Hi Degger,
• Do you receive any error message while copy system file?
0x000000c1 error occurs if the printer driver that is installed on the computer is corrupted.
You will need to visit the Epson website manually download and install the latest printer drivers and check if it works.
You may use the below link to download and install the printer drivers depending on the version of Windows installed on the computer. http://www.epson.com/cgi-bin/Store/support/supDetail.jsp?oid=130786&prodoid=63084540&infoType=Downloads&platform=Windows
If you are using Windows XP refer the below Microsoft article.

If you are getting error while copying the files from the recovery partition, you will need to contact the computer manufacturer as recovery partition is created by them.
Hope this helps!
