Print4All 0 Report post Posted January 30, 2019 I've been trying to use the "Coloimetric Calibration Tool" that's part of the Epson 3800 Adjustment Program, but I cant get it to work. It appears there is missing software (files/folders) in the program. I also noticed missing software that allows the "Firmware update Tool" to function. Has anyone else noticed this?
