My question is if anyone has used the MIS K3 equivalent ink set in the 4800, utilizing the funnel fill carts. I have yet to set the 4800 up yet, (having just gotten it a couple of days ago) preferring to read through the manual first, and redesign the area that it will take over!
See the Yahoo Wide Format and Epson 4000 lists for user reports on the funnel fill solution. Most reports I've seen have been positive. The 4800 has a voracious appetite for ink (you'll want to make LARGE prints) I intend to go this route once I've used my first batch of 220 ml carts. See MarkDS' forensic ink cost/use reports for the 4800 in this forum.
Be sure to allow access to the rear of the printer in your install. You need to get to the back to clean the paper path. It's also much easier to insert roll paper from the rear.
Happy printing. It's a great tool.
