I refilled the ink for my printer hp310 but ink doesn't flow to the tank in all colors

[BV2019]

Hi everyone! I'm new here and my problem is about refilling my printer ink.  My ink was very low before I left overseas. I'm back five months later and so my printer was idle for five months. I purchased new Hp ink refills and tried to refill but the ink doesn't flow into the ink tank. I remove and inserted again as what I've read in the internet but it still doesn't work. What shall I do?

@BV2019,

Thanks for reaching out to the HP Support community!

Let's try to clean the print head, this may fix the issue.

Clean the printheads using the HP software, and then evaluate the results.

Follow these steps:

1. Open or search for the HP folder in your list of installed software applications, click the folder for your printer, and then click the name of your printer.

   HP Printer Assistant opens.

2. On the HP Printer Assistant window, click Maintain Your Printer.

3. Click the Device Services tab, and then click Clean Ink Cartridges.

   A Print Quality Diagnostic page prints.

   

4. Examine the Print Quality Diagnostic page.

   • If the print quality is acceptable, click Done. You can stop troubleshooting.

   • If the print quality is unacceptable, click Second-level Clean when prompted to continue the next level of cleaning.

   • Note: You can perform the cleaning up to 3 cycles if necessary.
