Black Page
Black output is usually caused by an incorrect high voltage in the
printing process, resulting in toner development on the entire
photoconductor drum. Check the condition of each HVPS contact
and make sure they spring back when pressed. Check the continuity
of the HVPS cable. Make sure the following voltages are correct; if
they are not, replace the system board.
Make the following voltage checks while printing and again while
idling. If the voltages are not correct, replace the system board.
