I bought 4 of these about a year ago, all have failed to print well after several months. Checking page count are are under 2000 pages when they start to print poorly. Original HP toners last 3 to 5 times longer and print much better from the start.
Two have started to print poorly after only two weeks.
Ok... back to paying too much for OE HP toner, it ultimately cost less in the long run.
