   Epson is notorious for wasting 30% of the ink for cleaning the 
heads.  This printer cleans the heads on its own about every time it's 
used, even only hours apart  The reason it's almost never necessary to 
do a manual cleaning is because it does so many automatic ones.  
Printers are super cheap for the manufacturing costs, carts only have 
13.5 grams of ink and cost a fortune.  It's also why the driver resets 
to Epson Vivid every chance it gets, they make their money off the inks..
