Knowing how to check printer ink levels helps you avoid running out in the middle of a job. You can check from the printer, your computer or your phone. The readings are estimates.

On the printer
Many printers show ink or toner status on the display or in a Settings or Supplies menu.
On Windows
Open Settings, go to Printers and Scanners, select the printer and open its preferences or the manufacturer’s software to see ink levels.
On Mac
Open System Settings, go to Printers and Scanners, select the printer and look for Supply Levels in Options and Supplies.
In the manufacturer’s app
The maker’s phone or desktop app usually shows ink levels and can reorder supplies.
Ink levels are estimates
Printers estimate ink from usage, so the number can be off. For tank printers, you can also look at the tank window.

How Accurate Are Ink Levels?
Most printers estimate ink from the number of dots they print and, in some models, from a sensor. The estimate can be wrong, especially with third-party or refilled cartridges. Treat the number as a guide rather than an exact reading.
What to Do When It Says Low
A low ink warning is an early alert. You can often keep printing until quality drops, but keep a spare cartridge ready. If your printer refuses to print on a low or empty cartridge, replace it.
Tank Printers
Ink tank printers usually have a transparent window or marked tank so you can see the ink level directly. Refill before a tank runs completely empty, so air does not enter the system. See how to refill an ink tank printer.
Why Ink Goes Down Without Printing
Inkjets use a small amount of ink for cleaning cycles and startup maintenance, so levels can fall even if you print little. Printing something regularly helps keep the printhead healthy.
Order the Right Cartridge
Check the cartridge number in your manual or on the old cartridge, then match it exactly. See best ink for printers.
