as lines that are spaced 51.02 mm apart indicate you should check the transfer roll for damage and
check for toner or foreign material buildup.

Check the voltage at J22-3. 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 J22-3 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.
