Next in the chain are the ink tubes and primer. In either case, the basic functionality is that it's a holder for the ink. Newer tanks have a small PCB with a flash chip on it, so the printer can tell if a tank is new or used, or if it's an Epson brand cartridge or a generic replacement. Early Epson tanks were just that plastic boxes with a sponge inside saturated with ink. There are a few components to the delivery system.

Now I know, unfortunately, that this system is both a blessing and a curse.īefore we delve into how to fix your blank-page-printing problem, a quick explanation on how Epson's ink delivery system works (or, rather, how it appears Epson's ink delivery system works, because Epson isn't exactly willing to divulge its trade secrets) is in order. I was always somewhat suspicious of Epson's philosophy of making the print heads a permanent part of the printer and having the only replaceable part be the ink tanks, but it produced good-looking prints so it didn't bother me. I've owned several Epson printers and have had, generally, good luck with them. After some research, a number of fellow CX5400 owners have reported having the same problems, to the extent that the term "design flaw" became a common theme. Even after doing multiple head cleanings and test prints, pages would emerge from the printer completely blank. Recently, after changing out the blank ink tank on my finacee's Epson CX5400 multifunction inkjet printer, the printer began printing nothing but blank pages.
