@mukuba Print Unable 71 error message has to deal with the laser unit polygon motor. On most Brother machines the laser unit does not start up until it starts to print. If the motor does not get to operating speed in a set amount of time then the machine will produce a "Print Unable 71" error message. It is possible that this is caused by failed lubrication in the polygon motor bushing. You can try to S

1. Turn the machine off then back on

2. Replace the Laser Unit or Clean and Lubricate the shaft and bushing with a light weight lubricating oil

3. Replace the Main Board PCB
