It takes about 1 minute to switch a roll of paper. When you switch paper, however, first check out some practical tips on changing the media rolls. I saw the Epson 7000 at the CeBIT computer trade show in Hannover, Germany, in February. It operates with a RIP from BEST, also a German company. Like all Epson printers the quality of the color is really nice.
Problem is that the colors fade, quickly.
At the end of the day compare the Epson print that was out in the full sunlight with the Epson print that was in the dark. The same fading will occur indoors if even ambient light reaches the image. The same fading plagues the Epson 1520, Epson 3000, Epson 5000, Epson 9000, and all desktop Epson printers. They still have their color. I had to remove my Epson prints because they lost their color so quickly.
