When the Epson WF-7620 print head cleaning not working you should know that there is a manual way that you can achieve the same result.
However, in this guide, we’ll first attempt to solve the problem with the software print head cleaning and then learn how to do it manually.
When the print head cleaning is not working on Epson WF 7620, users need to perform a power cycle on the printer and refill the black ink tank. The next step is to position the printer on a flat surface and make sure that the paper is not out of place.
Knowing this, let’s proceed with learning more about the process and later how to fix it:
To avoid spending your printer’s resources on a pointless print head cleaning, there’s a quick test that you can carry out.
In the menu where you put on the print head cleaning process, there’s also a button that makes the printer write on paper to let you know if the printing is alright.
To trigger a print test, go to the “Maintenance” tab in your Epson WF-7620 printer settings and click on the first option.
The test will cause the printer to write a couple of lines with all available colors. If some of the lines are not fully colored, not finished, or missing (blank spots), your printer is not printing correctly.
If your Epson printer isn’t cleaning properly and the print head cleaning isn’t working!
To solve the problem with the print head cleaning with the Epson WF 7620, we’re going to undertake a specified solution list, dedicated to this model.
Let’s jump right in!
A hard reboot on your Epson printer may get things going in the right direction.
If there’s a power failure (insufficient electricity supply), some of the features may become unavailable on your printer, such as the print head cleaning.
To hard reboot your Epson printer, follow these instructions:
- Shut down the device using the power button.
- Disconnect the power adapter from the power source.
- Wait for 5 minutes while the printer discharges completely.
- Re-attach the power adapter to the source.
- Turn on your printer.
- Try running the print head cleaning feature.
Note: Make sure to keep your printer unplugged for at least 5 minutes or the hard reboot won’t work.
Your Epson printer and all printers in general, require ink for print head cleaning.
If the ink tank is empty, your printer won’t have the resources to clean its print head from leftover ink or any other debris that’s preventing good printing.
To perform a print head cleaning, the black ink tank bottle must be at least half full.
Here’s how to refill the black ink:
- Get a bottle with the appropriate ink.
- Put away the ink tank bottle’s latch.
- Eject the black ink tank.
- Fill the tank with black ink.
- Reinsert the tank.
- Wait for your printer to consume ink.
- Try turning on the print head cleaning.
Alert: Make sure that you don’t overfill the ink. There must be at least 3 centimeters on top of the bottle, or this may clog the print head even further.
If your printer’s papers are inserted incorrectly or are sitting in an unnatural position, the device won’t be able to grab a piece to complete the print head cleaning.
Your printer must always have an access to the papers inserted in the compartment or its features won’t work.
On the WF 7620 model of Epson printer, there are two markings in the paper bed in-between which, you must position the paper.
Just make sure that the patch of papers is sitting in a completely natural position and is laying down on the pad.
Note: Check if any of the papers in the bottom got wrinkled due to failed print head cleaning attempts. This may prevent the printer from grabbing any papers.
Your printer’s positioning is essential to how the device work.
Since print head cleaning is a physical task that the printer must undergo with its parts and components, the unnatural position of the device’s hardware may prevent it.
In regard to positioning, there is one more important factor you must take note of.
It is whether the printer is staying on a flat straightforward surface or is sitting diagonally.
It’s really unhealthy for printers to leave them sitting diagonally since this can mess up the paper’s position and cause bad printing.
Before you retry the print head cleaning process, position the printer on a flat surface!
Note: If you have to, relocate your printer elsewhere, along with the power adapter.
Power issues can also cause the Epson WF-7620 print head cleaning not working
problem. Luckily, there are a couple of easy solutions you can undertake to resolve your device’s power problems.
Since you’ve already tried the power cycle, here’s what else you can do:
- Plug to a different power source – relocate your printer and connect it to an alternative power source.
- Disconnect from power strips or dividers – make sure that your Epson printer is not connected to a power strip or a divider.
- Discharge power adapter – disconnect the power adapter from both ends for 60 seconds and test.
Note: Make sure to test your printer’s functionality after applying each of the bullets!
If nothing worked so far, you should reset your Epson printer to factory defaults.
If the problem with your device is software related, this will surely resolve the problem and make your printer eligible for print head cleaning.
To reset your Epson printer to factory defaults follow these instructions:
- Turn OFF your printer with the power button.
- Locate the reset button on the back of the device (near the Ethernet port).
- Press and hold the reset button.
- Turn on the printer while still holding the reset button.
- Wait until the digital panel displays a successful reset.
Alert: If you let go of the reset button before turning on your printer, the reset will fail.
If you couldn’t trigger a print head cleaning through your Epson WF-7620 software, you can do it manually.
Cleaning the print head manually requires a little bit of attention, but in this guide, we made it easy and simple as long as you follow our instructions.
Here’s how to manually clean the print head and the nozzles of the print head:
- Turn on your printer.
- Enable document printing.
- While the printer is working actively, disconnect its power adapter.
- Remove the cartridges from the slot (they are easily slidable now).
- Grab a plastic tube that fits the slot of the print head.
- Grab a syringe and fill it with a mix of distilled water and printer refresh liquid.
- Insert the syringe into the tube that has connected with the print head.
- Empty up the syringe inside the tube.
- Re-insert the cartridges.
- Your printer’s print head should now be clean!
Note: Make sure that you use a licensed refresh liquid for your printer, because soap or other basic cleaning material may impact the internal hardware.
Hence, the Epson WF 7620 won’t be able to perform a print head cleaning when the ink tank is empty or when it’s not able to grab the paper. To solve the problem users need to inspect ALL components involved and, if necessary, perform a factory reset.
Now that we know why the Epson WF-7620 print head cleaning not working and how to solve the problem, the process should no longer fail.
In case the issue is persistent, regardless of what you attempt, the best next step is to use the warranty or bring the printer for servicing.
