The 59.F0 has been a common error code on the HP CLJ M452 and M377/M477 MFP models. The printer’s service manual references this error in relation to a “drum motor assembly,” but in most cases has been resolved by replacing the Transfer Belt assembly (RM2-6454). The belts have an internal failure that prevents the secondary transfer rollers from engaging, and need to be replaced as a whole unit.
