Hi @Annieeee,
Welcome to the HP Support Community!
Thanks for reaching out about your query regarding the blinking light error on your printer!
We're thrilled to have the opportunity to assist you and provide a solution.
If your printer's light is blinking, here's a guide to help you out:
Check Cartridge Compatibility: Make sure you’re using the correct HP 315 Ink Tank series ink bottles and that they are genuine HP products. Third-party inks can sometimes cause recognition issues.
Remove and reinsert the cartridges:
Turn off the printer and unplug it from power.
Open the ink tank area and gently remove the cartridges.
Check for any protective plastic seals or tape that might still be attached.
Reinsert them firmly and correctly into their slots.
Close the cover and restart the printer.
