First time using remanufactured cartridges for this printer. I've had trouble cleaning the printheads almost every time I've used the printer with the recommended new stock cartridges. It only used up ink and often had to buy replacements, which became costly. I just wanted to destroy the printer. Decided to try these reloaded cartridges first. They seem to have solved the constipation problem. So next time I will stay with them.
