Ten refills isn't bad, my Epson R340 died in 3 months and I hadn't
even finished the original set of cartridges. I /finally/ got the
thing replaced this week (if it breaks again I'm going to use a
sledgehammer on it and buy a Canon which I can modify to do CD
printing).
Off-topic but very useful information if you already own one of these
printers: If you have an Epson R-series printer, there's a trap-door
on the back held on by a single screw. You should open this, and find
the clear vinyl tube that routes the waste ink to the base of the
printer. It's got a green stripe on it. The loose end will be pointing
towards the middle of the printer - be careful not to pull the other
end off the print-head assembly - point it out the back of the
printer, and put a cup or something underneath it. There is a program
called the SSC Service Utility that will allow you to reset the waste
ink tank counter, which you should do monthly, which will prevent the
printer from 'shutting down' and requiring an Epson tech to unlock it.
More info can be found here.
http://www.stevesforums.com/forums/view_topic.php?id=51595&forum_id=40The initial head priming of the replacement R340 took 10 ml of ink -
that's nearly an /entire/ cartridge worth of ink. This is necessary,
however, to purge the 'blank' fluid that keeps the printhead from
drying out while it's in storage. To avoid it cleaning the head all
the time, you need to leave the printer on unless you are not going to
use it for an extended period of time. It does a cleaning cycle
with every power on. The R-series are far less likely to clog than the
C-series. You can also modify a C-series printer like this, but it
requires popping the right side of the printer case off or carefully
cutting a hole in the back of it. C-series should be run constantly,
or the Durabrite ink will definitely clog the printhead, even with the
continual cleaning cycles - run a search through comp.periphs.printers
and you'll see over half the complaints are of a Epson C printer
getting jammed up.
I still think the Durabrite ink might be able to print on metal, and
you should be able to trick the R200/300 into using it with swapped
chips, since the printhead is pretty much the same thing, except
6-color instead of 4-color. Not something I'd be trying on my own
since the only reason I bought it is for the CD printing, before I
found out that Canons can do it too.
