There is a Problem with transfer roller: transfer servo start error.
Please try the following:
1. Check HVPS.
2. Check system board.
3. Check HVPS/ input sensor / toner sensor cable.
4. Check the voltage at J15-3.The voltage changes from+24 V dc with the printer idle to 0 V dc when the printer runs the print test. If the voltage is incorrect, check the continuity of line J15-3 in the front cable harness to the HVPS. If there is no continuity, replace the cable harness. If there is continuity, replace the HVPS. If the problem continues, replace the system board.
Alternatively, please contact our Technical Support Hotline.
