BCI-6 tanks don't need to stand for any appreciable period of time after
refilling. You do need to permit any ink that will drip out of the outlet
port to do so before replacing the cart into the printer. If you have a
good seal on the refill hole the dripping will stop after just a few drops
and will not leak into the printhead.
Burt, there are two kinds of 3rd party BCI-6 cartridges, one with yellowish
sponge and the other with white one. The one with yellowish sponge has higher
capillary force to hold ink while the white one has less. There are different
consequences as a result of different sponge used.
The one with higher capillary force will exhibit better holding of ink and is
less likely to cause leaky printhead. But this kind of cartridge is more likely
to develop a blockage in the sponge eventually and cause printhead clog. On the
other hand cartridges with white sponge is more likely to leak ink out of the
printhead, especially if overfilled. But they have the advantage of less likely
to cause printhead clog.
Canon OEM cartridges use white sponge, if you take a look yourself. Canon does
not fill ink into the sponge fully, leaving some white sponge exposed at the top.
This tells how Canon OEM cartridges are NOT overfilled.
This is what I have observed from the 3rd party virgin cartridges I have used.
Both of them have worked well for me. But the one with white sponge can be easily
overfilled and cause ink to leak out from the printhead. The vendor specifically
warned about it and provided instruction how to NOT overfill them. They do work
wonderfully if ink is correctly filled.
Just thought to comment on the general techniques in refilling. Thanks a lot to your
contribution to this NG.
BTW, MK does deserve a point against refilling with 3rd party ink. Canon OEM carts
are used only once. So the chance of developing a blockage in the sponge is nearly
none. But with refilling the probability is increased regardless what sponge in what
cartridge is used. So let's stop attacking him and hope in return he will stop his
attacking attitude either but posting fair opinions of his only. I am sure this NG
will be more peaceful for everyone to post different opinions. For now I do not read
his posts because too much nonsense is in them most of the time.
