Comparing the V-C1 and V-C2/V-C3
! In the V-C2/V-C3 series, the path for fresh developer is separate
from the path for excess toner scraped from the development
roller by the doctor blade.
! In the V-C1 series, the excess toner mixes with fresh toner.
! The V-C2/V-C3 series achieves a more even coating of toner on
the drum and uses only fresh toner/developer. This means the
density of the image is more uniform.

# This is a schematic view.
# The one-direction flow of developer in the V-C2/V-C3 series development unit
improves image quality.
# Fresh developer: pink
# Excess toner: pale blue
# V-C2/V-C3: Carrier goes to the development sleeve and on to the drum
# V-C1 series: Carrier goes to the development sleeve and comes back again.
Then it is mixed with fresh developer, but the older carrier has less chargeability,
and this can cause image density to vary across the page.
