Canon iP3300 PIXMA printer. Got new cartridges because of bloom in the others. Just installed them. Now the magenta won't come through. Cleaned and deep cleaned print heads repeatedly. Removed cartridges, reinstalled, removed again and found Magenta ink is dumping into the printer as it should, just not flowing through the machine. Used q-tip to remove large puddle of ink. Need this to work today!! Any suggestions?

thanks!

Lots of questions before I can help. What brand of cartridges are you using? How long has it been since the last time you printed? How old is the cartridge. I know you just installed it, but how long has it been since you bought it
