Canon PFI-300 Lucia PRO Ink, Cyan, Compatible to imagePROGRAF PRO-300 Printer

These inks are okay and they print okay but the downside is that they only offer 14 grams of ink per cartridge. They show the weight between 18-22 grams when empty. I weighed the cartridges when they were empty and when they were full. Empty, they vary between 18 and 23 grams. The Canon Pro-300 printer registers the cartridges are empty between 18 to 23 grams! That means there is a variable of 5 grams of ink in the cartridge that the printer is not detecting! Very inconsistent and very costly over time. When I open a fresh ink cartridge and weigh it (without the cap), the cartridge weighs anywhere from 30 to 32 grams. Doing the math, it appears you get between 10 grams of ink on the low end and a maximum of 14 grams on the generous end. The ink also clogs easily. And if you have to flush the lines to keep the lines from clogging, it runs into a lot of money just keeping the lines clean. There is an inherent problem with the canon PRO-300 printer as I found out from the manufacturer (Canon) after speaking with tech support. The printer does not register the ink levels properly and this also runs into wasted money down the drain.

As described.

Excellent product!
