I've not heard of the brand of cartridge you installed. It could very well
be the wrong ink in the cartridge or just as likely you have a restricted
air flow on one of the tanks. Many of the lower cost Chinese cartridges on
eBay have a different air vent on top from Canon and the better third party
vendors. Make sure the tape is fully removed over the vent and that no
adhesive or tape is blocking the opening. The fact that the small squares
are not black is proof that you aren't getting proper ink flow. Note: THIS
IS NOT A CLOG as will be claimed by the moronic troll who constantly
misrepresents what happens when third party inks or cartridges are used. The
most positive (and cost effective) route is to purchase a quality bulk ink
which can be used to refill your empty OEM tanks. Some of the online vendors
also supply unused/empty tanks. Using a bulk ink from one of the vendors
recommended on this newsgroup or
www.nifty-stuff.com will insure that you
get results equal to or better than using OEM ink. My two favorites are
HobbiColors (order on eBay, use Hobbicolors on the search line) and
www.alotofthings.com which supplies Sensient-Formulabs ink. Other quality
vendors are
www.inksupply.com - same as MIS and
www.weink.com. Regardless of
who you order from, check out the alotofthings web site and look at the
various articles Joe has posted concerning refilling. One in particular
deals with the topic of inadequate ink flow due to restricted air flow being
mistaken for clogs.
