I use the large capacity compatible cartridges in a Canon N2000 and have
never had ONE problem. Not even a clog. Mine uses the 12XX series and
I get them for about $20/cartridge from this site: http://www.neximaging.com/ Paying $130/cartridge is pretty steep even
with the large capacity. If the W8400 has chipped cartridges then your
only option would likely be to refill the old carts if the printer
firmware allows it.
Yes, but the prints are significantly larger, and the percentage of
coverage is very high depending on the print type, so the per print
capacity of the cartridge isn't what you might think. At $1,000 for a
set of OEM cartridges is ridiculous pricing by any standard, IMO. My
N2000 would be $240 per set and with compatibles I pay less than $80 per
set shipped to my door. The OP can probably save about $600-$700 per
set using compatibles. That is a lot of money in my world!
