Hi Luciano, so it can be seen in the photo, the fuser is not new, maybe it is repaired, but now the jam is in the second transfer zone but it can be produced by sensors for the taking of paper, paper passage and exit of fuser by measuring the closing and opening time of the same, the sensors can be measured by entering a diagnostic menu, before cleaning thoroughly with a degreaser and then rinsing the rollers with the M1 label with water (the paper passes between the two rollers , and the pick up of the trays, also the error can be in that the paper is not correctly taken by the rollers and brakes at some time, check the final fuser output sensor, the flag sensor will see it on the side of the fuser output I await your comment or question and experience, best regards
