Check the estimated ink levels

You can easily check the ink supply level to determine how soon you might need to replace a print cartridge. The ink supply level shows an estimate of the amount of ink remaining in the print cartridges.

TIP: You can also print a self-test report to see if your print cartridges might need to be replaced.

NOTE: The HP All-in-One can only detect the ink levels for genuine HP ink. The ink levels in print cartridges that are refilled or have been used in other devices, might not register accurately.

NOTE: The ink levels shown are an estimate only. Actual ink volumes may vary.

To check the ink levels from the HP Solution Center Software

1.In the HP Solution Center, click Settings, point to Print Settings, and then click Printer Toolbox.

NOTE: You can also open the Printer Toolbox from the Print Properties dialog box. In the Print Properties dialog box, click the Services tab, and then click Service this device.

The Printer Toolbox appears.

2.Click the Estimated Ink Level tab.

The estimated ink levels for the print cartridges appear.
