To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I initially thought this was incompatible with my Pantum wireless printer because the printer would always return a message that no cartridge was installed. It turns out that the metal circuit contacts on the cartridge were dirty. I wiped those clean, and plugged the cartridge in, et voila!
I bought the Pantum P2502W when it first came out, it was really a good price. The original toner cartridge finally died a few weeks ago so I bought this. Lifted the old cartridge out, dropped in the new one, & its off to the races. Turned it on, found a printer test page online, tried it, & it worked fine. Just like it is supposed to.
The product is what I ordered but I thought they might have sent some installation instructions. This was the first replacement and I did not make original installation so I was flying blind, but it worked fine. Hope it is good for the 1600 copes they advertised.
