Differences Between the D014/D015 & B132/B200
SM D-49 D014/D015/D078/D079
DETAILED SUMMARY OF CHANGES
External Appearance, Operation Panel
The operation panel includes a WVGA (Wide Video Graphic Array) Color Touch-Panel
External covers and paper trays are newly designed. Paper trays adopt a new design.
Controller Box
New design. Layout of internal components and PCBs has been changed.
Also, an FCU (Fax Control Unit) is a new option.
Main Frame Configuration, Ventilation
New cooling fans for the development units, and a new cooling fan near the Y PCU on
the left side of the machine.
A heat sink (in the form of a pipe) has been added to the fusing unit to improve efficiency
of cooling.
Engine Drive Mechanisms
PTR motor. A reduction gear has been added to the DD (Direct Drive) motor and
transfer belt cleaning has been improved.
The ITB encoder sensor (FB or Feedback sensors), two separate sensors on the
B132/B200, have been combined into one sensor to reduce cost and improve efficiency.
The used toner horizontal transport path has been extended.
Along with changes in component layout around the drum, new drum cleaning motors
have been added. Each drum cleaning roller is now driven by a separate motor.
The linkage of the OPC drum motors has been improved in order to shorten warm-up
time and to improve the precision of drum rotation.
The design of the output drive shaft used in each development unit has been changed
to reduce wear on the development unit gears.
The drum potential sensors (x4) have been removed from the PCUs and mounted in the
main machine, one above each PCU.
Exposure
Along with improvement in the line speed, the CCD, exposure lamp, scanner motor
have been modified.
In order to reduce costs, newly designed lenses and an ADF exposure glass have been
adopted for this machine.
