Review on Z Ink Replacement Brother TN450 by Chadwick Webster

The first cartridge I installed had no toner on the left side of the page. The right side was also very weak. I shook the cartridge as instructed, installed it as instructed and nothing. So I went online to find out if anything else was wrong. I went through all the fade toner troubleshooting methods but nothing helped. The last suggestion is to replace the toner. So I took out the second cartridge and installed it exactly like that, making sure to follow the directions exactly. This works fine. So 50% failure is very bad. However, the one that works works well. But I spent about 30 minutes getting the first one to work. Now it's in the trash along with the old toner I wanted to replace.
