Your machine ventilation fan is not working, usually due to a foreign material being stuck at the fan or the fan is faulty or the PCB is faulty.

Brother mfc465-cn unable to init 49


Error 49 relates to the print head drive voltage. It may just need the flat ribbon cables that connect the head to the main pcb reseating, but equally it may need the print head replacing (most likely).
An outside chance that the main pcb will need replacing.

In theory, all of these jobs are a task for an engineer. Brother UK (0870 830 400) can pass you on to a repair agent.
