I bought a new HP color laser printer (HP M451DN). It came with “starter” toner cartridges, good for 1,400 pages (supposedly). I had a big print job, with 1/2 page color, so I knew I wasn’t going to get that many pages out of them (the page rating is for 5% coverage, which is a bit absurd). After 350 pages, the Cyan low warning came on. I actually thought that wasn’t too bad, since thats 1/4 of the rating, and I was using almost 10x the coverage.
The printer lets you ignore the warning, by pressing the OK button, although it nags constantly. So I kept printing. And pressing the OK button. And printing. And pressing the button. And printing some more.
One by one, all the other colors ran low, and they all had the same damn warning. Now I was pressing OK every few pages. But I still kept printing. I looked at each page, and they all looked fine. When I had printed another 215 pages, I noticed the first hint of toner fading.
So, HP wants me to replace the (expensive) toner when it’s a little more than 1/2 empty!
I mean, it’s one thing to have the low toner warning come on when the toner is really low. It’s another to expect the user to just throw away $100 worth of product for no good reason.
