The CX4800 takes Epson Durabrite /Ultra/ Ink, which is even stickier 
and faster drying than the original series of Durabrite inks. I don't 
remember the specific numbers (Epsons have really insane numbering 
schemes, something like T0x00xx), but it's the one with the 
fanback Chair design on the front of the box.

As I said before, most Epsons take the exact same /shape/ of 
cartridge, the only differences are the chips which let the printer 
know which # and the volume left inside. I don't know how well the 
R-series printer would modify to allow thicker boards through. The 
tray will take CDs, but it often rejects printing if not aligned 
perfectly, it has special ultraviolet sensitive white patches on the 
tray so that the printer can 'see' where the CD will be. Even the 
slightest misalignment will cause it to reject the printing and you 
have to re-load the tray over and over again. If you are going to 
modify one of these, I would be careful to make sure that the 
printhead won't ram into whatever you're trying to put into it. I am 
not sure if the 'standard' size Epson cartridge also works for the 
2200, that one's an older model, I believe.
