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.
Caution- I began buying this model and last made an office order in Dec: Delivered Dec 14- Ran out by Jan 11th-for a small two-person office?? No way. We certainly do not do THAT much printing. I used to buy the knock off toners until they required HP chip to be taken out and put in-didnt work for us...HP STOP BEING GREEDY AND MAKE A MORE AFFORDABLE PRODUCT_ ESPECIALLY WHEN IT HAS TO BE REPLACED MONTHLY!
