There are not Lexmark OEM ribbons but a cheap compatible product in a bulk pack. If you want "compatible" ribbons, you can find them for less than half the price offered here. The listing says these are manufactured by Lexmark, the photo shows a Lexmark package, but don't believe it.
I haven't had problems with these ribbons. I was going to purchase these at a popular office supply store and they were selling these for so much more money. I bought these and paid the same for a box of 6 as I would have for one ribbon at the popular office supply store. Excellent deal!
Another one broke....and printed maybe 25 Bills of Lading. There is something wrong with the production of these cartridges as we have had many that there is a plastic area that often breaks off. This was NOT a HIGH YIELD Re-INKING RIBBON. I turned the arrow and it printed very light as it did when I first put it in the machine. I would like to get a refund on this.
The seller gave me a free third cartridge when I bought two. Sadly, the first cartridge I opened the ink was dried up and wouldn’t show on the paper. Opened the second and it’s the same.
