..

This is a possible printhead problem. Call brother may times they will do it was a warranty repair even after the warranty period.

hi good day! the printer is error 50 due to a paper or some sensor error.. open the printer, or dismantle, clean the sensor and wash the pump of water and change the waste pad of new absorber. locate the sensor under the pump, clean it of alcohol.

A 50 error code indicates a problem with the "maintenance unit".
This unit controls and cleans the printhead and ink delivery system. You will need a technician to figure out if this is the problem or some other component has failed.
