I have an epson 7880, and I am getting ready to purchase my first large format replacement ink cartridge. Is there any reason that I can't run some cartridges with 110ml and others with 220ml? I figured for the light colors that are used at the fastest rate, I would get large cartridges (yellow, light cyan, light magenta, light light black). Actually, because of the cost savings, I may just convert all to 220ml, but I don't want to have to replace all at once. It seems like it would be crazy to not be able to do them together, but sometimes these things don't seem logical.
(Who would have thought you would have to change black cartridges to go back and forth between matte and glossy?)
I recall reading somewhere that some of the large format printers require the 220ml cartridges to stick out of the front of the machine. I don't think the 7880 is like that. Are the outside dimensions of the cartridge identical between 220? and 110?
