How to Clean Printer Heads Using Household Products Canon, HP, Epson

Working in Information Technology I am often asked to fix printers that are blurry, blotchy, and have substandard printer results. Often it is the result of running out of ink and letting the print head dry out.

When a printer is left without ink the print heads will block. Sometimes a deep cleaning with new ink will fix the problem but if it doesn’t then a manual print head clean will be required.

In this post, I will show you how to make your own printer head cleaning solution. As well as how to manually clean and flush the printer head on all types of ink printers. This procedure will work for all brands of inkjet printers such as Canon, HP, and Epson.

Now you can buy the ready-made prink head cleaning kit or you can make your own using some household products such as Windex and Rubbing Alcohol. Also known as Isopropyl Alcohol.

I like to make my own homemade print head cleaning solution out of 8-parts Windex to 2-parts rubbing alcohol. Windex is used for cleaning windows and rubbing alcohol is also known as Isopropyl Alcohol. These are items I have on hand to quickly and easily make up the solution when required.

They will store forever in a sealed bottle ready for the next time you need the household printhead cleaning solution.

Items Needed to clean printer heads.

  • Print head cleaning solution. Either store-bought or DIY print head ingredients. (8-parts Windex to 2-parts rubbing alcohol)
  • Empty Syringe.
  • Small flexible tubing 1/4 inch or to suit syringe nozzle.
  • Paper towel.
  • Glad wrap.
  • Extra paper and ink for deep cleaning and printer testing.

Start by turning on your Canon printer and removing all the ink cartridges. I like to wrap them in plastic Glad wrap to keep them from drying out or leaking.

Turn off the printer and remove the power plug for safety. You will now see the silver print head filters. These are what we will be cleaning as they can block up with dried ink.

Put some printer cleaning solution in a syringe and attach the small tubing to the end.

Fold up the paper towel a few times and place it under the Canon printer head. You may need to slide the printer head from side to side to get the paper towel under the printer head. I had to experiment a little to get the correct width and height of the paper towel so that it fits under the printer head.

The paper towel is to catch the free-flowing dried ink from out of the print head filter once we start flushing. You can also use printer paper folded over a few times. But paper towel works the best.

I like to clean each Canon print head filter one at a time rather than only the one that has the blockage. Squeeze some cleaning solution onto the ink silver filter. The fluid may get sucked in straight away or it may bubble on the top.

If it does bubble on the top then you will have to wait 10 minutes to see if it will filter down and clear the build-up blockage.

If it is flowing correctly you will start to see some colored ink collecting onto the paper towel underneath the print head. Change the paper towel under the print head once it begins to get full of old ink and cleaning solution.

After a few print head cleaning flushes, I like to leave the print head to dry out any remaining cleaning solution. One hour should be enough to completely drain any remaining solution.

What a mess this is why you need to use paper towel under the canon print head.

Remove the paper towels and replace the printer ink back into the correct placeholders.

Do a deep head clean using the Canon software to flush out any remaining solution and fill the filters with new ink. This should now give you perfect printing results.

Sometimes warming up the cleaning solution to around 45 deg celsius will aid in resolving the stubborn printhead clog.

I like to warm up the print head cleaning solution up in a bowl of hot water. Once it is up to the temperature you can put it in the syringe and squeeze it into the print head ink intake. Remember to place a paper towel under the print head to capture the excess solution.

Can I use methylated spirits to clean printer heads?

Yes, I have used methylated spirits to clean printer heads in the past. It works well but be aware that as it is not as pure as Isopropyl Alcohol it can leave behind some fine residue that will need flushing before using the printer.

Once you have cleaned the print head with 8 parts methylated spirits and 2 parts Windex you will need to do a deep clean with the printer ink to flush out any impurities. This is done via printer software.

Conclusion

I have cleaned hundreds of printheads over the last few years and there has been a few stubborn printheads. The DIY 8-parts Windex to 2-parts rubbing alcohol is the best cleaning solution around.
