Brother MFC-L2701DW printer error "printer unable 03"

[John]

Everyone, please tell me if the Brother 2701 printer often reports error printer unable 03, is it an optical error or a fuser error. Thanks admin for approving

Optical box error, I just encountered a Brother 2701, it was the same. I replaced the laser box and the error was gone.

Replace the entire Laser unit, bro or what?

Buy it and replace the entire unit, the optical motor is stuck or does not rotate enough rpm, it is also an error.

This error is related to the optical box, laser box. Check the optical box cable, and the optical cluster first. Clean the laser box, reconnect the connecting cables. If the error does not go away, replace the laser.
