Black and Yello ink is not flowing into the printer's hose

[EricMaCC]

I received an HP Ink Tank 315 as a gift from a friend, and after not using it for a while I noticed that the ink was not flowing into the printer's hoses. As I continue to print, the blacks are no longer printing and the yellows are getting less and less clean because I believe the ink in the printhead is decreasing. But the ink in the ink tank doesn't seem to be reduced. How to get ink to flow into the print head?

Hi @EricMaCC,

Welcome to the HP Support Community. 

I'd like to help!

Update Firmware

Perform the following tasks in the order given. Use the printer after each task to see if the issue is resolved.

Check ink levels and fill the tanks

Low ink levels can impact print quality. Refill any tanks that are low on ink.

On the ink tank windows, find the maximum and minimum fill lines.

NOTE:

Purchase replacement cartridges and other supplies from the HP Store or local retailers.

Ink tank fill lines

1: Maximum fill line

2: Minimum fill line

Fill any tanks that are at or near the minimum fill line.

NOTE:

Print quality can be affected if an ink tank falls below the minimum fill line. Overfilling the ink tanks can cause ink leakage.

Order new ink bottles from the HP Store or your local office supply store that carries HP products.
