The Epson 3640 is one thirsty machine. I am not a heavy user but my ink bill soon swamped my purchase price. It uses an amazing amount of colored ink considering most of my printing was black only. After around 8 months the print quality became unacceptable. The helpline walked me through numerous head cleaning/nozzle checks over a two day period. The result was a slight improvement in print quality but the lines are around 5 degrees above horizontal! It prints at a slant! Unbelievable!The desk admits it is a hardware problem, and I have since found other similar reviews online. I should have done my homework. I hope this helps you in that regard.
