Non-Use and Refill of BJC-620 Ink Cartridges
(From: Roy (royf@iname.com).)
The people who talk about clogging, etc. must have
never seen a BJC-620, in which the printhead and ink
tanks are separate. I've had a 620 for about 16
months and having printed almost nothing on it (have
a laser for most needs) have noticed that the ink
tanks last about 5 months. My third set of
cartridges at $40 per set have just recently gone
dry. (Actually only the color ones are dry. The
larger black one lasts longer.) I foolishly threw
away the first set of empties, but I still have two
sets. I decided that I've sent enough money to Canon
and searched the web for a more economical solution.
What I found was Bob Nedved and his re.ink.kit
refill kit at:
Re Ink Kit Home Page
where, for $74.50 I got an amount of bulk ink
equivalent to about $800 worth of new cartridges.
Included also are 4 syringes and 4 small screws. The
procedure is to make a small hole in each tank tank
and seal it with a screw. To refill, you remove the
screw, inject a few cc of ink, replace the screw,
and clean the syringe with a little alcohol or
distilled water. Filling the first cartridge was a
little messy, but once you get the hang of it, it's
a snap. The kit doesn't completely eliminate buying
new tanks, because the tanks themselves eventually
need to be replaced, but it sure does cut the annual
maintenance cost, whether you only use the printer a
little or if you use it a lot.

Epson uses a piezo-electric print head, and an
alcohol-based ink. If you don't like paying for
Epson's ink cartridges, use Pelikan's (I think that
is the brand I use - it is certainly one of the
old-fashioned ink manufacturers). They seem to use a
higher molecular weight alcohol than Epson, so the
cartridges last me more like six months than three
in the old (1993) Epson Stylus Q800.
HP and Canon use a water-based ink, that is actually
heated to boiling in the print-head to spit out
droplets - so the print head corrodes rapidly, which
is why their "ink cartridges" contain an new
print-head and only about 15 ml ink, as much as the
print-head can reliably spit out.
