To calculate the overall star rating and percentage breakdown by star, we don’t 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.
Bought and sold by amazon not third party. The HP cart was Original as you would expect from Amazon, Toner cart 131x gave me 2865 prints in black average print coverage of 6%. The warning of low toner came on when page count hit 2500. printed a further 365 until i notice the first sign of toner fade. with another shake of cart i will probably get another 120.
Page count information can be found by typing printer ip address into your internet browser, ip address can be obtained looking on the screen of printer and touching the network logo
example on internet explorer in the address bar type 192.168.0.22 then press enter key on keyboard, than select supply status.
Please share your print counts, does any one have the count for a 131a cart? like to know the difference between normal and high capacity
I always buy the 'real thing' and I am very happy with it, including the cost. I have used others with my previous printer, but I do not want to take the risk of buying a substitute as I cannot deal with the stress of it spoiling my printer, and in the long run, I don't think that you save that much (if any) money. Just ensure you click 'continue using' when it tells you that it has nearly run out, as you can still get a lot of perfect copies. I tell it it is OK a number of times, until it does actually run out.
