I¹m curious what you are experiencing with ³refilled² toner cartridges. Here is my experience: 1. They seem to be running out faster which might indicate less ink to begin with. However, it is only my impression, not an exact measurement and is subject to human recollection! 2. My black cartridge is running out when the gauge still shows 25%. I use the printer regularly but it says I should get 425 more pages. 3. The color ones show 50% left after only 47 pages when they are supposed to do 900 pages. The color pages were full-color coverage on 25% of the page. The problem may be the reused cartridge(s) show an incorrect level. Just wondering if you¹ve had similar experiences.
