Hi. I have a rental business in Korea.
Thanks to our chipless solution, we are renting Epson printers and multifunction devices. Thank you.
The reason for posting on the bulletin board is that some users have complained to write.
Is there a difference in color by printer model? When I test printing using the same paper and ink, the C5710 has become darker after the latest firmware update, but the C5790, C5290, and C5210 are still faded. Epson genuine firmware all prints in the same color, but other models except for the C5710, the color is blurred and users complain. When can it be improved?
