The error indicates a high voltage problem with the primary or transfer units. The most likely cause is the main drum being worn out.
This can be checked by going into service mode. You can do this by pressing the star button once, then press 2 and 8 at the same time, then the star button again. Now a word of warning. Do not change anything as it is very easy to turn your copier into a cabage!!! Press the tab marked COPIER, then the one called DISPLAY, next the one called MISC. You will see an item called DRUM LIFE, if it is 80 or more the drum will need replacing. Hope this helps.
