6042 Drum DRUM: Hall velocity error - more than 20 percent during drum init. All This error is reported if the drum velocity as read by the encoder differs by more than 20% from the targeted drum init velocity, i.e. gross velocity error. This may be caused by setting drum hppr incorrectly. Also loose drive belt, loose pulley, damaged motor ( try "drum spin 60 c" ), grossly out of calibration drum amp (do "drum cal" and save it), faulty drum amp control/data cable. Resume and report to Creo Response center. Also note velocity error message on diagnostic monitor if possible. drum hppr set incorrectly Loose pulley Damaged motor Grossly out of calibration drum amp. Faulty drum amp control/data cable.
