Frequently drums are damaged in dc12 xerox machine. technician says problem is in electrical input voltage we do all effects to rectify electrical problem but now also the same complaints returns what can i do for save the drum in dc 12 machine

R u replacing only drums

or whole drum cartridge unit

if ur using same unit by changing only drum for more than 2 / 3 drums


u need to change whole at once

bcoz

the charging grid and wire can also damage ur drum

or is their any leakage in developer unit
check for that also
if developer appears on drum unit also damage ur drums
make 2/3 print
check any rough material on ur drum cartridge
solving these 2 issue can solve ur problem
