I'm with "stanbrown" on this one; my Epson 4000 is a piece o' junk. What an expensive disappointment!
I purchased my printer after extensive research online. All the reviews raved about this printer, much like this review. I paid $2500 at the time and got nothing but a briefcase full of blues in return. The lines are constantly clogged and the ink is extremely expensive. One must Power Clean to unclog the lines. This uses vast amounts of ink and rarely works. (Question: If one color line is blocked, why must I use up all the other colors when cleaning it?)
Several online competitors came out with ink cartridges for the 4000 and the competition made the prices very reasonable, but then Epson sued. Now one must buy solely Epson replacement ink cartridges and pay a premium for them.
I've used my Epson 4000 a couple dozen times, then emotionally walked away from it because of endless frustration and expense.
To those who love this stinking, unworthy beast, I have one that you can buy from me - CHEAP. It's like new. I bought the custom cabinet, too. You'll have to pay for shipping.
