HP 305 not printing in black: causes, solutions, and when to replace the cartridge

If your HP printer uses HP 305 or HP 305XL cartridges and suddenly stops printing in black, prints very lightly, or produces blank pages, it doesn't always mean the cartridge is broken. In many cases, the problem can be solved by cleaning it, performing a quick check, or reinstalling the cartridge correctly.

Why is my HP 305 not printing in black?

HP 305 cartridges have the printhead built into the cartridge itself. This has one advantage: if the printhead dries out or becomes clogged, the problem can often be solved by replacing the cartridge. But before buying a new one, it's worth checking several common causes.

Most common causes

1. Check if the HP 305 cartridge has ink

First, check the ink level using the HP Smart app or the printer's control panel. If the level appears low or empty, the black cartridge is probably empty.

Even so, sometimes the printer may show remaining ink even though the cartridge no longer prints well. This is because the ink level is usually an estimate, not an exact measurement.

2. Remove and reinsert the cartridge

Open the printer cover, wait for the carriage to move into the cartridge replacement position, and remove the HP 305 black cartridge. Then reinsert it until it clicks into place.

3. Clean the cartridge contacts

If the printer does not detect the cartridge properly or prints poorly, there may be dirt on the metal contacts.

Do it like this:

1. Turn off the printer.
2. Remove the black cartridge.
3. Gently clean the contacts with a dry, lint-free cloth.
4. Do not touch the nozzle area with your fingers.
5. Reinsert the cartridge.
6. Turn on the printer and test it again.

4. Run a printhead cleaning

You can run a printhead cleaning from the HP Smart app or the printer software. This option forces ink through the nozzles and can restore a partially dried-out cartridge.

After cleaning, print a test page. If it improves but still prints poorly, you can repeat the process a second time.

5. Check if you haven't printed in a while

If the printer has not been used for weeks or months, it is quite common for the black cartridge to dry out. In ink cartridges, lack of use can cause the nozzles to become clogged.

To prevent this, it is best to print a page every 2 or 3 weeks, even if it is just a simple page with black text.

6. Try printing in black only

Sometimes it seems like black is failing, but the problem is actually in the print settings. Check that draft mode, incorrect grayscale, or an extreme ink-saving setting is not enabled.

Try printing a simple document with black text from another program or your mobile phone.

7. Restart the printer

Turn off the printer, disconnect it from the power supply for 60 seconds, and turn it back on. Then reinsert the cartridge and perform a test.

This step may seem basic, but it often eliminates temporary recognition or communication errors between the cartridge and the printer.

When should I replace the HP 305 black cartridge?

You should replace it if any of the following occur:

• The printer shows the ink level is empty.
• It still won't print after cleaning the printheads.
• It prints broken lines or very light text.
• The cartridge has been open and unused for a long time.
• The test page comes out without black ink.
• You have tried cleaning the contacts and restarting without success.

HP 305 or HP 305XL: which one should I buy?

The main difference is how long they last. The HP 305XL cartridge has a higher capacity than the standard HP 305, so it is usually a better choice if you print fairly often.

Frequently asked questions about HP 305

Why does my HP printer print in color but not in black?

This usually happens because the black cartridge is empty, dried out, or has clogged nozzles. It can also be due to improper installation or dirty contacts.

Can I print if the black cartridge is not working?

On some models, you can print using only the color cartridge, but this is not ideal. The quality will be worse, and you will use more color ink.

Can a dried-out HP 305 cartridge be restored?

Sometimes, if the drying is minor. You can try a printhead cleaning from HP Smart. If it does not improve after several attempts, it is best to replace it.

Can a compatible HP 305 cartridge cause problems?

A quality compatible cartridge should work correctly. If the printer does not recognize it, check that it is compatible with your model, clean the contacts, and restart the printer.

Which printers use HP 305?

The HP 305 is used in many HP DeskJet, HP Envy, and HP DeskJet Plus printers. Before buying, always check compatibility with your exact model.

Is it better to buy HP 305XL?

Yes, if you print regularly. The HP 305XL offers higher capacity and is usually more cost-effective than the standard cartridge.

Conclusion

If your HP 305 is not printing in black, start with the basics: check the ink level, reinsert the cartridge, clean the contacts, and run a printhead cleaning. If it still won't print after all that, the cartridge is probably dried out or empty.

In that case, replacing the HP 305 or HP 305XL black cartridge is usually the quickest solution.
