No paper loaded, I start the printer. It seems to go through an initialization phase, and when I see what to seem to be the left motor turn (with a transparent disc showing numbers) about a third of a turn, then silence, and I see the printer shutting down and restart. While it restarts, even the JetDirect stops answering to pings and the power-on timer on the jetdirect resets.
Using the maintenance utility I can see "printer state: Error 6", which I can't figure what it means.
The LCD then shows this, with the top icons flashing as well as the yellow warning light under the Check button.
I remove the paper roll option, same problem. When the printer is off, I can turn the paper feed assembly and I can't feel it blocking, seems normal to me.
