I'm using a Brother HL-1470N printer on my current network. It has worked fine for several years, but now has a problem. When I send a print job, the printer wakes up, but all the status lights come on and occasionally blink. They stay on for several minutes, then usually go off and the printer works fine (until it goes to sleep again). Any ideas as to why it's acting this way? The Brother manual is worthless in diagnosing this problem.
