I am using this with an old Canon mf624cw printer for business. In the beginning everything was great. Reasonable price, fast delivery. good to go The first one I got had a dotted blue line running down each side as it seemed the reels had been damaged somehow. I asked for a replacement and got it back very quickly. The replacement I received was great, color was great, prints were clean, no complaints. Up to approx. 450 printed pages. The UI shows that there is little magenta and all the reds I print are soft garbage. Also, now every time I print I have to open the printer, take out the cyan, shake it and put it back in. to start a print job. The UI says the cyan cartridge is 75% charged.
