Review on 🖨️ CYMBAINK Compatible Toner Reload Kit Replacement for HP 143A 143AD W1143A W1143AD - Compatible with Neverstop Laser 1001nw MFP 1201n 1202nw 5hg80a (Black, Pack of 6) by Thomas Unruh

I bought 6 pieces. They fell out when I loaded them. The reload tube doesn't spin as smoothly as the HP model, it doesn't click like the HP model, and I don't hear the ball inside when I shake it. I've used all 6 in my printer (I print by the ton) and about an hour or two after downloading the latest one, my printer seems broken. I'm getting error A1-5110 which appears to be related to an engine malfunction. DO NOT BUY. Update with more info if it helps someone who is having the same problem: More specifically the error was 59.1000 which is a toner supply motor locking error. Inside the printer is a giant black thing with a pull-out handle called the imaging drum, and in the lower-left corner of the imaging drum (the corner next to the printer's control panel) is a large white gear. This white gear is driven by the black gear on the side of the printer, and the black gear is driven by the toner supply motor. I was able to "fix" the error each time by turning off and unplugging the printer, removing the photoconductor, and manually turning the large white gear counterclockwise half a dozen times. This usually works correctly and will work again for another 100 pages or so. I believe this lousy toner has clogged the inside of the imaging drum making it difficult for the big white gear to turn causing the toner motor to fail and generate an error. Tomorrow I'll get a new drum unit ($70 worth) that might solve this whole problem, but who knows. I'll try to post an update when I find out more. Again, the moral of the story: BEWARE OF THIS PRODUCT.
