The quality of Canon toner cartridge I bought were bad. First the magenta leaked within the seal bag, and the replacement magenta toner still leaked in a controlled way that displays random lines and dots on the print out. Black toner can only prints light gray after 2 weeks of installation. Yellow and cyan fares better with random occasionaly color issue, especially if left with no printing for a few days. Customer service and response is OK, but was never offer to replace the entire package, only piece meals. I was so annoyed that I bought another set from different vendor, and they all worked fine. This is the only time they can make money from me.
