I thought that the ink cartridges that came with my new printer would last longer than they did. When I needed to replace them, the ordering process was easy. However, I did have difficulty finding the directions for replacing the cartridges. The instructions never said that all 4 cartridges must be replaced at the same time. I also needed to find a visual for removing the orange plastic thing. Granted, I am not very tech-savy, but I can follow directions if they are provided. I should not have to go looking for them.
