As the bumps appear more than once and at a fixed distance, the cause is most likely something stuck to a roller. Measuring the distance between two bumps and dividing by pi will give the diameter of the affected roller.

A service manual for your printer is found here: https://www.manualslib.com/manual/842730/Brother-Mfc-9130cw.html . See page 2-98 for roller diameters.
