Yes, every printer is sold with factory-installed tanks (starter cartridges). These typically hold less ink or toner than standard cartridges sold separately. They are included so you can start printing right away without having to buy additional supplies.

In practice, this means that once you take the printer out of the box, you can start printing right away, but with heavy use, you’ll use up the starter cartridge faster and will need a full-size one sooner.

The fastest way to perform a printhead test (nozzle check) on an inkjet printer is from your computer or the printer’s control panel.

How do you run the test from your computer?
1. Turn on the printer and make sure there is plain paper in the paper tray.
2. On your computer, open Control Panel or Settings, then go to the Devices and Printers (or Printers and Scanners)
section 3. Click your printer’s icon and select Printer Properties or Printing Preferences.
4. In the panel, find the Test Print or Print Test Page option.
6. Click Print to have the printer generate a test pattern.

How do I run a printhead test from the printer?
1. Make sure plain paper is loaded in the paper tray.
2. On the touchscreen or using the buttons on the printer’s control panel, go to Settings.
3. Find Maintenance or Tools in the menu.
4. Select Nozzle Test or Nozzle Check and confirm the print.

How to evaluate the test results:

Correct printout—the printout is clear for every color; no lines, gaps, or missing areas are visible.

Clogged nozzles—the test print shows gaps, lines, and missing sections. This means that some nozzles are dried out or have air trapped inside them. In this case, run the Printhead Cleaning function.

It’s a good idea to clean the print head when print quality has noticeably deteriorated, even though the cartridges have enough ink. The most common signs are:

✓ white, horizontal stripes on the printout,

✓ broken or faint lines in the text,

✓ missing parts of letters or graphics,

✓ one color missing,

✓ incorrect, distorted, or overly bright colors,

✓ blank or nearly blank pages even though the ink cartridges are full.

This problem often occurs after a long break in printing, because the ink may have partially dried in the print head nozzles.
