I have been having trouble with Canon PG-40 black cartridges...all have acted like the heads were plugged shortly after refilling them. Prior to being refilled, they all worked great, but were getting low on ink. These were OEM carts, so they hadn't exceeded their life expendency . With a little research, I have discovered on 2 different Canon websites, that 1 sells OEM carts with pigment black ink & the other site with Chromalife 100 dye based ink. My bulk ink is pigment black ink. If I am refilling dye based carts with pigment ink, could that cause my head plugging ?
Thanks..
