>>Epson says once a cartridge is installed and the seals are broken the ink is good for 6 months
I didn't know that!
>>Always make sure and run a nozzle check before you start any print job when the printer has been idle for over a day.
Gee, didn't know that either!! Other than aligning the print head at the set up, I haven't done any maintenance work after buying it. I remember reading somewhere about the print head purging ink every time it is switched on, because of that I switch it off only once a fortnight.
BTW, I didn't really "upgrade" to a 3880, just bought one. Getting rid of crappy old four colour canon/hp printers prior to buying a 3880 can hardly be categorized as upgrade!!
