The toner is the successor product to the original toner with me. The shipping was lightning fast and the toner came very safe packed. The instructions are only in English, but with existing school English or a translator should not be a problem. The installation still is not difficult: the toner is moved a little to distribute evenly around the content. One then needs to remove a very obvious white placard. Now, the cap has to be removed. The manual is now reading from a piece of paper that is to be removed. I have found none. Despite the best effort I could not find one. As was already mentioned, but in a previous review, I have it waived continue to search in vain. The toner was lodged, started the printer, it rattles a bit, and he was ready to print. The levels can not be played with me, but that could be due to my operating system or the alternative of the printer menu. I have already printed some leaves and the quality seems to be the original. Deep color, no smearing. I hope it stays that way. If the quality remains and keeps as indicated, then I'm very confident of this product.
