How to fix bad printing quality for HP OfficeJet Pro 8020 8022 8035

Have you ever printed on your HP 910 printhead, only to have the text or images come out blurry? Perhaps your print area suddenly stopped, well short of finishing the design you were trying to print. This can be frustrating, and you may think that you’ve run out of ink. But if you just changed or refilled your cartridges not long ago, there is another explanation.

Your printer may produce blurry or cut-off results if you have a printhead clog. Fortunately, it’s not too difficult to fix. This post will walk you through five simple steps to unclog the printhead and get your printer running smoothly again.

Though the printer’s built-in cleaning function may not be enough to fully clean the printhead, you can clean it even better by hand. To do this, you can purchase a printhead cleaning kit, complete with a pair of pre-assembled FlushTip900 adapters, through BCH Technologies.

Step 1

Kill your printer’s power by unplugging it, and remove all cartridges from the device. Now make a sort of “diaper” for the printer, folding a paper towel in half, and then in thirds. Tuck it underneath the printhead. This will contain the cleaning solution that you’ll be using to clean off the printhead and will contain the mess.

Step 2

Fill the syringe with 10 ml of the cleaning solution from your printhead cleaning kit. Slowly and gently push down the FlushTip900 plunger and inject the cleaning solution into the printhead. Be sure to keep pressure applied evenly to the tip of the syringe hose, which will help you avoid leaking as you push the cleaning fluid into the printhead.

When using the FlushTip900, you will note that there’s a piece of black rubber washer on the printhead, sandwiched between your syringe tip and the base of the printhead entry point. This will help you stop anything from leaking out as you inject the cleaning solution. This is why it’s important to apply even pressure as you fill the printhead, or the cleaner could spray everywhere.

Step 3

Switch to the smaller tipped syringe and repeat the previous step with the rest of the colors. Carefully inject cleaning solution into each printhead while applying even pressure to the tip to keep it in place. Remember that your goal is to inject the red cleaning solution into the printheads—you’re not trying to flush everything out of the system or force the fluid out the bottom.

Step 4

Now that the printhead is filled with the cleaning solution, you can reinsert the cartridges and close the printer cover. Leave it to soak overnight, or for at least 12 hours. Don’t forget to take the paper towel “diaper” out from beneath the printhead before plugging the printer back in. Then, start the printer up and prepare for the final cleaning step that will restore your printer’s function.

Step 5

Use the printer’s built-in printhead cleaning process to suck out the cleaning solution. Do a test run. If the printed sheet still comes out wrong—let’s say, perhaps it has a white stripe running through the center—you will need to perform a second cleaning. Hit the “clean again” button on your printer to repeat the process until you achieve a perfectly printed page. Make sure all the colors are working properly, not just one or two.

After the cleaning, you may see the blank strip move its position in the color blocks. If the white stripe moves from the center to near the edge, it’s a sign you need to refill the ink in that color. The printhead is now printing evenly, but it’s running out of ink near the end, leaving the blank spot at the edge of the test print color block. Simply refill or replace that color cartridge and run the test print again.

Enjoy Your Printer

And that’s it! Your printheads are now clean and good as new again. As long as you have enough ink in the cartridges, it should print your pages without errors.
