Vertical Void or Streak
Do a developed image test to determine if the defect is occurring before
or after the transfer process.
If you see the defect on the photoconductor, check the operation of the
printhead shutter and clean the printhead window with a lint-free cloth
folded over a cotton swab; do not use a bare swab and do not use any
cleaning fluids or water on the printhead window. Inspect the HVPS
contacts.
If the image on the photoconductor is good, inspect the fuser rolls and
transfer roll. Make sure the left transfer roll bearing is contacting the
contact from the HVPS. Make sure the HVPS contacts are clean and
spring back when pressed.
