Blocked heads used to be a serious problem on Epson printers five years ago and more, particularly with pigment inks, but I don't think it's much of a problem any more.
Vincent on Photo-i fired up his 2100 for a review, probably to compare with the 2880, and he had not used it for a year. He might have done a single head clean but basically it just worked straight off - and this is two or three generations before the 3880.
I have not used my R1800 for a couple of months at a time without having any problems. I don't recall even needing to clean the heads at any time except when I had a banding problem caused by an incorrect profile, though I might be wrong about that.
I did have a serious problem with "blocked heads" when I had an R800 until I worked out that that was due to letting air into the lines by running the inks too low. The R1800 seems much more forgiving on this.
Image Science has new 3800s for $1945 and the cheapest price on
http://www.shopbot.com.au is $1855, so $1400 is probably a reasonable price.
I'm also contemplating a 3880, especially if my
forthcoming exhibition proves reasonably viable. OK, the coated head's a good thing. From my limited understanding, I'm more interested in the increase in gamut and the smoother transitions from an improved method of laying down the inks. Monochrome especially could be a significant improvement over my R1800.
The 3800 can print beyond the prescribed 37" (if I remember the length correctly) using the Quad Tone RIP for black and white only - and therefore presumably the 3880 will be able to also. there's also a
German freeware utility that worked with earlier versions of the 3800 and might be updated for the 3880. However, according to the documentation on that site, the earlier version of the driver is still available for download and you can switch between the two without problems (ie for the 3800). You might possibly need different custom profiles, though.
I agree there's no point buying one if you're not going to make use of it. It will come with say $800 of inks for $2000, compared to an R2880 for about $1200 with about $200 of inks so it's fairly attractive in those terms. The cost of the 3800/ 3880 cartridges is relatively high but the cartridges are much larger than A3 cartridges and even with discounting for A3 printer cartridges the cost of ink (R1800 vs 3800) remains about the same. I understand, though that the 3800/ 3880 will be a little bit more efficient in their use of the ink.
It I go ahead with trading up to the 3880, it wil probably be in January or February because prices are often a bit lower after the initial period.
