I've had very mixed results with "remanufactured" toner carts. This cart actually seems to have been remanufacturedcertainly not a drill-and-fill. The cart has been re-chipped, and an LJ 4650 recognizes it as HP OEM. Print quality for the month the cart has been installed is excellent.
I bought this cartridge to replace my empty Cyan cartridge on my office printer. The printer is a HP Color Laserjet 4650DTN. The cartridge looked nice and was packaged well. I followed the instructions included on the cartridge and placed it into the printer. Once I closed all the printer doors, the printer attempted to do an "alignment" on the cartridge (as it always does when I put in a new cartridge). The printer started making a loud popping noise, I let it go for about 30 seconds making the noise and then I opened the door to get the printer to stop. I removed the cartridge and looked it over to make sure I didn't miss anything on it, and it looked good, nothing missed. So I again installed it into the printer, and allowed it to do the calibration and again it started with the loud clicking sound. I took the cartridge out for the final time, and replaced it with the old cartridge (which is now working fine, although about out of toner).
I guess I'll be returning this for a refund and try another vendor.
PROS: Looked clean and had the appearance of a better build than other replacement cartridges I've purchased over the years
