Step 1: Check all your connections.
Check the hardware for any loose connections. Check if the main power cable from the power source is properly connected with the printer. Also, check if the wire from the printer is properly connected with the computer.
Remove all wires and clean all the wires to get rid of any dust or particles which might hinder the connection.
If you have a wireless printer, make sure that all the routers and wireless connections are proper.
If you have a network printer, there could be a problem with the network connections. Call your system administrator to ensure that all the wirings are properly inserted.
Once you have made sure that all your wirings are correct, restart your printer. In most cases, this should fix problems right away. If not, follow the next step.
Step 2: Reinstall/Update the Driver.
You might have updated your system to a newer version, or the older printer driver might not be useful right now. So, to know how to fix Epson printer error state, you will need to uninstall and reinstall the driver. You can use the disc which came with the printer to install the driver.
If reinstalling the driver did not fix it, you can try updating the driver. You can go to the Epson’s official website to check for the latest available drivers. Search the website using the model number of your printer. Download the driver that is designed for your printer and install it on your system.
Step 3: Windows Troubleshooter.
Using the windows troubleshooter is the last option that you have when it comes to the Epson printer error state. Go to the Device Manager in your system and locate the printer option. Expand the printer option and search for your printer.
Right-click on your printer on your PC and click on Troubleshoot. This will open up the Troubleshooter which will look for possible solutions to the printer error state. The windows Troubleshooter is not a very reliable option, but it is worth a try. If none of the above options have worked for you, Windows Troubleshooter will most probably do the trick.
