Hello everyone,

I recently purchased an Epson WF-7840 printer and I am having trouble setting it up. I have followed all the instructions provided in the manual, but I still can't seem to get it working properly. The printer keeps showing error messages and the print quality is not as expected.

I was wondering if anyone else has encountered similar issues with this model or if you have any tips on how to properly set it up and troubleshoot any potential problems. Any help or advice would be greatly appreciated.

Thank you in advance.
