It comes down to how much interference you’re seeing from other devices in your area while your machine is sending or receiving information. (That happens during startup, calibration, scanning and after the file preparation stages. Try to not interrupt those processes and it cuts way down on the times you’ll see hangups with the machine. Wait a minute or so after a print finishes before you open the lid too. Give the machine time to take and send the post print shot.)
