How to Change Ink in Epson WF-7840

Changing the ink in an Epson WF-7840 printer involves replacing the old ink cartridges with new ones. Below, you will find step-by-step instructions to guide you through the process.

Summary

To change the ink cartridges in your Epson WF-7840, ensure the printer is on, replace the cartridges when the ink level is low, and follow the steps below for a proper replacement.

Steps to Replace Ink Cartridges

1. Turn on Your Printer

   • Ensure that your printer is powered on.

2. Open the Scanner Unit

   • Lift the scanner unit. It is important to do this carefully to avoid any damage. The printer must be on because lifting the scanner unit while the printer is off could damage it.

3. Wait for the Cartridge Holder

   • After you open the scanner unit, wait for the ink cartridge holder to move to the replacement position. The printer will make some noise as the cartridge holder moves into the correct position.

4. Remove the Old Cartridge

   • Before you proceed, identify which cartridge needs replacement. The LCD panel on the printer can indicate which cartridges are low on ink or empty.
   • Push the tab on the cartridge towards the printer to release it, and then lift the cartridge out of the holder.

5. Prepare the New Cartridge

   • Take your new cartridge and shake it gently four or five times while it is still in the package.
   • Remove the cartridge from the package, being careful not to touch the green chip on the cartridge.
   • Remove the yellow tape from the bottom of the cartridge. Avoid touching the ink nozzles or the green chip.

6. Install the New Cartridge

   • Insert the new cartridge into the holder and push it down until it clicks into place.

7. Close the Scanner Unit

   • Lower the scanner unit slowly and ensure it is completely closed.

8. Check the Cartridge Recognition

   • After replacing the cartridges and closing the scanner unit, the printer will take a few moments to recognize the new cartridge and prime the ink delivery system. Follow any instructions on the printer’s display.

9. Print a Test Page

   • Once the printer recognizes the cartridges, it is a good idea to print a test page to ensure that the new cartridges are working properly.

Additional Tips

• Always use Epson genuine cartridges for reliability and quality.
• Keep new cartridges ready as ink levels can run low quickly depending on usage.
• Dispose of old cartridges responsibly, preferably by recycling.

Following these steps should help you successfully change the ink in your Epson WF-7840 printer without any issues.
