[QUOTE=Dana-IJM;4009]Hmmm… Epson can’t answer questions about their own printers?? I would take a guess and say there’s about 5-7ml of ink in each line from cartridge to print head, but I don’t know for sure, nor do I know the total ink used during a power clean cycle.
Power clean cycles are needed when dealing with settled pigment after the printer has sat unused for a period of time (but is best to avoid settled pigment by regularly agitating ink carts and using the printer at least once a week).
It’s possible that excessive cleaning cycles of any kind can be harmful to a printer, but we have done the recommended 3 power cleans when changing inks or flushing our 3800/3880 printers over the years and have not experienced any issues, nor has anyone reported problems after doing this with their 3800/3880 printers.
Yup, Epson Tech support, hit and miss at best. (Canon is the same for their printers)
On a 3880, in addition to agitating the carts, what print size would you print weekly to keep the ink fresh?
