How to Download and Install the Adjustment Program

Step 1: Download the Program

The Epson EP-904A Adjustment Program is not freely available on Epson’s official website. However, it can be found on third-party service websites or obtained from Epson service centers. Ensure that you download it from a reputable source to avoid malware or corrupted files.

Step 2: Extract and Run the Program

Once downloaded, extract the compressed file using WinRAR or a similar tool. Open the folder and locate the executable file (usually named Adjprog.exe). Run the file as an administrator.

Step 3: Disable Antivirus and Firewall

Some antivirus programs may flag the adjustment program as a threat. Before running the software, temporarily disable your antivirus and firewall to prevent any interference.

Step 4: Connect Your Printer

Ensure your Epson EP-904A is properly connected to your computer via USB. The program may not detect the printer if it is connected wirelessly.
