Differences Between the D014/D015 & B132/B200
D014/D015/D078/D079 D-2 SM
Overall System
The system timing has been overhauled based on the B132/B200 base control
modules.
IMPROVED RELIABILITY
Longer Service Life of Developer
Servicing has been improved by extending the service life of the developer. This was
achieved by adopting a pre-mixing developer system. Toner and carrier are pre-mixed in the
STC (Soft Toner Cartridge with 90 wt% toner, 10 wt% carrier). The toner and carrier are
supplied together to refresh the developer already in the development units. High image
quality can be maintained for a greater length of time with this system.
Better Stability of Image Density
Compared to the B132/B200, the consistency of the image coverage has been dramatically
increased. This was accomplished by the adoption of the single-direction development
system.
The developer in the D014/D015 development unit is circulated in one direction. This
achieves better uniformity in the application of the toner to the developer sleeve.
Compared to the B132/B200, this means less variation in image density from left to right
and from top to bottom on the output pages.
Ventilation: More Effective Cooling
