Differences from CLC100 Series machines
New sequence of image formation (from YMCK to CMYK)
Increase in the effective image area
No change in intensity/control voltage
No change in basic construction
Addition of a function to change sequence in service mode
No change in control current, method of control, or basic construc-
tion
No change in the height of the charging wire
No change
Increase in the number of rotations of the developing cylinder
Increase in the effective image area
Use of toner of different material
Use of a seamless transfer belt
Different position of the transfer cleaning blade
Eliminating the releasing mechanism of the transfer cleaning blade
Relocation of the oil removing roller and the polishing roller
Use of a transfer cleaning web of a different material
Different blade material, different angle of contact
Different position
Eliminated
No change
Addition of simpler PASCAL (quick correction)
Remarks
Uses common parts
Purpose
To improve the reproduction of images
To support extra-length paper
To correct faulty images in a low humidity environ-
ment
To support the higher process speed
To support extra-length paper
To support the higher process speed
To decrease control mechanisms (e.g., detection of a
seam), to increase life
To prevent displacement of the transfer belt
In relation to the use of a seamless belt
To improve polishing performance
To use a conducing material for removal of charge
from the transfer belt
To accommodate the change of the toner material
To improve charging performance
Owing to the use of a transfer cleaning web capable of
removing charge
