OK, how about telling us which printer ;-) (as in which model)?
You reset the cartridge AFTER you refill, if you are going to refill.
However, if you just intend to empty the remaining ink in the cartridge
then you can reset it before refilling and reinstall it and use up the
ink, but the printer will not stop to warn you it has run out of ink
when it does.
There are two ways to reset cartridges, one is internal to the printer,
using the Russian Utility, (I assume they provide instructions when you
download it), or you buy a chip resetter for that cartridge type often
from ebay, or another source for a few bucks. They use a battery to
provide the energy to do the reset.
