning: Most printers have a utility or software option for cleaning the print heads. Check your printer's settings or software interface for options related to print head maintenance and cleaning.
• Manual Cleaning: If the built-in cleaning functions don't resolve the issue, you can attempt to manually clean the print heads. However, it's crucial to do this carefully to avoid causing damage. You may need to use distilled water or specialized cleaning solutions recommended by HP. Again, refer to the printer manual or HP's support resources for guidance on how to perform manual cleaning.
• Print Head Replacement: If none of the above steps work, and the print head is still not functioning correctly, you may need to consider replacing the print head. While this can be more costly, it's often the most effective solution for persistent print quality issues.
