How can I improve print quality if it's poor?

You can improve print quality by running the printer's head cleaning utility, ensuring the cartridge is properly installed, and checking that the ink level is not critically low.

Troubleshooting

Cartridge not recognized by printer

Ensure the cartridge is correctly installed and all protective tapes/clips are removed. Try reseating the cartridge. Clean the electrical contacts on the cartridge and printer with a dry, lint-free cloth.

Poor print quality (streaks, missing text)

Run the printer's built-in head cleaning utility. Check if the ink cartridge is low or empty. Ensure the correct paper type is selected in the print settings.

Ink smudging on paper

Allow printed pages to dry completely before handling. Ensure you are using the correct paper type for inkjet printing. Check that the printer settings are appropriate for the paper being used.

Low ink warnings despite recent replacement

Verify you have installed the correct HP 21 black cartridge. Printer ink level estimates can sometimes be inaccurate; try printing a few pages to confirm actual ink status. Ensure the protective tape was fully removed from the vent opening.
