Everything has changed with these printers over the last few years - computers, operating systems, cables, different versions of Epson software.
I was hoping it was some basic flaw in how I was doing it. Like "you have to open the program before you switch the tray to the CD position" (or the reverse). Or "you have to wait X number of seconds after printing the first disc before inserting subsequent discs". I just don't know and at this point, I no longer care.
Yesterday, I changed two color cartridges, both genuine Epson from a retail package and the printer would not recognize one of them (cyan) as an Epson cartridge! Tried all the tricks and fixes I could find on the web, but no luck. I ended up driving a 20 mile round trip in a snowstorm to buy another cyan cartridge which, thankfully, worked.
It was strange in that the Epson Status Monitor had a big red X on the first cartridge indicating it couldn't be recognized and that maybe I should "use a genuine Epson cartridge next time", but clicking on the information button showed that particular cartridge WAS recognized as "EPSON genuine CYAN 78". In other words, it couldn't recognize it in one case, but could in the other.
Does anyone not play games with their printers, like HP with their half-full "starter cartridges" or Epson with their chip-in-the-cartridge that used to tell you it's empty when it wasn't? I'm about to try a Canon PIXMA iP4920 for disc printing, since they're finally making printers for the US market with disc printing capabilities. I've never been very impressed with Canon in the past, but maybe I'll give them another try.
I really hate to change brands because the EPSON works fine for all other printing and does a great job of disc printing (when it's not in a "fault condition"), the PrintCD software is very easy to use and serves my purposes well, but I'm getting sick of some of the quirks in these Epsons.
