HP 37Y Black Extra High-yield Toner Cartridge | Works with HP LaserJet Enterprise M608, M609 Series, HP LaserJet Enterprise MFP M631, M632, M633 Series | CF237Y

37Y says it is a high capacity toner but it will not fit a machine that uses 37A. Bought 2 from Amazon. Opened the box and it would not fit the machine. Sealed the box back and dropped at UPS office with a QR code. Quick and easy return. Refund hit my account a few days later after the return was processed at Amazon.

A toner cartridge that can give you upwards of 40,000 pages before needing replacement? Crazy, you may say. In this case, however, it's true. I've been through multiple of these toner cartridges, as I do a lot of high-volume printing each month for a business. This is truly the best bang for your buck if you insist like me on using OEM cartridges.

Producto de primera, con alto rendimiento

It said it fits my HP M607, indeed, it is not. I could not put the cartridge into the toner tray!!!!! I either need to return the item & refund me; or if someone can guide me how to make it fit into the tray. We paid hundreds for this high yield toner!

Super bueno

Item was delivered as expected

Long lasting and as promised.

We just purchased this toner and the cartridge is leaking all over our paper and smudging, and we are having to reprint a lot of documents. I finally had to replace it, after only using for a few weeks. I can find no way to contact the seller.

TENIENDO EN CUENTA EL AHORRO EN EL PRECIO, ESTA OPCION DE TONER RESULTA EXTRAORDINARIAMENTE VENTAJOSA. QUEDA VER SI LA LARGA DURACION NO AFECTA A LA CALIDAD DE IMPRESION, AUNQUE LO CREEMOS IMPROBABLE.
