Yep. I've got the same problem! It has a BLACK cartrdige, of course, in addition to the three colored. But it can't print black without colored because, well, because!
Anyone else noticed how things are just getting more fragile -- rather than better? My Brother printer+fax from thirty years ago still works fine (only sans wireless). But all my five year old newer printers have problems.
And when I look at the newest models they are all, deliberately, severely downgraded in one way or another. In particular, they crave "internet" so they can *automatically* order new "authentic" BrOTHER cartridges when THEY want more money! Or is it just that they want to collect pictures when I go to Hooters?
