I just received and installed our new print head. I don't know yet if it is a dud. Maybe HP shouldn't ask for a review before the consumer has had a chance to use the product.
[This review was collected as part of a promotion.] I purchased this printer from someone and I was so happy. Well I had to purchase UNEXPIRED printheads and ink. It is working perfectly now.
The printheads work great, the plotter that we have is a very reliable and user friendly machine. The website to order parts from is equally user friendly. I ordered the printheads and they were delivered the next day. No problem.
