I have a 7800. I believe the 7880 (90) are built the same way.
There was a class action lawsuit (USA) several years ago about the fact
that
there is ink left in the carts when the printer stops. Epson lost the
lawsuit,
but several things came out of it.
First Epson uses Piezo heads and has repeatedly stated that
running the head out of ink can damage the head. The ink also
acts as a coolant.
Secondly, the larger (than the 2200) printers have very long feed lines.
If the carts run dry, the lines can get bubbles in them and/or feed
erratically. This might necessitate purging the lines which wastes
more ink than the small amount left in the carts.
The lawyers who sued Epson made a couple million and each of
us in the class got a coupon good for 10% discount at the Epson store.
So guess who won?
