error - print unable 72 on Brother HL-4070cdw
tried brother's solution to open cover for 30 minutes, close, and restart the machine and the code keeps coming back. What is bad? --Brother HL-4070CDW Printer

How do I clear the message "Print Unable 32" from the LCD display?
The message "Print Unable 32" or "Machine Error 32" will appear on the LCD display if paper or labels are stuck inside the printer or drum unit.
[This page gives instructions on how to remove the toner drums and belt, and look around inside for loose paper. I didn't find any loose paper. I found that simply turning the power off and on again will remove the error message and let me print again (so far)]
