HP SmartTank Ink level issues

[ten1119]

Need help due to my Ink level of SmartTank 615. I still have a half-tank of CYAN, MAGENTA, YELLOW, BLACK Ink. I can't do a print task by "Indicated tanks do not have enough ink..." of CYAN tank only. Help me ASAP

Hi @ten1119,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand your HP SmartTank 615 is showing an ink level error even though the tanks are half full, and it is blocking printing due to the Cyan tank. Let’s go through a few steps to check what could be causing this.

Check the physical ink level and ink type
Open the ink tank lid and visually confirm the Cyan ink level is above the minimum line.
Make sure only genuine HP ink and the correct ink color was used in each tank.

Remove air bubbles from the ink tubes
Turn the printer off and gently tap the Cyan ink tank from the side.
Air bubbles in the ink line can cause false “not enough ink” messages.

Run Ink System Maintenance
Open HP Smart > Printer Settings > Advanced Settings or Tools.
Run “Ink System Maintenance” once to re-prime the ink flow.

Perform a printer power reset
Turn the printer on and disconnect the power cord from the rear of the printer.
Unplug it from the wall, wait 60 seconds, then reconnect and power it back on.

Refill a small amount of Cyan ink (important)
Add a small quantity of Cyan ink even if the tank looks half full.
SmartTank printers sometimes require ink to be topped up to reset the ink sensor logic.

Update printer firmware
Open HP Smart and check for printer updates.
Outdated firmware can cause incorrect ink level detection.

Reset ink level monitoring
Turn the printer off, unplug it, and leave it disconnected for 10 minutes.
Reconnect and turn it on to allow the printer to reinitialize ink level sensors.

Print a diagnostic or test page
From the printer control panel or HP Smart app, print a test or quality report.
This confirms whether the Cyan ink system is now recognized correctly.

I hope this helps.
